Town of Exmore INTRODUCTION This Annual Drinking Water Quality Report for calendar
year 2005 is designed to inform you about your drinking water quality. Our goal
is to provide you with a safe and dependable supply of drinking water, and we
want you to understand the efforts we make to protect your water supply. The
quality of your drinking water must meet state and federal requirements
administered by the Virginia Department of Health (VDH). If you have questions about this report, please contact: Herbert Gilsdorf, Town Manager (757) 442-3114 ext. 13 If you want additional information about any aspect of your drinking water or want to know how to participate in decisions that may affect the quality of your drinking water, please contact: Town Office (757) 442-3114
The times and
location of regularly scheduled Council meetings are as follows: Town Hall 3305 Main
Street, 7:00 P.M. First Monday of the month GENERAL INFORMATION 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.
Substances (referred to as contaminants) in source water may come from septic
systems, discharges from domestic or industrial wastewater treatment
facilities, agricultural and farming activities, urban storm water runoff,
residential uses, and many other types of activities. Water from surface
sources is treated to make it drinkable while groundwater mayor may not have
any treatment.
All drinking water, including bottled drinking 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 information can be obtained by calling the
Environmental Protection Agency's Safe Drinking Water Hotline (800-426-4791).
Some people may be more vulnerable to contaminants in
drinking water than the general population. Immunocompromised 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 about drinking water from their health care providers. EPA/CDC
guidelines on appropriate means to lessen the risk of infection by Cryptosporidium
and other microbiological contaminants are available from the Safe Drinking
Water Hotline (800-426-4791).
SOURCE (S) and TREATMENT OF YOUR DRINKING WATER
The source of your drinking water is (x) groundwater as described below:
The Town of Exmore receives its water from two wells
located on Route 687 and Route 693. The well depths are 200 feet and 212 feet
deep and are screened at 160 feet to 200 feet.
The Virginia Department of
Health conducted a Source Water Assessment of the Central System in 2002. Some
wells were determined to be of high susceptibility to contamination using the
criteria developed by the state in its approved Source Water Assessment Program.
The assessment report consists of maps showing the source Water Assessment
area, an inventory of known Land Use Activities and Potential Source of
contamination, susceptibility Explanation Chart, and Definitions of Key Terms. DEFINITIONS Contaminants in your drinking water are routinely
monitored according to Federal and State regulations. The table on the next
page shows the results of our monitoring for the period of January 1st
to December 31st, 2005. In the table and elsewhere in this report
you will find many terms and abbreviations you might not be familiar with. The
following definitions are provided to help you better understand these terms:
Non-detect (ND)
lab analysis indicates that the contaminant is not present 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. Parts per trillion
(ppt) or Nanograms per liter (nanograms/I) one part per
trillion corresponds to one minute in 2,000,000 years, or a single penny in
$10,000,000,000. Picocuries per
liter (pCi/L) picocuries per liter is a measure of the
radioactivity in water. 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. Action Level the concentration of a contaminant which, if exceeded, triggers
treatment or other requirements which a water system must follow. Treatment Technique
(TT) a required process intended to reduce the level of a
contaminant in drinking water. Maximum Contaminant
Level, or MCL 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, or 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. Variances
and, exemptions state or EP A permission not to meet an MCL or a
treatment technique under certain conditions MRDL
or Maximum Residual Disinfectant Level
_ means the highest level of a disinfectant allowed in drinking water. There is
convincing evidence that addition of a disinfectant is necessary for control of
microbial contaminants. MRDLG
or Maximum Residual Disinfectant Level Goal _ means 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.
ppm= Parts
per Million, ppb= Parts per
billion, pCi/L= Picocuries
per liter, ND= Non-Detect
* One in ten lead samples reported in 2005 was above the
action level. Most of the results in the table are from testing done
in 2005. However, the state allows us to monitor for some contaminants less
than once per year because the concentrations of these contaminants do not
change frequently. Some of our data, though accurate, is more than one year
old. MCL's are set at very stringent levels by the U.S.
Environmental Protection Agency. In developing the standards EP A assumes that
the average adult drinks 2 liters of water each day throughout a 70-year life
span. EP A generally sets MCLs at levels that will result in no adverse health
effects for some contaminants or a one-in-ten-thousand to one-in-a-million
chance of having the described health effect for other contaminants.
VIOLATION
INFORMATION Did any MCL or TT violations occur during
the year? (
) Yes ( X) No Did any monitoring, reporting, or other
violations occur during the year? ( ) Yes (
X) No
Future problems, however minor, will be
reported to you as part of Federal (EPA) and State Regulations aimed at
increasing consumer awareness of conditions that exist in the waterworks. ADDITIONAL HEALTH INFORMATION Certain contaminants (such as Cryptosporidium,
radon, arsenic, nitrate, and lead), if present in your drinking water, may be
of special concern to consumers. Are any of those contaminants present at
levels of concern that must be reported to you? Infants and children who drink water which contains
lead in excess of the action level could. Experience delays in their physical
or mental development. Children could show slight deficits in attention span
and learning abilities. Adults who drink this water over many years could
develop kidney problems or high blood pressure.
