Phase I - Limited Site Investigation
Hudson, Massachusetts
Dear Mr. Walton:
In accordance with our proposal dated November 12, 1990, GZA
GeoEnvirormental, Inc. (GZA) has conducted a Phase I - Limited Site Investigation
of the Chase-Walton facility in Hudson, Massachusetts. This report has been prepared
in accordance with the Limitations and Terms and Conditions in Appendix A.
This report describes the conditions observed by GZA at the study site. The text
presents the observations made during site reconnaissance; information gathered
during site history research and regulatory agency file review; and data generated in
the subsurface exploration, sampling and chemical screening programs.
On the basis of data gathered during our study, it is our opinion that volatile organic
compounds (chlorinated solvents) are present in the groundwater at the site. The
source of these contaminants could not be identified based on the limited data
available. It is also our opinion that the site should be classified as a "non-priority"
disposal site under the guidelines of the Massachusetts Contingency Plan.
A Subsidiary of GZA
GenEnviinmental
Technologies, Inc,
We have appreciated the opportunity to work with you on this project. Should you
have any questions, please call the Associate Principal identified below.
Very truly yours,
GZA GEOENVIRONMENTAL, I NC.

1.00 INTRODUCTION
(Ffm
In accordance with our proposal dated November 12, 1990, GZA GeoEnvironmental,
Inc. (GZA) has conducted a Phase I - Limited Site Investigation as defined in the
Massachusetts Contingency Plan (MCP; 310 CMR 40.000) of the Chase-Walton
Elastoners, Inc. facility at 29 Apsley Street in Hudson, Massachusetts. The Site Locus
is on Figure 1. The site's Universal Transverse Mercator (UTM) coordinates are
4,969,200 meters north and 286,177 meters east; its latitude and longitude are
420 29'00" north and 71- 34'47" west, respectively.
The purpose of GZA's Phase I - Limited Site Investigation was to: (1) render an
opinion as to whether the site is a "disposal site" as defined under the MCP; (2)
provide data and analyses with which the Massachusetts Department of Environmental
Protection (DEP) may determine whether the site will be classified as a priority or
non-priority disposal site and whether further investigative or remedial action is
necessary at the site; and (3) identify the source of volatile organic compounds
reported in groundwater at the site. The study included:
-
a site reconnaissance to observe site conditions;
-
review of a previous study (August 1990) of the site performed by Wehran
Engineering Corporation;
-
contact with local officials and review of state and federal files and lists to
provide further information on environmental concerns at or near the site;
-
subsurface explorations in the form of shallow test borings and the installation
of four monitoring wells;
-
collection and analysis of soil and water samples;
-
a wellhead elevation survey to evaluate groundwater flow direction;
-
review of potential contaminant migration pathways and receptors; and
-
the preparation of this report.
This report is subject to the limitations contained in Appendix A.

2.00 BACKGROUND
Chase-Walton Elastomers, Inc., is located at 29 Apsley Street in Hudson,
Massachusetts, and is involved with the manufacture and worldwide distribution of
hoses and gaskets for automobiles and aircraft, and inert silicon tubing and implants
servicing the medical profession. Site background data is provided in the following
sections.
2.10 SITE DESCRIPTION
The 1.25-acre Chase-Walton Elastomers, Inc. (Chase-Walton) site consists of a
C-shaped two-story manufacturing and office building, a three-story storage building,
paved parking, and landscaped areas. The south central portion of the manufacturing
facility is occupied by SF Medical Corporation (SF), a subsidiary of Chase-Walton.
The industrial-zoned site is located in an industrial and residential neighborhood. Site
abutters include Middlesex Research and Manufacturing Company to the west, Apsley
Street and an unpaved parking lot across Apsley Street to the north, a large building
containing Four Star Connections, Inc., and the Town Crier Press to the east, and
unused railroad lines to the south. Hudson Lock, Inc., is east of the abutting property
on the east side of the site.
The site is serviced by municipal water, sewer, and stormwater drainage lines from
Apsley Street, and electricity. It is heated by natural gas and oil. Site features and
utilities are shown on the Exploration Location Plan, Figure 2.
2.20 TOPOGRAPHY AND DRAINAGE
The study site and surrounding area are relatively flat and are located at the base of
a small hill to the west of the site. The site slopes slightly to the northeast. Surface
runoff from the paved central portion of the site flows into four catch basins which in
turn drain to a concrete pipe that discharges to an open, concrete-lined ditch along the
east side of the storage building. Flow from this drainage ditch enters the municipal
stormwater drainage system beneath Apsley Street. According to the Town of Hudson
Department of Public Works personnel, the municipal drainage stormwater system
from Apsley Street flows to Bruce's Pond, approximately 1/2 mile east of the site.
According the U.S.G.S. Topographic Quadrangle Map (Hudson Quadrangle, 1978),
Bruce's Pond empties into an unnamed stream which discharges to the Assabet River,
approximately 1/2 mile southeast of the site. Based on topography, the direction of
regional groundwater flow is expected to be southeast toward the Assabet River, which
flows east. Further discussion of groundwater flow direction at the site is provided in
Section 6.20.

2.30 SITE HISTORY
Ugm
To obtain information concerning the history of the site, we reviewed Sanborn Atlas
maps at the Hudson Library and information at the Hudson Assessors' and Licensing
Offices. According to the Sanborn Atlas maps, the current Chase-Walton site was a
portion of a larger industrial facility which dated back to at least as early as the late
1800s. An atlas dated 1894 showed several structures on the site; occupants at that
time were listed as the Millay Last Company (southwest corner) and the Apsley
Rubber Company. Railroad tracks are shown adjacent to the south side of the
property. In 1903, the maps indicate the area immediately east of the site was
occupied by a smoke stack and two long rectangular structures: one used for grinding,
cutting, packing, shipping, and gum storage by Apsley Rubber Company, and the other
involved with wood and coal storage by Atknight & Company. Railroad spurs are
shown leading to each structure. In 1929, the site and adjacent properties were used
by the Firestone-Apsley Rubber Company and contained several structures, which
included: a vulcanizing building and a mixing building with spreaders; railroad tracks
are shown adjacent to the south side of the property. According the Hudson Licensing
Office, a building, presumably the storage building, was constructed on the
Chase-Walton site with a concrete foundation and brick and concrete walls in 1920.
