Bartonville Water Supply Corporation is pleased to present you with our 1998 Drinking Water Quality Report. This report is designed to inform you about the quality of your drinking water and the services we deliver to you every day.

Beginning this year and continuing annually, BWSC as well as all other public water systems will be required by the Safe Drinking Water Act to prepare and deliver this report to you.

Our constant goal is to provide you with a safe and dependable supply of drinking water. We want you to understand the efforts we make to continually improve the water treatment process and protect our water resources. We are committed to ensuring the quality of your drinking water.

Bartonville Water Supply Corporation's current water sources consist of ten (10) wells which are often referred to as ground (below the surface) water and water we purchase from the Upper Trinity Regional Water District which is treated surface water from Lake Lewisville. We principally provide water service to 1752 connections in a 20+ square mile area which includes the Towns of Bartonville, Double Oak, Copper Canyon and some unincorporated portions of south central Denton County.

Bartonville Water Supply Corporation's Board of Directors and Staff are pleased to report that our drinking water is safe and meets federal and state requirements. As required by the U.S. EPA, the Texas Commission on Environmental Qualty (TCEQ) has assessed our system and made this determination. The analysis was made by using the data in the attached tables. However, if you have any questions about this report or any other issue concerning your water utility, please contact Jim Leggieri, General Manager of the Bartonville Water Supply Corporation or Tony Mauldin, Water Superintendent for the corporation. They can be reached by calling the office at (817) 430-3541. We want you to be informed about our water quality. If you want to learn more about BWSC, please attend any of our regularly scheduled Board meetings. Unless rescheduled, the Board of Directors meetings are held at 7:00 p.m. on the second Thursday of every month at the office at 1911 E. Jeter Rd. in Bartonville, TX, 76226. All meeting agendas with time and date are posted at the office. If you have questions please call the office at 817-430-3541.

You may be more vulnerable to certain microbial contaminants in drinking water than the general population. In particular, infection by CRYPTOSPORIDIUM is of concern. Infants, some elderly, or IMMUNO-COMPROMISED PERSONS such as those UNDERGOING CHEMOTHERAPY FOR CANCER; those who have undergone ORGAN TRANSPLANTS; those who are undergoing treatment with steroids; and people with HIV/AIDS or other immune system disorders can be particularly at risk from infections. You should seek advice about drinking water from your physician or health care provider. Additional guidelines on appropriate means to lessen the risk of infection by CRYPTOSPORIDIUM are available from the Safe Drinking Water Hotline (1-800-426-4791), the Texas Department of Health, or your local Health Department or District. Please feel free to call our office if you have questions.

Sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. All of these sources, including bottled drinking water, may reasonably be expected to contain at least small amounts of some constituents. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and can pick up substances resulting from the presence of animals or from human activity. In order to insure that tap water is safe to drink, the EPA prescribes regulations which limit the amount of certain substances in water provided by public water systems.

The FDA also regulates bottled water but not as closely as public water supplies. It is important to remember that the presence of these constituents does not necessarily indicate that the water poses a health risk. MCL's (Maximum Contaminant Levels) or constituent levels are set at very stringent levels. To understand the possible health effects described for many regulated constituents, a person would have to drink 2 liters of water every day at the MCL level for a lifetime to have a one-in-a-million chance of having the described health effect. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency's Safe Drinking Water Hotline at 1-800-426-4791.

Bartonville Water Supply Corporation routinely monitors for constituents in your drinking water according to Federal and State laws. The tables in this report show the results of our monitoring in accordance with regulations for the period of January 1st to December 31st, 1994 through 1998.

In the following tables you will find many terms and abbreviations you might not be familiar with. To help you better understand these terms we have provided the following definitions:

EPA- Environmental Protection Agency

FDA- Food and Drug Administration

Parts per million (ppm) or Milligrams per liter (mg/l) - One part per million corresponds to one minute in two years or a single penny in $10,000.

Parts per billion (ppb) or Micrograms per liter - One part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000.

Million Fibers per Liter (MFL) - Million fibers per liter is a measure of the presence of asbestos fibers that are longer than 10 micrometers.

Nephelometric Turbidity Unit (NTU) - Nephelometric turbidity unit is a measure of the clarity of water. Turbidity in excess of 5 NTU is just noticeable to the average person.

Treatment Technique (TT) - A treatment technique is a required process intended to reduce the level of a contaminant in drinking water.

Maximum Contaminant Level or Constituent Level - The "Maximum Allowed" (MCL) is 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.

Maximum Contaminant Level Goal - The "Goal"(MCLG) is 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.

Bartonville Water Supply Corporation's well water and the treated surface water we purchase from the Upper Trinity Regional Water District were each tested for up to 97 possible constituents with no violations noted and only 6 constituents were detected. These are listed in Table I (BWSC) and Table II (UTRWD) on the following pages:

*This detected contaminant appeared temporarily and was most likely the result of the application of new interior surface coatings on ground storage tanks. Such detects are not unusual after this type of work is performed. Follow up testing conducted during the fall of 1998 by the Texas Commission on Environmental Qualty confirmed no detectable traces remaining in our water supply at this time.

*More recent uncertified measurements show an average range of 30-50 ppb.

As you can see from the tables, BWSC's system, using a blend of both well water and purchased treated surface water from the UTRWD, had no violations. We are proud that your drinking water meets or exceeds all Federal and State requirements. We have learned through our monitoring and testing that some constituents have been detected; however, the EPA has determined that your water IS SAFE at these levels.

BWSC will soon complete its most recent phase of capital improvements. These improvements will prepare our water system for the year 2000 and beyond. In addition to miles of new large diameter water mains, elevated and additional ground storage tanks, large capacity pumps, a SCADA (remote monitoring) system and an auxiliary power supply for emergencies, BWSC is also participating in new Upper Trinity Regional Water District projects to ensure adequate treated surface water supplies for now and in the future. We will continue in our efforts to maintain a safe and dependable water supply for you, our BWSC customer.

Bartonville Water Supply Corporation is committed to excellence. Now and in the future, the Board of Directors and Staff will continue to strive for excellence in water quality and in service to you, our customers. We endeavor to produce superior results and ask that you as a customer help us protect our water sources, which are the heart of our community, our way of life and our children's future.
