2015 Annual Water Quality Report Inside
From the Desk of the Superintendent
I am pleased to present to our customers this issue of Water Talk which
includes Massapequa Water District’s Annual Water Quality Statement. This report is mandated by the
US Environmental Protection Agency and NYS Department of Health.
The report contains the various constituents and analytical results that
we are required to test for. The Massapequa Water District continues to supply the highest quality drinking water at a reasonable cost. During the past year, MWD has completed several capital projects which have replaced or upgraded the
infrastructure of the District. These projects include the following:
• The refurbishment of the Brooklyn Ave ground storage tank. This
project included painting the exterior of the tank and adding a
specialized coating to the interior. Th is tank stores 500,000 gallons of
water used during periods of high demand.
• The implementation of a water meter replacement program. This
program identifies the replacement of several hundred meters
within the District on a continuous basis each year.
• A fire hydrant replacement program, where over 70 hydrants were
replaced in 2015. This program is expected to continue for the
next several years until all outdated hydrants are replaced.
The Board of Commissioners continues to balance funding for these
projects by utilizing reserve funds with limited bonding.
On behalf of the Board of Commissioners, I would like to wish all residents an enjoyable summer season.

WATER
CONSERVATION
SOURCE WATER ASSESSMENT
MEASURES
In 2013, the Massapequa Water District continued to implement a water conservation program in order to minimize
any unnecessary water use. The pumpage for 2013 was only
4.0 percent more than in 2012. This increase can most likely
be attributed to the slightly hotter and drier weather during
2013.
The NYSDOH, with assistance from the local health department, has completed a
source water assessment for this system, based on available information. Possible and
actual threats to this drinking water source were evaluated. The source water assessment includes a susceptibility rating based on the risk posed by each potential source
of contamination and how rapidly contaminants can move through the subsurface to
the wells. The susceptibility of a water supply well to contamination is dependent upon
both the presence of potential sources of contamination within the well’s contributing
area and the likelihood that the contaminant can travel through the environment to
reach the well. The susceptibility rating is an estimate of the potential for contamination of the source water, it does not mean that the water delivered to consumers is, or
will become contaminated. See the section entitled “Water Quality” for a list of the
contaminants
that have been detected. TheJoseph

CONTACTS FOR ADDITIONAL INFORMATION
If you have any questions about this report, concerning the Massapequa
Water District or your water supply, please contact the Water District Superintendent Stan Carey at (516) 798-5266 or the Nassau County Department of Health at (516) 227-9692. You may also want to visit our
website at www.massapequawater.com. We want our valued customers
to be informed about our water system. If you want to learn more, please
attend any of our regularly scheduled meetings. They are normally held on
Wednesday afternoon at 4:00 p.m. at the Water District office.
The Massapequa Water District routinely monitors for different parameters and contaminants in your drinking water as required by Federal and
State laws. All drinking water, including bottled drinking water, may be
reasonably expected to contain at least small amounts of some constituents. It is important to remember that the presence of these constituents
does not necessarily pose a health risk. For more information on contamination and potential health risks, please contact the USEPA Safe Drinking
Water Hotline at 1-800-426-4791 or www.epa.gov/safewater.
During 2014, the District collected 30 samples for lead and copper. The
next round of samples will occur in 2017. If present, elevated levels of
lead can cause serious health problems, especially for pregnant women,
infants, and young children. It is possible that lead levels at your home
WATER CONSERVATION MEASURES
In 2015, the Massapequa Water District continued to implement a
water conservation program in order to minimize any unnecessary
water use. The pumpage for 2015 was only 5.5 percent more than
in 2014. This increase can most likely be attributed to the slightly
hotter and drier weather during 2015.