According to the Assessors' Office, the current owner is Mr. James C. Walton/
Chase-Walton Elastomers, Inc.; the property is identified on Map 18, Parcel 200,
Book 12595, page 347. Chase-Walton Elastomers purchased the property in 1955 from
Textile Rubber and Combining Company, which had owned the site since 1951.
Structures were added to the site in 1970 and 1984.
2.40 PREVIOUS STUDIES
As part of the present study, we reviewed reports documenting previous investigations
at the site and an adjacent parcel. Our reviews of these reports are outlined below.
2.41 Chase-Walton Site
An August 1990 report entitled "Environmental Site Assessment for the ChaseWalton Property, Hudson, Massachusetts" was prepared for Chase-Walton by Wehran
Engineering Corporation (Wehran) of Methuen, Massachusetts. The assessment
included: a site visit, research into site history, review of regulatory agency files and
a limited subsurface exploration program, consisting of completion of two borings (B-I
and B-2), installation of one monitoring well (MW-1 in boring B-2), soil and
groundwater sampling and chemical analyses. Pertinent data from Wehran's study is
included in Appendix B.
The principal findings of Wehran's studies involved the detection of volatile
organic compounds (VOCs) and petroleum hydrocarbons (PHCs) in soil and
3
groundwater at the site. Specifically, Wehran reported elevated VOC levels in three
soil samples from well MW-1 based on photoionization detector readings (13 to 30
parts per million, or ppm). Their results also indicated PHC levels of 30 and 130 ppm,
respectively, in soil samples from boring B-1 and well MW-1. The VOCs
trichloroethylene (TCE) and 1,2-dichloroethylene (1,2 DCE) were found in a
groundwater sample from MW-1 at 1.3 and 0.03 ppm, respectively.
The report stated one 5,000-gallonfuel oil underground storage tank (UST) and
one 2,000-gallon fuel oil UST were located near the manufacturing facility and storage
building, respectively. These tanks were tightness tested "recently" and passed. The
2,000-gallon fuel tank was reported to be out of service by Wehran. They concluded
that the soil contamination at the site could possibly be related to the USTs. Wehran
also concluded that the groundwater at the site "contains trichloroethylene exceeding
drinking water and groundwater standards, however, the source and extent of the
contamination is unknown."
The report also recommended notification to the Massachusetts DEP Central
Regional Office in Worcester, Massachusetts, and completion of a Phase I - Limited
Site Investigation to determine the source of the TCE.
2.42 Hudson Lock Site
GZA also reviewed a report obtained from DEP files, entitled "Phase I Limited Site Investigation Report (Site No. 2-0736) Hudson Lock, Inc." and prepared
for Hudson Lock, Inc. by Jason M. Cortell and Associates, Inc., of Waltham,
Massachusetts in May 1990. The Hudson Lock Site is about 300 feet east of the
Chase-Walton property.
The report indicated five 20,000-gallon USTs containing No. 4 and No. 6
heating oil were installed in a concrete vault at the site in the 1940s. These USTs
were removed in July through September 1990, and contaminated soils were observed
at the tank locations. The stockpiled contaminated soils were analyzed and removed
from the site by Brox Development, Inc., in May 1990. The report stated that the soil
contamination "resulted from overflow of a dike that was constructed to contain oil
spilled when valves were opened and closed during tank filling." Groundwater was not
observed in the vault after exposure for several days. The report suggested no further
remedial action was necessary.
3.00 OIL AND HAZARDOUS MATERIALS USAGE
On December 27, 1990, GZA personnel, accompanied by Mr. Sean Walton of
Chase-Walton Elastomers, Inc., visited the exterior of the site and the interior of the
4
elastomer manufacturing facility and the storage building. The purpose of this visit
was to observe existing conditions, review oil/hazardous materials usage and evaluate
surficial evidence of the presence of oil or hazardous materials. The interior of the
SF Medical facility was not observed to preserve the sanitary conditions of the
operations. The site features are shown on Figure 2.
(f9a
The exterior of the site is mostly paved with bituminous concrete or concrete, except
for a small grassed area at the southeast corner and along the northern and western
boundaries. The interior of the C-shaped main building is two stories high. The first
floor is concrete-lined with no floor drains, and includes most of the site operations
areas. These included: a research and development/quality control laboratory,
braiding operations, molding ovens, a small machine shop, and a cafeteria. According
to Mr. Walton, a large concrete-lined vault below the floor contains waste hydraulic
oil which is removed by Clean Harbors approximately every two years. The chemical
storage area is attached to the eastern side of the main building. No indications of
spills or stains on the floor were observed. The machine shop contained lathes, drill
presses, metal work benches and metal shelves which contained several 1/2 to 1 pint
containers and spray cans of hydraulic oil, paint, hydraulic oil solvents, and machinery
lubricants (WD-40). The second floor contained offices with two rest rooms, copy
equipment, and a small utility closet with a few small containers of cleaning agents.
The chemical storage shed is bermed along the edges with no floor drains and
contained a total of ten 55-gallon drums of toluene, isopropanol, naphtha, waste oil,
and adhesive. The contents of each container was marked with a label on the outside.
Mr. Walton indicated that a few 1-gallon containers of naphtha are used throughout
the main building to clean the machinery. A list of the chemicals used at the facility,
provided by Chase-Walton's Vice President, Mr. Thomas Maroney, is presented on
Table 1. According to this information, Chase-Walton does not use or store
chlorinated solvents at the site. Chemical wastes generated in Chase-Walton's
processes are transported offsite for disposal by Clean Harbors, Inc.
The three-story brick storage building is unheated and is used to store cardboard for
packaging the finished products, rejects, and machining parts. The basement is
frequently flooded and contains sump pumps in the elevator shaft below the level of
the concrete floor which discharge into an outdoor concrete-lined trench adjacent to
the east wall of the building. According to Mr. Walton, the sump pumps run
frequently. Water stains were observed along the walls and the wooden support beams
at heights of 2 to 3 feet above the floor level. The elevator pit was also full of water.
Mr. Walton indicated the main building is heated with oil contained in one
5,000-gallon heating oil UST located near the center of the site, and one 2,000-gallon
heating oil UST located adjacent to the southeast corner of the storage building.
