1998 Consumer Confidence Report
1998
DRINKING WATER QUALITY REPORT
for
BARTONVILLE WATER SUPPLY CORPORATION
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.
Your Drinking Water Is Safe
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 also go to our web site at www.bartonvillewater.com
for more information.
Health Related Issues
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
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.
Assurance of Quality In Our Drinking
Water
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 WSC's Well and Surface
Water Constituents
Detected For 1994 - 1998
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.

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 WSC: Planning Ahead
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. For additional news and information
you can visit us on the World Wide Web at www.bartonvillewater.com .