Residents of the District can also implement their own water conservation measures such as retrofitting plumbing fixtures with flow
restrictors, modifying automatic lawn sprinklers to include rain
sensors, repairing leaks in the home, installing water conservation
fixtures/appliances and maintaining a daily awareness of water
conservation in their personal habits. Residents can pick up water conservation kits at the District office. In addition, consumers
should be aware that the Nassau County Lawn Sprinkler Regulations are still in effect. This includes the ODD/EVEN day limitation and no irrigation between the hours of 10:00 a.m. and 4:00
p.m. Besides protecting our precious underground water supply,
water conservation will produce a cost savings to the consumer
in terms of both water and energy bills (hot water). Utilizing the
water conservation measures listed above can reduce your water
use by up to 5%.
may be higher than at other homes in the community as a result of materials used in
your home’s plumbing. Massapequa Water District is responsible for providing high
quality drinking water, but cannot control the variety of materials used in plumbing
components. When your water has been sitting for several hours, you can minimize the
potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using
water for drinking or cooking. If you are concerned about lead in your water, you may
wish to have your water tested. Information on lead in drinking water, testing methods,
and steps you can take to minimize exposure is available from the Safe Drinking Water
Hotline (1-800-426-4791) or at http://www.epa.gov/safewater/lead.
Some people may be more vulnerable to disease causing microorganisms or pathogens
in drinking water than the general population. Immuno-compromised persons such
as persons with cancer undergoing chemotherapy, persons who have undergone organ
transplants, people with HIV/AIDS or other immune system disorders, some elderly,
and infants can be particularly at risk from infections. These people should seek advice from their health care provider about their drinking water. EPA/CDC guidelines
on appropriate means to lessen the risk of infection by Cryptosporidium, Giardia and
other microbial pathogens are available from the Safe Drinking Water Hotline (800426-4791).
ARE THERE CONTAMINANTS IN OUR
DRINKING WATER?
The natural geology of Long Island’s south shore in areas like Massapequa contain significant
amounts of minerals that result in naturally occurring elevated levels of iron in the water. The
District adds iron sequestering agents (long chain polyphosphates) at all wells as part of the
District’s overall water treatment program to supplement corrosion control and to maintain
the iron in the soluble state to minimize water stains on laundry and plumbing fixtures. The
District continues to monitor the iron levels. Since the levels are approaching regulatory requirements for iron sequestering, the District has begun the design of an iron removal system
and plans to proceed with the installation of system within the next year. In accordance with
State regulations, the Massapequa Water District routinely monitors your drinking water for
numerous parameters. We test your drinking water for coliform bacteria, turbidity, inorganic
contaminants, lead and copper, nitrate, volatile organic contaminants, total trihalomethanes
and synthetic organic contaminants. Over 135 separate parameters are tested for in each of
our wells numerous times per year. The table presented on page 3 depicts which parameters
or contaminants were detected in your drinking water. It should be noted that many of these
parameters are naturally found in some Long Island drinking water and do not pose any adverse health affects.
Groundwater contamination for organic compounds has been a critical issue in Nassau County. Massapequa Water District is one of the last water suppliers in the County that does not
have to treat their water due to groundwater contamination.
SOURCE WATER ASSESSMENT
The NYSDOH, with assistance from the local health department, has completed a source water assessment for this system, based on available information. Possible
and actual threats to this drinking water source were evaluated. The source water assessment includes a susceptibility rating based on the risk posed by each potential
source of contamination and how rapidly contaminants can move through the subsurface to the wells. The susceptibility of a water supply well to contamination
is dependent upon both the presence of potential sources of contamination within the well’s contributing area and the likelihood that the contaminant can travel
through the environment to reach the well. The susceptibility rating is an estimate of the potential for contamination of the source water, it does not mean that the
water delivered to consumers is, or will become contaminated. See the section entitled “Water Quality” for a list of the contaminants that have been detected. The
source water assessments provide resource managers with additional information for protecting source waters into the future.
Our drinking water is derived from nine (9) wells. The source water assessment has rated most of the wells as having a medium high to very high susceptibility to
industrial solvents and a high susceptibility to nitrates. The elevated susceptibility to industrial solvents is due primarily to point sources of contamination related to
transportation routes and commercial/industrial facilities and related activities in the assessment area. The high susceptibility to nitrate contamination is attributable
to residential, commercial and institutional land use and related practices in the assessment area, such as fertilizing lawns.