GZA personnel did not observe oil staining in the vicinity of the tank fill pipes. Use
5
of the 2,000-gallon tank has been discontinued; Mr. Walton indicated that
Chase-Walton is presently making arrangements to remove the tank.
4.00 REGULATORY INFORMATION CONCERNING SITE AND VICINITY
Certain state and local agencies were contacted and certain state and federal files and
lists reviewed to assess whether hazardous material or oil may have been released into
the soil or groundwater at or near the site. Some of the information was developed
by telephone contact; other information is the result of direct interviews and visits.
The information made available to GZA during these visits, interviews and file reviews
is summarized in the following paragraphs.
4,10 LOCAL
To obtain information concerning the possible release of hazardous material or oil at
or near the study site, GZA contacted the Hudson Licensing, Health, and Fire
Departments. These agencies did not have knowledge of problems involving oil or
hazardous material release incidents at the site and were not aware of any public or
private water supply wells in the area. The Fire Department did not have records of
the USTs on the Chase-Walton site. However, there were records of a 10,000-gallon
No. 5 fuel oil UST on the westerly abutting Middlesex Research site.
4.20 STATE AND FEDERAL
Files made available to GZA at the DEP Central Regional Office were reviewed on
December 17, 1990. Additionally, we reviewed several lists from state and federal
agencies which we maintain in-house. These included:
-
the Massachusetts Department of Environmental Protection (DEP) Site
Assessment Database dated July 19, 1990;
-
the DEP Spills Database updated through May 14, 1990;
-
the DEP January 31, 1991 "List of Confirmed Disposal Sites and Locations To
Be Investigated";
.
DEP's Water Supply Protection Atlas;
-
the Environmental Protection Agency (EPA) list of hazardous waste generators
under the Resource Conservation and Recovery Act (RCRA) files dated
February 9, 1990;
6
the DEP's RCRA files;
-
the EPA Emergency Response Notification System (ERNS) list dated May 29,
1990, of spills reported to EPA;
-
the EPA's 1981, 1988, 1989, and 1990 lists of permitted surface water
discharges under the National Pollutant Discharge Elimination Systems
(NPDES);
*
-Y
+
EPA's Facilities Index System (FINDS) list dated August 27, 1990, of sites
monitored under any of 12 EPA regulatory programs;
EPA's Comprehensive Environmental Response Compensation and Lability
Information System (CERCLIS) list, dated September 12, 1990, of sites for
possible investigation under the Federal Superfund Program; and
-
EPA's National Priorities List (NPL) dated September 12, 1990.
These documents indicated the presence of numerous properties within a 1/2 mile
radius of the site where oil or hazardous material release incidents have occurred or
which are involved in various EPA monitoring programs. None of the reported
incidents or sites would be anticipated to affect the subject site, with the exception of
a release incident at the Chase-Walton facility (see below), and a reference to the
westerly-abutting Middlesex Research and Manufacturing Company. The latter was
identified on the EPA FINDS list as a regulated facility under EPA's Air and
Radiation Monitoring Program.
Chase-Walton received a written Confirmation Of Responsibility (COR) letter dated
March 27, 1985, from DEQE (now known as DEP), Central Region, regarding an
investigation conducted on March 2 and 3, 1985, (attached in Appendix C). This
investigation was related to a release of waste hydraulic oil/hazardous material ("waste
solvents and unidentified pail of white liquid"), which occurred in the facilities storage
area. The letter outlined four deficiencies with the storage, handling, and labelling of
various containers of oil and hazardous materials. In particular, DEP determined that
materials had discharged directly to a downgradient catch basin from the storage area,
and drums were observed outside the storage area without covers enabling rain water
to "collect and discharge oil/hazardous materials onto the pavement and into area
catch basin." The catch basin was connected to the stormwater drainage system which
ultimately discharges to Bruce's Pond.
DEP's correspondence did not characterize the specific nature of the materials
released, but references were made to "waste hydraulic oil" and "waste solvents."
Mr. Sean Walton indicated that the company addressed the problems identified by
DEP shortly after the incident.
7
A subsequent letter from the Solid and Hazardous Waste Division of the DEP dated
June 14, 1985, requested Chase-Walton to file for an EPA Identification Number as
a small quantity generator of hazardous waste under RCRA. A copy of this letter and
an associated memo are also included in Appendix C. Currently Chase-Walton is
listed as a small quantity generator (Facility Identification No. MA D001407055).
5.00 FIELD EXPLORATION, SAMPLING, AND ANALYTICAL PROGRAM
GZA completed a field exploration and analytical program to assess the areal extent
of VOCs and PHCs detected in site soil and groundwater by Wehran. Our sampling
and analytical program included installation of monitoring wells, collection of soil and
water samples from the borings and wells, collection of samples of surface water
discharges from the site, and a wellhead elevation survey.
5.10 SUBSURFACE EXPLORATIONS AND MONITORING WELL
INSTALLATIONS
On January 2, 1991, four borings were completed by GZA Drilling, Inc., of Brockton,
Massachusetts. Hollow stem auger techniques were employed without the use of
drilling water. Well GZ-3 was installed near the presumed upgradient edge of the site
and well GZ-2 was installed near stormwater and sewage drainage lines. Wells GZ-1
and GZ-4 were installed in the paved parking area south of Apsley Street and beside
the railroad tracks on the south side of the site to provide better site coverage.
Exploration locations are shown on Figure 2.
An observation well consisting of 10 feet of 2-inch-diameter PVC wellscreen attached
to solid PVC riser pipe was installed in each boring. All PVC attachments were
completed without the use of solvents or glues to prevent contamination. The
wellscreen was set to span the water table encountered during drilling. A filter of
clean silica sand was placed in the annular space around the wellscreen, and a
bentonite clay seal was placed above this filter sand. Each well was completed with
a road box. Well installation details are presented on the boring logs in Appendix D.
5.20 ELEVATION SURVEY
An elevation survey was conducted by GZA personnel on January 2, 1991, using
standard survey techniques. A benchmark established by a previous survey was used
and is referenced to National Geodetic Vertical Datum (NGVD) of 1929. The
elevation of each well casing was established, referenced to this benchmark.
