1999 DRINKING WATER QUALITY REPORT for BARTONVILLE WATER SUPPLY CORPORATION
Bartonville Water Supply Corporation (BWSC) is pleased to present our 1999 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.
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.
BWSC's current water sources
consist of ten (10) wells that are often referred to as ground (below the surface)
water and water we purchase from the Upper Trinity Regional Water District (UTRWD).
UTRWD’s water comes from lakes and goes through an extensive treatment process
prior to distribution to its customers. BWSC principally provides water service
to 1,785 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.
BWSC'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 completed with 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 BWSC 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
meetings. Unless rescheduled, the Board of Directors meetings are held at 7:00
p.m. on the third 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.

SPECIAL NOTICE FOR THE ELDERLY, INFANTS, CANCER PATIENTS, PEOPLE WITH HIV/AIDS OR OTHER IMMUNE PROBLEMS
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 PERSON 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 at
(800) 426-4791, the Texas Department of Health, or your local Health Department
or District.
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 contaminants or 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 that 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’s important to remember that the presence of these constituents does not necessarily indicate that the water poses a health risk. Maximum Contaminant Levels (MCL's) are set at very stringent levels. To understand the possible health effects described for many regulated constituents, a person would need to drink two (2) liters of water everyday at the MCL level for a lifetime to have a one-in-a-million chance of having the described health effect. Many secondary constituents (such as calcium, sodium, or iron) that are often found in drinking water can cause taste, color, and odor problems. These constituents are not causes for health concerns. Therefore, secondary constituents are not required for this report. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline at (800) 426-4791. BWSC routinely monitors the 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 1, 1999 through December 31, 1999. In the following table you will find many terms and abbreviations that might be unfamiliar to you. To help you better understand these terms, we've 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.

*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.

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.
Bartonville Water Supply Corporation is committed to excellence in all that we do. Now and in the future, the Board of Directors and Staff will continue to strive for excellence in water quality and service. We endeavor to produce superior results and ask that our members help us protect our water sources, which are the heart of our community, our way of life, and our children’s future. If there are any questions pertaining to this report or the BWSC system, please contact the office at (817) 430-3541.
