2021 Annual Drinking Water Quality Report
City of Louisville & City of Louisville-Northeast
PWS ID # 0800004 & 0800005
May 2022
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 6 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, 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 2nd 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 1st to December 31, 2021. 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”, 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 12. 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%.

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.
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. 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).
This report is being published in the paper and will not be mailed. Please call our office if you have any questions.
