2009 Annual Drinking Water
Quality
Town of Burnsville
PWSID: 01-00-010
JUNE
2010
We're
pleased to present to you this year's Annual Water Quality Report. This
report
is designed to inform you about the quality water and 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 water.
Our water source is drawn
from Bowlens Creek, surface water and Cane River, surface water.
Raw
water from Bowlens Creek
and Cane River is treated at the Town of Burnsville Water Plant. The treatment process has four main steps: coagulation, sedimentation, filtration, and
disinfection. First, chemicals are mixed
into the water which form a solid material around small particles in the
raw
water, causing them to clump together.
The particles are allowed to settle to the bottom of large
settling
tanks and then removed. The water flows
through filters of carbon and sand to remove any remaining particles. Finally chlorine is added to disinfect and
to ensure that the water is safe to drink when it reaches the customers.
I'm pleased to report that our drinking water
is safe and meets all
federal and state requirements.
If you have any questions
about this report or concerning your water utility, please contact Thomas W. Storie at (828) 682-2420. We want our valued customers to be informed about
their water utility. If you want to learn more, please attend any of our
regularly scheduled board meetings. Our
board meetings are held on the first Thursday of each month at 6:00 PM.
in the Town
Hall.
What EPA Wants
You to Know
Drinking
water, including bottled 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
about
contaminants and potential health effects 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. Immuno-compromised 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).
The
sources of drinking water (both tap water and bottled 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, radioactive material, and can pick up
substances
resulting from the presence of animals or from human activity.
Contaminants
that may be present in source water include microbial contaminants,
such
as viruses and bacteria, which may come from sewage treatment plants,
septic
systems, agricultural livestock operations, and wildlife; inorganic
contaminants, such as salts and metals, which can be
naturally-occurring or
result from urban storm water runoff, industrial or domestic wastewater
discharges,
oil and gas production, mining, or farming; pesticides and herbicides,
which may come from a variety of sources such as agriculture, urban
storm water
runoff, and residential uses; organic chemical contaminants,
including
synthetic and volatile organic chemicals, which are by-products of
industrial
processes and petroleum production, and can also come from gas stations,
urban
storm water runoff, and septic systems; and radioactive contaminants,
which can be naturally-occurring or be the result of oil and gas
production and
mining activities.
“If
present, elevated levels of lead can cause serious health problems,
especially
for pregnant women and young children.
Lead in drinking water is primarily from materials and components
associated with service lines and home plumbing. The
Town of Burnsville is responsible for
providing high quality drinking water, but cannot control the variety of
materials used in plumbing components.
When your water has been sitting for several hours, you can
minimize the
potential 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. Information on lead in
drinking water, testing methods, and steps you can take to minimize
exposure is
available from the Safe Drinking Water Hotline (800-426-4791) or at http://www.epa.gov/safewater/lead.”
In
order to ensure that tap water is safe to drink, EPA prescribes
regulations
which limit the amount of certain contaminants in water provided by
public
water systems. FDA regulations establish limits for contaminants in
bottled
water which must provide the same protection for public health.
Source Water Assessment Program (SWAP) Results
The
North Carolina Department of Environment and Natural Resources (DENR),
Public
Water Supply (PWS) Section, Source Water Assessment Program (SWAP)
conducted
assessments for all drinking water sources across North Carolina. The purpose of the assessments was to
determine the susceptibility of each drinking water source (well or
surface
water intake) to Potential Contaminant Sources (PCSs).
The results of the assessment are available
in SWAP Assessment Reports that include maps, background information and
a
relative susceptibility rating of Higher, Moderate or Lower.
The
relative susceptibility
rating of each source for Town of Burnsville was determined by combining
the
contaminant rating (number and location of PCSs within the assessment
area) and
the inherent vulnerability rating (i.e., characteristics or existing
conditions
of the well or watershed and its delineated assessment area.). The
assessment
findings are summarized in the table below:

It
is important to understand that a susceptibility rating of “higher” does
not
imply poor water quality, only the systems’ potential to become
contaminated by
PCS’s in the assessment area
The Town of Burnsville routinely monitors for contaminants
in your drinking water according to Federal and State laws. This
table shows the results of our
monitoring for the period of January 1st to December 31st,
2009 and the last test results of
contaminants that were
not due to be tested in 2009. As
water travels over the land or underground it can pick up substances or
contaminants such as microbes, inorganic and organic chemicals, and
radioactive
substances. All drinking water,
including bottled drinking water, may be reasonably expected to contain
at
least small amounts of some contaminants.
It's important to remember that the presence of these
contaminants does
not necessarily pose a health risk.
In this
table you will find
many terms and abbreviations you might not be familiar with. To help you
better
understand these terms we've provided the following definitions:
Not-Applicable
(N/A) – Information not applicable/not required for that
particular water system of for that particular Rule.

While your drinking water meets EPA’s standard for
arsenic,
it does contain low levels of arsenic. EPA’s standard balances the
current
understanding of arsenic’s possible health effects against the costs of
removing arsenic from drinking water. EPA continues to research the
health
effects of low levels of arsenic, which is a mineral known to cause
cancer in
humans at high concentrations and is linked to other health effects such
as
skin damage and circulatory problems.

Nitrate in drinking water at levels above 10 ppm is a
health risk for infants of less than six months of age. High nitrate
levels in
drinking water can cause blue baby syndrome. Nitrate levels may rise
quickly
for short periods of time because of rainfall or agricultural activity.
If you
are caring for an infant you should ask advice from your health care
provider.

Infants
and young children
are typically more vulnerable to lead in drinking water than the general
population. It is possible that lead levels at your home may be higher
than at
other homes in the community as a result of materials used in your
home's
plumbing. If you are concerned about elevated lead levels in your home's
water,
you may wish to have your water tested and flush your tap for 30 seconds
to 2
minutes before using tap water. Additional information is available from
the
Safe Drinking Water Hotline (800-426-4791).

Microbiological
Contaminants:
Total
Coliform. Coliforms are bacteria
that are naturally present in the environment and are used as an
indicator that
other, potentially-harmful, bacteria may be present. Coliforms were
found in
more samples than allowed and this was a warning of potential problems.
Fecal
coliform/E.Coli. Fecal coliforms and
E. coli are bacteria whose presence indicates that the water may be
contaminated with human or animal wastes. Microbes in these wastes can
cause short-term
effects, such as diarrhea, cramps, nausea, headaches, or other symptoms.
They
may pose a special health risk for infants, young children, and people
with
severely compromised immune systems.
Turbidity.
Turbidity has no health
effects. However, turbidity can interfere with disinfection and provide a
medium for microbial growth. Turbidity may indicate the presence of
disease-causing organisms. These organisms include bacteria, viruses,
and
parasites that can cause symptoms such as nausea, cramps, diarrhea, and
associated headaches.

IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER SAMPLE
North Carolina’s Rules Governing
Public Water Systems (15A NCAC 18C) require that a public water
system
sample for certain contaminants that may occur in the drinking water
distribution system. For many
contaminants, multiple water samples are necessary to determine a
system’s
compliance with the water quality standards.
Although several sample results may exceed the allowable limits,
the
system may be in compliance based on multiple sample results and will
not be
required to perform system-wide public notification or take corrective
action. However, the consumers of the
drinking water at an individual location where the allowable limits are
exceeded are still susceptible to adverse health effects.
The purpose of this notice is to inform you
of the analytical results for the drinking water sample collected at the
location identified below. Since the
allowable limit was exceeded at this location, the potential health
effects are
also included so you can take any precautionary measures you feel are
necessary
to further protect your health.