Groundwater levels measured with an electric water level indicator on January 2, 1991
were used along with well casing elevations to establish groundwater elevations. These
are summarized on Table 2.
8
530 SOIL AND WATER SAMPLING
Split spoon soil samples were obtained by Standard Penetration Tests at 5-foot
intervals during the drilling operations. Soil samples were classified by the on-site
geologist; boring logs developed by GZA are attached as Appendix D. A portion of
each soil sample was collected in a clean glass jar, stored in an ice-packed cooler, and
transported under chain-of-custody procedures to GZA's Environmental Chemistry
Laboiatory (ECL) for chemical screening and analysis.
QK%
On January 2, 1991, GZA personnel sampled the observation wells at the study site.
Water samples were obtained using 5-foot stainless steel bailers with Teflon balIcheck
valves. A separate laboratory-cleaned bailer was used for each well to avoid crosscontamination. Three times the initial standing volume of the groundwater in the well
was evacuated to remove stagnant water, and the well was allowed to recharge. Water
samples were collected in 40-ml vials with Teflon septa, and in 1-liter amber glass jars.
The samples were kept cooled and delivered to GZA's ECL under chain-of-custody
procedures.
GZA personnel measured water levels in each GZA monitoring well and in MW-1
prior to sampling. The depths to water table and groundwater evaluations are
presented in Table 3.
In addition, GZA personnel collected a sample of steam condensate from a pipe on
the north side of the main building (labelled C-1) and discharge water flowing in the
concrete trough along the east side of the storage building (labelled D-1).
5.40 CHEMICAL SCREENING AND ANALYSES OF SOIL AND WATER
SAMPLES
Soil samples collected from the site were screened in GZA's laboratory for total VOCs
using an H-Nu Model PI-101 photoionization detector (PID) with a 10.2 electron volt
lamp. The PID measures relative levels of VOCs referenced to a benzene-in-air
standard. Although the PID screening cannot be directly used to quantify VOC
concentrations or identify individual compounds, the results can serve as a relative
indicator of the levels of VOCsin each sample. A description of GZA's PID screening
procedures is included in Appendix E; results are discussed in Section 6.30.
Groundwater samples, steam condensate, and one drain sample were screened for
VOCs by static headspace gas chromatograph (GC) techniques. The GC screening
analysis permits the tentative identification and approximate quantification of
individual VOCs. Descriptions of the GC screening procedures for water samples are
included in Appendix E; results are summarized on Table 3 and discussed in
Section 6.30. In addition, water samples were screened for pH and specific
conductance. The pH is a measure of the acid or basic nature of water, and specific
9
conductance is a measure of dissolved ions in water. An Orion Research Model 701A
Digital Ionanalyzer was used to measure pH, and an Extech Model 440 Digital
Conductivity Meter was used to measure specific conductivity.
Two groundwater samples were also analyzed for PHCs by a petroleum hydrocarbon
fingerprinting technique (modified ASTM Method D3328). Results are presently in
Appendix E, along with a discussion of the analytical methodology.
6.00 STUDY RESULTS
The following section summarizes the soil and groundwater conditions at the site and
outlines results of chemical screening.
6.10 SUBSURFACE CONDITIONS
Soil conditions are summarized from Wehran's boring logs (Appendix B) and GZA's
boring logs attached as Appendix D. Wehran's and GZA's borings were advanced to
depths between 14.5 and 16.5 feet below grade. Wehran borings encountered 5 to
8 feet of granular fill overlying sand. Boring B-2 (MW-1) encountered clay and silt
below the sand at a depth of 10 feet. Subsurface materials encountered by GZA
consisted of approximately 2.5 to 6 feet of granular fill, underlain by 2.5 to 6 feet of
silty sand which graded to a sandy silt. Glacial till, a dense heterogeneous mixture of
sand, silt and gravel, was encountered below the silty sand at an approximate depth
of 8.5 feet in boring GZ-4.
6.20 GROUNDWATER FLOW
Groundwater was encountered at approximately 7 to 8 feet below grade throughout
the site. Based on the wellhead elevation survey and groundwater levels measured on
January 2, 1991, groundwater flow at the site appears to be generally toward the east.
Groundwater levels appeared to be slightly depressed in the vicinity of sanitary sewer
and storm drainage lines indicating potential effects from these utilities. The various
subsurface drainage structures at the site, dewatering associated with the basement
sump pumping at the storage building, and heterogeneous soil conditions complicate
an evaluation of groundwater flow conditions at the site. Available data are
insufficient to reliably characterize flow due to the apparent complexity of site
hydrogeology.
10
6.30 RESULTS OF CHEMICAL SCREENING AND ANALYSES
Q7M
y
PID readings on soil samples ranged from below detection limits to 2.4 ppm; these
levels are not indicative of significant concentrations of VOCs in soils. VOC screening
of water samples did not detect synthetic VOCs in three of the five monitoring wells
at the site and in the two surface water samples. VOCs were found in well MW-1 and
in newly installed well GZ-2. TCE and 1,2-DCE were reported in the sample from
MW-1 at levels of 0.130 ppm and less than 0.050 ppm respectively; results from a
sample from well GZ-2 indicated TCE present at less than 0.050 ppm. It is noted that
TCE levels detected in well MW-1 are one-tenth of the concentrations reported by
Wehran in 1990. These levels are still substantially higher than the current drinking
water standard for public water supplies for TCE (0.050 ppm).
The PHC-fingerprint analyses did not detect dissolved petroleum products in samples
from wells MW-1 and GZ-2. The pH ranged between 6.3 and 8.0 for groundwater and
7.4 to 6.5 for the condensate and process water respectively. Conductivity values
ranged between 364 mhos/cm and 878 ymhos/cm for groundwater, and 101 to
203 pmhos/cm for the condensate and drain water, respectively. The pH and SC
values observed in groundwater samples are consistent with values commonly observed
in groundwater throughout New England.
7.00 POTENTIAL MIGRATION PATHWAYS AND RECEPTORS
7.10 POTENTIAL MIGRATION PATHWAYS
VOCs have been found in groundwater samples from two monitoring wells (MW-1 and
GZ-2) near the central portion of the site. It is anticipated that these contaminants
will migrate generally eastward toward Bruce's Pond, although they may discharge to
nearby storm and sanitary sewer lines. Given the low hydraulic conductivities of soils
at the site (based on sample descriptions from the boring logs), contaminant migration
via groundwater flow will be limited.
