2014 Water Quality Report Water tes ng performed in 2013 PWS ID #KY0050929 Water Quality Report Barren River Reservoir Water Treatment Plant, Lucas KY We are pleased to present the 2014 Water Quality Report. This report is designed to inform the public about the quality of water and services provided on a daily basis. The Glasgow Water Company (GWC) maintains its own water quality tes ng laboratories. The experienced and cer fied water quality personnel analyze chemical and bacteriological tests on water samples throughout the year. These samples are taken from each sec on of the treatment process as well as from various sites within the distribu on system. The tests are analyzed 365 days a year to assure water safety and quality. We would like the public to be assured that we will con nue to monitor, improve, and protect the water system and deliver a high quality product direct to the tap. Water is the most indispensable product in every home, and we ask everyone to be conserva ve and help us in our efforts to protect the water source. Presently the GWC is the 13th largest water u lity in the State of Kentucky. The GWC maintains 888 miles of water mains serving over 16,400 water customers and maintains 148 miles of sewer mains serving nearly 5,900 wastewater customers. The GWC also provides wholesale water service to six surrounding u li es including the City of Edmonton, Allen County Water District, Fountain Run Water District, Green River Valley Water District, Caveland Environmental Authority, and Warren County Water District. On average the GWC distributes over 2.7 billion gallons of water and treats 750 million gallons of waste water annually. GWC Water Treatment Plant Opera ons Receives AWOP Award The GWC Water Treatment Plants are 2 of 54 water treatment plants in Kentucky recognized by the Energy and Environment Cabinet - Division of Water for their demonstrated success in producing drinking water that consistently met or exceeded state water quality standards. The 54 systems honored are among 155 public and private water treatment plants in the state that par cipated in the U.S. Environmental Protec on Agency’s Area-Wide Op miza on Program (AWOP). The AWOP program challenges plants to reduce turbidity and disinfec on byproduct levels below those required by state and federal regulaons. The program goals are three mes as strict as federal requirements for the same cons tuents. Both GWC water treatment plants, Barren River Reservoir WTP and Beaver Creek WTP, are classified as a “Totally Op mized Plant” for turbidity and microbial removal and received the AWOP award. The GWC has received this recogni on the past five consecu ve years. NOTICE: Important Informa on water than the general popula on. Immuno-compromised persons Pay your such as persons with cancer undergoing chemotherapy, persons who Water Bill Some people may be more vulnerable to contaminants in drinking have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be par cularly at risk from infec ons. These people should seek advice about drink- ONLINE ing water from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infec on by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline 800-426-4791.

Water Source Informa on Water Quality Data The GWC operates two water treatment plants, both trea ng surface water. They are the Barren River Reservoir Water Treatment Plant (A) located in Lucas, and the Beaver Creek Water Treatment Plant (B) located north of Glasgow. The Barren River Reservoir Water Treatment Plant’s raw water source is Barren River Lake while the Beaver Creek Water Treatment Plant draws raw water from Beaver Creek. The water from both plants blend together in the distribu on system and serves customers in Glasgow, Barren County, and Allen County. In addi on, the GWC wholesales water to six surrounding u li es. In the Water Quality Data Table, you may find terms or abbreviaons that are unfamiliar. To help you be er understand the results, the following defini ons are provided. Some or all of these definions may be found in this report: A source water assessment has been completed. The Barren River Lake has one KPDES permi ed discharger, an under-ground storage tank, agricultural chemical users and oil and gas wells that could be possible sources of contamina on. The Beaver Creek Plant has two bridges, several oil and gas wells, one KPDES permi ed discharger, an underground storage tank and agricultural chemical users upstream and in proximity of its intake. The final source water assessment with the system’s suscep bility to poten al sources of contamina on is available for review at the Barren River Area Development District (BRADD) office located at 177 Graham Avenue, Bowling Green, Kentucky. Regulated Contaminants in the Water Supply The sources of drinking water (both tap water and bo led water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioacve material, and may pick up substances resul ng from the presence of animals or from human ac vity. MCL = Maximum Contaminant Level - The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology. MCLG = Maximum Contaminant Level Goal - 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. TT = Treatment Technique - A required process intended to reduce the level of a contaminant in drinking water. AL = Ac on Level - The concentra on of a contaminant which, if exceeded, triggers treatment or other requirements that a water system shall follow. Turbidity = A measure of the clarity of water. Turbidity has no health effects. However, turbidity can provide a medium for microbial growth. Turbidity is monitored because it is a good indicator of the effec veness of the filtra on system. NTU = Nephelometric Turbidity Unit MRDL = Maximum Residual Disinfectant Level - The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addi on of a disinfectant is necessary for control of microbial contaminants. MRDLG = Maximum Residual Disinfectant Level Goal - The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants. In order to ensure that tap water is safe to drink, EPA prescribes regula ons that limit the amount of certain contaminants in water provided by public water systems. FDA regula ons establish limits for contaminants in bo led water to provide the same protec on for public health. BDL = Below Detec on Levels - Laboratory analysis indicates that the contaminant is not present. Drinking water, including bo led water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More informa on about contaminants and poten al health effects may be obtained by calling the Environmental Protecon Agency's Safe Drinking Water Hotline 1-800-426-4791. ppm = Parts per million - Milligrams per liter, (mg/l). Contaminants that may be present in source water include: Microbial Contaminants. Examples include viruses and bacteria that may come from wildlife, agricultural livestock opera ons, sep c systems, and waste water treatment plants. Inorganic Contaminants. Examples include salts and metals, that can be naturally occurring or result from storm water runoff, industrial or domes c wastewater discharges, oil and gas produc on, mining or farming. Pes cides and Herbicides. These may come from a variety of sources such as agriculture, storm water runoff, and residen al use. Organic Chemical Contaminants. These include synthe c and volale organic chemicals, which are by-products of industrial processes and petroleum produc on, and can also come from gas sta ons, storm water runoff, and sep c systems. Radioac ve Contaminants. These can be naturally occurring or be the result of oil and gas produc on and mining ac vi es. Range of Detec on = This is the lowest and highest levels of detecon. N/A = Not Applicable - Does not apply. ppb = Parts per billion - Micrograms per liter, (µg/L). ppt = Parts per trillion - Nanograms per liter, (ng/l) pCi/L = Picocuries per liter - Measure of the radioac vity in water. mrem/yr = Millirems per year - Measure of radia on absorbed by the body. Regulated Contaminant Test Results The data presented in this report are from the most recent tes ng performed in accordance with administra ve regula ons in 401 KAR Chapter 8. As authorized and approved by EPA, the State has reduced monitoring requirements for certain contaminants to less o en than once per year because the concentra ons of these contaminants are not expected to vary significantly from year to year. Some of the data in this table, though representa ve, may be more than one year old. Unless otherwise noted, the report level is the highest level detected. The GWC test for over 100 regulated and unregulated contaminants. The following table summarizes the analy cal results for the 2013 calendar year.

Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. Your local public water system is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been si ng for several hours, you can minimize the poten al 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. Informa on on lead in drinking water, tes ng methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline 1-800-426-4791 or at h p://www.epa.gov/safewater/lead.