A copy of the assessment, including a map of the assessment area, can be obtained by contacting the Water District.

Definitions:
Maximum Contaminant Level (MCL) - The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible.
Maximum Contaminant Level Goal (MCLG) - The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a
margin of safety.
Action Level (AL) - The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
Milligrams per liter (mg/l) - Corresponds to one part of liquid in one million parts of liquid (parts per million - ppm).
Micrograms per liter (ug/l) - Corresponds to one part of liquid in one billion parts of liquid (parts per billion - ppb).
Non-Detects (ND) - Laboratory analysis indicates that the constituent is not present.
pCi/L - pico Curies per Liter is a measure of radioactivity in water.
(1)
- During 2014, we collected and analyzed 30 samples for lead and copper. The 90% percentile level is presented in the table. The action level for lead was not exceeded
at any site tested. The next round of sampling and testing will occur in 2017. 90th Percentile Value: The values reported for lead and copper represent the 90th percentile.
A percentile is a value on a scale of 100 that indicates the percent of a distribution that is equal to or below it. The 90th percentile is equal to or greater than 90% of the lead
and copper values detected at your water system.
(2)
- No MCL has been established for sodium. However, 20 mg/l is a recommended guideline for people on high restricted sodium diets and 270 mg/l for those on moderate sodium diets.
(3)
- Iron is only a secondary water standard. Iron has no health effects. Therefore, exceeding the MCL represents a level at which adverse aesthetics effects start to occur.
(4)
- MCL is for Combined Radium 226 & 228.
(5)
- UCMR3 - Unregulated Contaminant Monitoring Rule 3 is a Federal water quality sampling program where water suppliers sample and test their source water for 1 year.
Results will be used by the USEPA to determine if the contaminants need to be regulated in the future.

Massapequa Superintendent Receives
State Award
Massapequa Water District
Training Center
Girl Scout Troop # 2069 recently visited the
Massapequa Water District Training Center to learn
about water conservation and where our water
comes from.
Officals of NYS AWWA present Superintendent
Carey with the Award in Saratoga Springs NY
Superintendent Stan Carey received an award for Service
to the Water Industry from the New York Section of the
American Water Works Association.
Stan has 30 years of experience in the water industry and has
been Superintendent of the Massapequa Water District since
2010. He continues to be extremely active in protecting the
water quality for Massapequa residents from the Bethpage
groundwater plume.
Serving as 1st Vice Chairman of the Long Island Water
Conference (LIWC) and as a Board member for the Long Island Commission for Aquifer Protection (LICAP), Stan has
proven his dedication to keeping Long Island water clean.
On behalf of the Massapequa Water District, congratulations to Superintendent Carey for receiving the Service to
Water Profession Award.
Backflow Testing
Important.....And it’s the Law
The Cadets of Girl Scout Troop # 2069 work on their water project during a visit to Massapequa Water District
educational site.
Pressure Vacuum Breaker - (PVB)
If you have an automatic lawn sprinkling system, a double check valve
or Pressure Vacuum breaker is required by public health law of the
New York state and Sanitary Code 5-1.31, mandating that backfl ows
be tested annually. This piece of equipment is needed because there is
a connection between potable water and possible sources of contamination. For example, a serious fire fighting effort could result in a sudden drop in water pressure. This could cause puddled water around
the sprinkler heads to be pulled back into the system, thus carrying
lawn chemicals into the water supply. A double check valve would
automatically prevent the back siphonage of any water.
Double Check Valve - (DVC)
For the protection of your water source and your neighbors, the law requires these devices to be tested annually by a New York
state-certified tester and the results forwarded to the Water District. If your device is due for a test you will be contacted by District
personnel.
The District provides free backflow testing to all of its residential customers. We appreciate your cooperation with this mandated
regulation.