7.20 POTENTIAL HUMAN HEALTH CONCERNS
Humans are isolated from direct contact with the chemicals detected in the site soil
and groundwater due to the presence of pavement and uncontaminated surficial soils.
No active drinking water supply wells have been identified in the vicinity of the site.
Based on the available data, air emissions from the compounds in the soil and
groundwater are anticipated to be negligible or non-detectable under present
conditions. In summary, potential human health concerns associated with the observed
contamination are limited. Human exposure would only occur if contaminated soils
were excavated.
11
7.30 POTENTIAL ENVIRONMENTAL RECEPTORS
Environmentally sensitive areas as defined by the Massachusetts Contingency Plan
include wetlands, areas subject to 100-year flooding, and sensitive terrestrial/aquatic
habitats. GZA has reviewed a number of state and federal sources for information
regarding the presence of such environmentally sensitive areas within the vicinity of
the Chase-Walton site in Hudson, Massachusetts.
The groundwater in the contaminated portion of the site appears to be moving in a
generally easterly direction. The likely receptor from on-site groundwater and surface
water drainage is Bruce's Pond, which is located approximately 1/2 mile east of the
site. Bruce's Pond serves as a tributary to the Assabet River; the confluence of these
two waterways is approximately 0.7 of a mile southeast of the site. Ultimately the
Assabet drains to the Concord River approximately 7 miles to the northeast.
Bruce's Pond, part of the Assabet River Basin, is classified as pallustrine open water
on the U.S. Fish and Wildlife Service National Wetland Inventory Map for the Hudson
quadrangle. The water quality of the Assabet River is classified by the DEP Division
of Water Pollution Control (DWPC) as Class B (314 CMR 4.00, the Commonwealth
of Massachusetts DWPC Surface Water Quality Standards, 1988). Class B waters are
designated for the uses of protection and propagation of fish, other aquatic life and
wildlife; and for primary and secondary contact recreation. Surface runoff throughout
much of the basin has contributed to elevated nutrient levels that resulted in increased
phytoplankton counts and subsequent diurnal dissolved oxygen fluctuations (The
Commonwealth of Massachusetts Summary of Water Quality DWPC Appendix IV Non-Point Source Assessment Report, 1989).
According to the Massachusetts Division of Fisheries and Wildlife, fish species
believed characteristic of the Assabet River include: Pumpkinseed (Lepomis gibbosus),
Banded Sunfish (Enneacanthus obesus), Redfin Pickerel (Esox americanus
americanus), Creek Chubsucker (Semotilus atromaculatus), Brown Bullhead (Ictaluras
nebulosus), Golden Shiner (Notemigonous crysoleueas), Chain Pickerel (Esox niger),
American Eel (Anguilla rostrata), White Sucker (Catostomas commersoni), Bluegill
(Lepomis machroshirus), Brook Trout (Salvelinus fontinalis), Yellow Perch (Perca
flscens), Banded Sunfish (Lepomnis aritus), Largemouth Bass (Micropteris
salmoides), Black Crappie (Poxomis nigromaculatus), Fallfish (Semotilus corporalis),
and Yellow Bullhead (Ictaluras natalis).
The site is not within the 100-year floodplain of the Assabet River as defined by the
Federal Insurance Rate Map No. 255209 004C Panel 4 dated July 4, 1988. The site
is not in the vicinity of any Areas of Critical Environmental Concern (ACEC) as
defined by the Massachusetts Coastal Zone Management Office, or in any U.S. EPA
Priority Wetlands.
12
No rare wetland wildlife habitat is known to be located within two miles of the site
(Massachusetts Natural Heritage and Endangered Species Program, Atlas of Estimated
Habitats of State-listed Rare Wetlands Wildlife, 1990 Edition).
VOCs recently detected on site include DCE and TCE at concentrations ranging up
to 0.130 ppm in groundwater. The concentrations of VOCs in the groundwater were
not above any of the U.S. EPA Ambient Water Quality Criteria for the protection of
freshwater aquatic life. Accordingly, it is unlikely that VOCs in soil and groundwater
will pose a threat to ecological receptors in the vicinity of the site.
8.00 SUMMARY AND CONCLUSIONS
A Phase I - Limited Site Investigation was completed at the Chase-Walton Elastomers,
Inc., facility in Hudson, Massachusetts. The study included a site reconnaissance, a
review of site history, a review of available local, state and federal regulatory records,
a review of a previous study, and a limited subsurface exploration and testing program.
On this basis of the work conducted as part of this site evaluation, GZA has reached
the conclusions described below.
-
Chase-Walton Elastomers, Inc., has occupied the site since 1955, manufacturing
hoses, gaskets and specialized tubing. Prior to their purchase of the property,
the site and surrounding parcels had been used by various rubber
manufacturers and other industries. Industrial usage of the site dates back to
at least as early as the late 1800s.
.
Chase-Walton stores and uses a variety of organic solvents at the site. There
are also two UST for fuel oil on the property of 2,000-gallon and 5,000-gallon
capacity. The 2,000-gallon UST is out of service and is scheduled for removal.
-
A previous incident (March 1985) involving spillage of waste oils or solvents at
the site was documented in DEP files. Spilled material entered a catch basin
and flowed to Bruce's Pond via the municipal storm drainage system under
Apsley Road. Chase-Walton addressed the incident and upgraded their
chemical storage facilities.
-
A previous environmental study at the site identified petroleum hydrocarbons
and VOC in soil and groundwater at the site. VOCs found at elevated levels
in groundwater included trichloroethylene (TCE) and 1,2-dichloroethylene
(1,2-DCE).
13
.
Recent sampling of groundwater at the site confirmed the presence of TCE and
1,2-DCE but levels were lower than those previously reported. VOCs were
found only in two wells within the central portion of the site, adjacent to storm
drain lines.
-
Groundwater flow in the area of the site appears to be generally to the east;
however, characterization of groundwater conditions on-site is complicated by
the presence of underground drainage lines and pumping from a basement
sump.
