The U.S. Environmental Protection Agency (EPA) selected the City of Savannah to participate in the Unregulated Contaminant Monitoring Regulation 3 (UCMR 3) program. Unregulated contaminants are those for which EPA has not established drinking water standards. The purpose of unregulated contaminant monitoring is to assist EPA in determining the occurrence of unregulated contaminants in drinking water and whether future regulation is warranted.
Unregulated contaminants were last sampled in 2020.
All sources of drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some substances. All water sources are fed by water that passes over the land or through the ground, dissolving naturally occurring minerals and materials, or picking up substances along the way. These substances may include:
If you have any questions regarding safe drinking water regulations or these test results, you may contact the City of Savannah Water Supply and Treatment Department at (912) 964-0698.
Health Information
Some people may be more vulnerable to contaminants in drinking water than the general population. Immune-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 healthcare providers.
EPA/Center for Disease control guidelines on appropriate means to lessen the risks of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline at 1-800-426-4791
Exposure to lead in drinking water can cause serious health effects in all age groups. Infants and children can have decreases in IQ and attention span. Lead exposure can lead to new learning and behavior problems or exacerbate existing learning and behavior problems. The children of women who are exposed to lead before or during pregnancy can have increased risk of these adverse health effects. Adults can have increased risks of heart disease, high blood pressure, kidney or nervous system problems.
The City of Savannah is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing fixtures. 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 have concerns 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 at 1-800-426-4791 or at www.epa.gov/safewater/lead. Information is also available on our Water & Lead page.
