Newnan Utilities’ water department has always upheld a strong commitment to providing the very best drinking water to our customers. As part of the effort to supply clean, safe, and reliable water, this report will serve to inform our customers about where our water comes from, what it contains, and how it compares to standards set by state and federal regulatory agencies. For any questions concerning this report or any water quality issues, contact George Lee, Water Treatment Operations Manager at 770-683-5516.

All of our source water is surface water (streams and lakes). It is pumped from Line Creek, Sandy and Brown Creek, and White Oak Creek into the storage reservoirs adjacent to the treatment plant. Our storage capacity is approximately 2 billion gallons. The watershed area is fenced and patrolled to prevent activities which might contaminate our sources.

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 EPA’s Safe Drinking Water Hotline at 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 microbial contaminants are available from Safe Drinking Water Hotline at 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 human activity,

Contaminants that may be present in source water include the following:

  1. Microbial Contaminants, such as viruses and bacteria
  2. Inorganic Contaminants, such as salts and metals
  3. Pesticides and Herbicides
  4. Organic Chemicals, such as synthetic solvents and petroleum
  5. Radioactive Compounds

In order to ensure that tap water is safe to drink, the EPA prescribes regulations that limit the amount of certain contaminants in water provided by public water systems. Newnan’s water is currently tested for over 170 contaminants as part of a on-going monitoring plan.

The table above shows all of the contaminants that were detected during the 2019 calendar year. The presence of these contaminants does not indicate a health risk. The following definitions will aid in interpreting the table

Maximum Contaminant Level (MCL) - The highest level of a contaminant that is allowed in drinking water. MCL's are set as close to the MCLG's as feasible using the best available treatment technology.

Maximum Contaminant Level Goal (MCLG) - The level of a contaminant in drinking water below which there is no known or expected health risk. MCLG's allow for a margin of safety.

Treatment Technique (TT) - A required process intended to reduce the level of a contaminant in drinking water.

Action Level (AL) - The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.

N.T.U. - Nephelometric Turbidity Units are used to measure the clarity of water.

PPM - Parts Per Million, (1 in 1,000,000)

PPB - Parts Per Billion, (1 in 1,000,000,000)