-
A review of potential human and environmental receptors for contamination
migrating from the site indicated only limited potential for exposure.
Based on our observations and testing, it is our opinion that the Chase-Walton site
would be considered "a disposal site" in accordance with the definition in the MCP.
The site does not appear to meet any of the criteria for a priority disposal site under
the MCP; accordingly, it is our opinion that the site should be classified as a nonpriority site.
The source of the VOCs reported in groundwater at the site could not be conclusively
identified. We did not see evidence of usage by Chase-Walton of the specific
constituents detected (TCE and 1,2-DCE).
Based on this information, these
constituents may be related to past activities at the site or could potentially have
originated from an off-site source. Further study would be required to characterize
the source and potential effects of the observed groundwater contamination.
9.00 LIMITATIONS
GZA's Phase I - Limited Site Investigation was performed in accordance with
generally accepted practices of other consultants undertaking similar studies at the
same time and in the same geographical area, and GZA observed that degree of care
and skill generally exercised by other consultants under similar circumstances and
conditions. GZA's findings and conclusions must be considered not as scientific
certainties, but rather as our professional opinion concerning the significance of the
limited data gathered during the course of the Phase I - Limited Site Investigation.
No other warranty, express or implied, is made. Specifically, GZA does not and
cannot represent that the site contains no hazardous material, oil, or other latent
condition beyond that observed by GZA during its Phase I - Limited Site investigation.
This report his also subject to the specific limitations contained in Appendix A.

SITE ASSESSMENT LIMITATIONS
1.
The observations described in this report were made under the conditions stated therein. The
conclusions presented in the report were based solely upon the services described therein, and
not on scientific tasks or procedures beyond the scope of described services or the time and
budgetary constraints imposed by Client. The work described in this report was carried out in
accordance with the attached Statement of Terms and Conditions.
2.
In preparing this report, GZA GeoEnvironmental, Inc. has relied on certain information provided
by state and local officials and other parties referenced therein, and on information contained in
the files of state and/or local agencies available to GZA GeoEnvironmental at the time of the
site assessment. Although there may have been some degree of overlap in the information
provided by these various sources, GZA GeoEnvironmental did not attempt to independently
verify the accuracy or completeness of all information reviewed or received during the course of
this site assessment.
3.
In the event that bank counsel or title examiner for Client obtains information on environmental
or hazardous waste issues at the site not contained in this report, such information shall be
brought to GZA GeoEnvironmental's attention forthwith. GZA GeoEnvironmental will evaluate
such information and, on the basis of this evaluation, may modify the conclusions stated in this
report.
4.
Observations were made of the site and of structures on the site as indicated within the report.
Where access to portions of the site or to structures on the site was unavailable or limited, GZA
GeoEnvironmental renders no opinion as to the presence of hazardous material or oil, or to the
presence of indirect evidence relating to hazardous material or oil, in that portion of the site or
structure. In addition, GZA GeoEnvironmental renders no opinion as to the presence of
hazardous material or oil, or to the presence of indirect evidence relating to hazardous material
or oil, where direct observation of the interior walls, floor, or ceiling of a structure on a site was
obstructed by objects or coverings on or over these surfaces.
5.
Unless otherwise specified in the report, GZA GeoEnvironmental did not perform testing or
analyses to determine the presence or concentration of asbestos or polychlorinated biphenyls
(PCB's) at the site or in the environment at the site.
6.
The purpose of this report was to assess the physical characteristics of the subject site with
respect to the presence in the environment of hazardous material or oil, as defined in
Massachusetts General Laws Chapter 21E. No specific attempt was made to check on the
compliance of present or past owners or operators of the site with federal, state, or local laws
and regulations, environmental or otherwise.
7.
The conclusions and recommendations contained in this report are based in part upon the data
obtained from a limited number of soil and/or groundwater samples obtained from widely spaced
subsurface explorations. The nature and extent of variations between these explorations may not
become evident until further exploration. If variations or other latent conditions then appear
evident, it will be necessary to reevaluate the conclusions and recommendations of this report.
8.
Water level readings have been made in the test pits, borings, and/or observation wells at the
times and under the conditions stated on the test pit or boring logs. However, it must be noted
that fluctuations in the level of groundwater may occur due to variations in rainfall and other
factors different from those prevailing at the time measurements were made.

9.
Except as noted within the text of the report, no quantitative laboratory testing was performed
as part of the site assessment. Where such analyses have been conducted by an outside
laboratory, GZA GeoEnvironmental has relied upon the data provided, and has not conducted
an independent evaluation of the reliability of these data.
10.
The conclusions and recommendations contained in this report are based in part upon various
types of chemical data and are contingent upon their validity. These data have been reviewed
and interpretations made in the report. As indicated within the report, some of these data are
preliminary "screening" level data, and should be confirmed with quantitative analyses if more
specific information is necessary. Moreover, it should be noted that variations in the types and
concentrations of contaminants and variations in their flow paths may occur due to seasonal water
table fluctuations, past disposal practices, the passage of time, and other factors. Should
additional chemical data become available in the future, these data should be reviewed by GZA
GeoEnvironmental, and the conclusions and recommendations presented herein modified
accordingly.
11.
Chemical analyses have been performed for specific parameters during the course of this site
assessment, as described in the text. However, it should be noted that additional chemical
constituents not searched for during the current study may be present in soil and/or groundwater
at the site.

WRITTEN CONFIRMATION OF
RESPONSIBILITY
Dear Mr. Moroney:
As a result of an investigation conducted by Department of Environmental Quality
Engineering (DEQE) on March 2 and 3, 1985, the Department has determined that there
has been a release of unknown quantities of waste hydraulic oil/hazardous material
(waste solvents and unidentified pail of white liquid) from the oil/hazardous material waste drums and containers stored at Chase-Walton Incorporated, 29 Apsley Street,
Hudson, Massachusetts. In addition, the Department has determined that there existed
a threat of release of oil/hazardous material from the drums and containers in question during the storage periods of February 26, 1983 through March 2, 1985.
The information obtained during the investigation revealed that:
1.
