Annual Drinking Water Quality Report
City of Louisville & City of Louisville-Northeast
PWS ID # 0800004 & 0800005
April, 2015
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 consists of a total of six wells that draw from the
Lower Wilcox Aquifer.
A source water assessment has been completed for the water
supply to determine the overall susceptibility of its drinking water to
identify potential sources of contamination.. The water supply for the City of Louisville and the City of Louisville- Northeast received a moderate
susceptibility ranking to contamination.
We’re pleased to report that our drinking water meets all
federal and state requirements.
If you have any questions about this report or concerning
your water utility, please contact Wilson Webb at 662-773-7147 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 meetings. They are held on
the second Monday of each month at Louisville Utilities office at 8:00 a.m.
The City of Louisville
and Louisville-Northeast routinely monitors for constituents 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,
2014. 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 constituents. It's important to
remember that the presence of these constituents 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:
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 treatment technique is a
required process intended to reduce the level of a contaminant in drinking
water.
Maximum Contaminant 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.

To comply with the “Regulation Governing Fluoridation of
Community Water Supplies”, CITY OF LOUISVILLE
is required to report certain results pertaining to fluoridation of our water
system. The number of months in the
previous calendar year in which average fluoride sample results were within the
optimal range of 0.7-1.3 ppm was 11. The percentage of fluoride samples
collected in the previous calendar year that was within the optimal range of
0.7-1.3 was 93%.

Additional
Information for Lead
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 City of Louisville and Louisville-Northeast 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 or at http://www.epa.gov/safewater/lead.
The Mississippi State Department of Health Public Health Laboratory offers lead
testing for $10 per sample. Please contact 601.576.7582 if you wish to have
your water tested..
All sources of drinking water are subject to potential
contamination by substances that are naturally occurring or man made. These
substances can be microbes, inorganic or organic chemicals and radioactive
substances. All 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 the 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 at 1-800-426-4791.
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).
