2022 Annual Drinking Water Consumer Confidence Report
City of Louisville & City of Louisville-Northeast
PWS ID # 0800004 & 0800005
Report Completed on May 8, 2023
We're pleased to present to you your 2022 Annual Report. This report is designed to inform you about the quality
water and services we deliver to you every day. Our constant goal isto 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.
Sources of Water
Our water source consists of 6 wells that draw from the Lower Wilcox Aquifer.
Water System Information
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. Our water supply received a moderate susceptibility
ranking to contamination.
This past year we rehabbed one of the four filters in the water plant to increase the iron removal process in the
water and ordered material to completely rehab a second filter that was installed in 2006. We secured a grant and
local funds to change out equipment ahead of the filters to improve water quality and filter run times before
backwash. This money will also be used to harden our water assets that were compromised during winter storm
Elliot late last year. Based on financial reports, 93 cents out of every dollar collected by the water system goes to
water purification or operation and maintenance of the system. We strive to provide safe quality water at an
affordable price.
If you have any questions about this report or concerning your water utility, please contact Wilson Webb, General
Manager 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 2
nd Monday of each month
at 871 South Columbus St. At 8:00 am.
We routinely monitor 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 1
st
to December 31, 2022. 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.

Fluoride Information
To comply with the “Regulation Governing Fluoridation of Community Water Supplies”, the 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 the average fluoride sample results were within the optimal range of 0.6 - 1.2 ppm
was 11. The percentage of fluoride samples collected in the previous calendar year that was within the optimal
range of 0.6 - 1.2 ppm was 100%. The number of months samples were collected and analyzed in the previous
calendar year was 11.

Definitions
In the table above 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.
ppb - parts per billion = micrograms per liter (= 1 drop in 1 billion gallons)
ppm - parts per million = milligrams per liter (= 1 drop in 1 million gallons)
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. Our water system 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. Please contact 601.576.7582 if you wish to have your water tested.
Additional Information
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).
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.
EPA is reviewing the drinking water standard for arsenic because of special concerns that it may not be stringent
enough. Arsenic is a naturally occurring mineral known to cause cancer in humans at high concentrations.

The average household uses approximately 400 gallons of water per day. There are many low cost and no-cost
ways to conserve water. Small changes can make a big difference - try one today and soon it will become second
nature.
W Take short showers - a 5 minute shower uses 4 to 5 gallons of water compared to 50 gallons for a bath.
W Shut off water while brushing your teeth, washing your hair and shaving and save up to 500 gallons a month.
W Use a water-efficient showerhead. They are inexpensive, easy to install and can save you up to 750 gallons a
month.
W Run your clothes wash and dishwasher only when they are full. You can save up to 1,000 gallons a month.
W Water plants only when necessary.
W Fix leaky toilets and faucets. Faucet washers are inexpensive and take only a few minutes to replace. To
checks your toilet for a leak, place a few drops of food coloring in the tank and wait. If it seeps into the
toilet bowl without flushing, you have a leak. Fixing it or replacing it with a new, more efficient model can
save up to 1,000 gallons a month.
W Adjust sprinklers so only your lawn is watered. Apply water only as fast as the soil can absorb it and during the
cooler parts of the day to reduce evaporation.
W Teach your children about water conservation to ensure a future generation that uses water wisely. Make it a
family effort to reduce next month’s water bill!