Sixteen (16) assorted containers with various capacities (11-55
gallon drums, 2-25 gallon plastic drums, 1-5 gallon steel drum
and 1-24 gallon plastic pail) which contained oil/hazardous
materials, were stored during February 26, 1985 through March
2, 1985, in an outside parking area at the rear of Chase-Walton
Incorporated;
2.
With the exception of one (1) empty 55 gallon steel drum the
remaining storage containers present at the site were full to
capacity or partially filled with oil/hazardous materials;
3.
The majority of drums were mislabeled, not properly labeled,
and/or not labeled at all. Positive identification of all
drum contents could not be determined by labeling or facility
personnel; According to your testimony you stated that a number
of drums contained waste hydraulic oil generated from repairs
made to one o.f the facility's hydraulic presses.
4.
Some drums were not equipped with covers which enabled rain
water to collect and discharge oil/hazardous materials onto
the pavement and into area catch basin. Some drum opening
caps were not securely tightened;
5.
The storage area location was upgradient and adjacent to a
storm water catch basin which the Department has determined
ultimately drains into waters of Bruce Pond;
6.
Speedy dry had been applied around the drums and that the
speedy dry present was heavily stained and contained absorbed
oil;
7.
Observations of the storage area revealed that the pavement
immediately around the drums was oil stained and that the oil
stain path lead to the down gradient catch basin.
8.
Observation of the catch basin cover, down gradient from
the drums indicated that oil/hazardous materials had been
discharged directly to and entered the catch basin; and
9.
The facility did not undertake measures to provide for the
security of oil/hazardous materials being stored.
Such incident is governed by Chapter 21E of the General Laws of Massachusetts
(hereinafter "M.G.L.c.21E"), the Massachusetts Oil and Hazardous Material Release
Prevention and Response Act which was enacted on March 24, 1983, through Section
5 of Chapter 7 of the Acts and Resolves of Massachusetts of 1983.
The Department has determined that you are, under the provisions of M.G.L.c.21E,
Section 5(a), responsible for the occurrence of such release/threat of release.
On March 3, 1985, at approximately 8:22 a.m. Department personnel verbally notified you of your responsibility for such release/threat of release and gave you one
copy of a document prepared by the Department and entitled "Brief synopsis of M.C.L.
c.21E, the Massachusetts Oil and Hazardous Material Release Prevention and Response
Act". You accepted such responsibility at that time.
Your acceptance of responsibility for such release/threat of release means that
you have (1) entered into a contract with a cleanup contractor, approved by the Department, named Zecco, Incorporated, to take all necessary remedial and/or preventive
response actions (i.e., assessment, containment and/or removal actions) relative to
such rlease/threat of release ; and (2) pay (paid) for (a) all response costs incurred
by the Department due to such release/threat of release and (b) all damages sustained
from any injury to or destruction or loss of natural resources due to such release/
threat of release.

d47.-
The Department of Environmental Quality Engineering on April 19, 1985
conducted an inspection of this facility located at 29 Apsley Street, Hudson,
Massachusetts. The purpose of the inspection was to perform a routine evaluation
of the facility's hazardous waste activities.
The inspection revealed the following:
1.
The facility manufactures silicone rubber hoses, medical rubber
products, tubing, and sheets, using silicone rubber as the
raw material.
2.
The processes involved in manufacturing these products are:
calendering, hand lay-up, steam curing, mixing, extruding, braiding,
jacketing, and molding.
3.
The facility is a waste oil generator.
4.
Waste solvents generated from cleaning operations are: naphtha,
mehtyl.alcohol, and methyl ethyl ketone (MEK).
The facility has no EPA ID number, therefore, not classified as
a Generator at the present time.
5.
6.
The facility has set-up a storage area for hazardous wastes
(waste oils and solvents). These deficiencies were found in
the storage area: (1) the 55-gallon drums for hazardous wastes
were not properly marked and labelled, and (2) the storage
area was not posted with a "Danger - Unauthorized Personnel
Keep Out" sign. (Mr. Moroney was advised to correct these
deficiencies.)
Discussions with Mr. Thomas Moroney, company representative, revealed
that the facility generates approximately 100 to 150 gallons per year of waste
solvents. This estimate was also stated in Mr. Moroney's April 15, 1985 letter
to the Central Region's Office of Incident Response. In addition, the letter
stated that approximately one hundred (100) pounds of oil soaked Speedi-Dri
andprobably fifty (50) gallons of oil (lubricating and hydraulic) are generated
per year.
Based on this inspection and review of the Department's records, it appears
that this facility is qualified for Small Quantity Generator (SQG) status. Per
estimate, the facility would generate between 20 and 1000 kg. of non-acutely
hazardous waste in a month.

Attention:
Mr. Thomas S. Moroney
Vice President
Dear Mr. Moroney:
The Department of Environmental Quality Engineering, on April 19, 1985,
conducted an inspection of your facility located at 29 Apsley Street, Hudson,
Massachusetts. The purpose of the inspection was to perform a routine inspection of your hazardous waste activities.
The inspection revealed that your facility generates small amounts of
waste solvents in addition to waste oil.
Please be advised, if you do not generate more than 20 kg. per month
of non-acutely hazardous wastes, you are not required to have an EPA Identification number. However, if you exceed this limit, your facility becomes
a Small Quantity Generator (SQG). A Small Quantity Generator (please see
attached definition of SQG), is required to notify the EPA and the Department of Environmental Quality Engineering of its hazardous waste activities.
During the inspection you have expressed your plan of getting an EPA
Identification number. This is advisable at the present time.
In the future, if you do not exceed the 20 kg. per month limit, you may
notify the EPA and the Department of Environmental Quality Engineering to
withdraw your EPA Identification number, and your facility's status will
then be changed from SQG to INACTIVE.
Chase Walton, Incorporated
June 14, 1985
Page 2
Enclosed please find a form which you must complete and submit to the
EPA in case you want to obtain an EPA Identification number at this time.
If there are any questions, please call Cecilia M. Catalan of this office
at (617) 792-7653.
Very truly yours,

GZA SCREENING TECHNIQUE FOR THE DETERMINATION
OF SEMI-VOLATILE COMPOUNDS IN AQUEOUS SAMPLES
OVERVIEW
The methodology employed by GZA to determine semi-volatile compound concentrations in aqueous
samples was developed in accordance with guidelines specified for the Massachusetts
Department of Environmental Quality Engineering (DEQE) for determining phthalate esters and
adipates in aqueous samples. The method was subsequently expanded to encompass EPA Method
610 compounds, polyaromatic hydrocarbons (PAH's). As a whole the method is reliable for the
determination of the above named semi-volatile compounds.
METHODOLOGY
A forty milliliter aliquot is removed from the sample and extracted in a two phase process.
Phase one is the addition of 1ml of methanol to the forty ml sample. After agitating this
mixture for one minute, using a Vortex Genie, the second solution of 4mls of hexane is added
and the sample is re-agitated. The mixture is allowed to settle into phase layers for
approximately one half hour before an aliquot of the hexane layer is removed for analysis.
INSTRUMENTATION
The prepared extract is analyzed for semi-volatile organic content using a HP 5890A Gas
Chromatograph equipped with twin flame ionization detectors and a dual column capillary inlet
system. The two Megabore capillary columns chosen for the analysis are a 30meter HP-1 and a
30meter DB-624. The fifty-five minute analysis is electronically controlled by a HP 7673A
Autosampler and data is acquired with a Nelson Analytical 760 Series Intelligent Interface.
The chromatographic data is then transmitted to an IBM AT personal computer and analyzed
using the Nelson Analytical 2600 Series Chromatographic Software. The information for the
analytical report is entered manually onto a Lotus Symphony Spreadsheet. The automation of
the system allows the analyst to set optimum sample arrangement including calibration
standards, method blanks, and duplicates.
CALIBRATION
To demonstrate the extraction efficiency of the method the gas chromatograph was initially
calibrated using external standards of semi-volatile spiking solutions. For daily
calibration known standards are prepared in hexane at concentration levels that bracket the
expected sample concentration. Sample peaks are identified by comparing retention times to
the measured retention times of the calibration standards. Data must agree on both columns
before positive identification of a semi-volatile compound may be made. Quantities are
determined utilizing response factors yielded by the calibration.
REPORT FORMAT
The method detection limit for each compound has been determined empirically and is modified
for each sample as a function of the dilution factor. The total concentration for all
detected compounds is summarized in the row marked 'Total Compounds'. All reported results
for semi-volatiles screening of aqueous samples are reported in ug/ml (ppm) unless otherwise
indicated. Trace levels are those levels calculated between one and five times the stated
detection limit.
DISCLAIMER
Identities and concentrations of semi-volatile compounds reported in this screening method
are subject to the limitations inherent in this method. This method is not definitive and is
not an EPA approved analytical. If confirmation is desired samples should be submitted to a
State Certified Laboratory for analysis by the appropriate EPA protocol methods.

GZA HYDROCARBON FINGERPRINTING TECHNIQUE
BY GAS CHROMATOGRAPHY-FLAME IONIZATION DETECTION
(PHC FINGERPRINT, GC-FID)
OVERVIEW
The methodology employed by GZA to determine hydrocarbon content in solid and aqueous
environmental samples is a modification of ASTM Method D3328-78 in conjunction with a
method developed by the U.S. Coast Guard. Data obtained by this method include an accurate
total concentration of hydrocarbon content and an identification based on comparisons with
laboratory petroleum standards. Identifications may also be made utilizing a virgin
petroleum product acquired from a suspected source at the site.
METHODOLOGY
Solid samples are extracted using a 30 gram subsample which is initially mixed with
anhydrous sodium sulfate (Na2SO4) to remove water from the matrix. The sample is
subsequently mixed with pentane to form a slurry which is then extracted via sonic
disruption. This process is repeated three times and the collected extract is cleaned up
using a silica gel solid phase extraction (SPE) column. The collected elutriate is
automatically concentrated to a 1 milliliter volume with a Zymark Turbovap Evaporator to
enhance detection limits of the method. Aqueous samples are extracted using a 200ml
aliquot In a liquid/liquid extraction device using the solvent pentane. The extraction is
repeated three times and the resulting extract is prepared following the same method as
with solid environmental samples.
INSTRUMENTATION
The prepared extract is analyzed for hydrocarbon content using a Hewlett Packard Model
5890A Gas Chromatograph equipped with twin flame ionization detectors and a dual column
capillary inlet system. The two Megabore capillary columns chosen for the analysis are a
30meter DB-5 and a 30meter DB-1. The sixty-five minute analysis is electronically
controlled by a HP 7673A Autosampler and data are acquired with a Nelson Analytical 760
Series Intelligent Interface. The chromatographic data are then transmitted to an IBM AT
personal computer and analyzed using the Nelson Analytical 2600 Series Chromatographic
Software. The information for the analytical report is entered manually onto a Lotus
Symphony Spreadsheet. The automation of the system allows the analyst to set optimum
sample arrangement including calibration standards, method blanks, and duplicates.
QUALITY CONTROL
The gas chromatograph is calibrated using an average response factor determined for
hydrocarbons that is calculated from internal and surrogate standards. The calibration is
checked with every batch of samples by analyzing petroleum hydrocarbons of known
concentration. Identification of petroleum product type is made by comparison with
laboratory standards or with suspect petroleum sources on an individual site basis.
Tracer compounds such as the isomer pair phytane/ n-octadecane are routinely used to
determine the degree of product 'weathering' as in the case of fuel oil number 2. The
surrogate standard o-terphenyl is added to samples and method blanks to determine the
extraction efficiency of the applied method as a surrogate recovery.
REPORT FORMAT
The method detection limit for total hydrocarbon content has been determined empirically
and Is modified for each sample as a function of the dilution factor. The total
concentration is summarized in the row labeled 'Hydrocarbon Content'. All reported
results for hydrocarbon analysis environmental samples are reported in ug/g (ppm) unless
otherwise indicated. Detection limits for individual hydrocarbons are reported for the
purpose of determining levels of priority pollutant constituents of petroleums such as
polyaromatic hydrocarbons (PAH's). Surrogate recoveries are reported for all method
blanks and samples.
DISCLAIMER
Identities and concentrations of petroleum hydrocarbons reported in this analytical method
are subject to the limitations inherent in the cited methods. This method is not an
approved EPA method but Is currently undergoing a review by the ASTM Committee D-29 on
water for upgrades and certification.
