City of Grantville 2021 CCR 2021 Consumer Confidence Report City of Grantville- - Water system ID - Ga0 0770001  CityofGrantville, Water department Phone 770-583-2289  Special Information  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. City of Grantville 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  nttp//www.epa.ov/salewater/lead. IMMINO-COMIPROMISEDLANGUAGE  Some people may be more vulnerable to contaminants in drinking water than the general population. mmuno.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. EPNCDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (1-800- 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 the EPA's SOURCES OF DRINKING WATER AND] PRESENCE OF CONTAMINANTS LANGUAGE 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 ori from human activity. Contaminants that may be present in: source water include the following:  426-4791)  DRINKINGAND BOTTLEDWATER LANGUAGE Safe Drinking Water Hotline (*800-426-4791)  Microbial contaminants, such as viruses and bacteria which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife. Inorganic contaminants such as salts and metals, which can be naturally occurring or result from urban storm runoff, industrial or domestic wastewater discharges, oil and gas Pesticides and herbicides, which may come from a variety of sources such as agriculture, Organic chemical contaminants, including syntheticand volatile organic chemicals, which are by: products of industrial processes and petroleum production, and can also come from gas Radioactive contaminants, which can be naturally occurring or be the result of oil and gas  production, mining, or fanning. urban stormwater runoff, and residential uses. stations, urban stormwater runoff, and septicsystems.  production and miningactivities.  In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the number of certain  Page 1of3    City of Grantville 2021 CCR  contaminants in water provided by public water systems. Food and Drug Administration regulations establish limits for contaminants in bottled water which must provide the same protection for public health. This report details information on our water system for the calendar year 2021 unless otherwise noted. We are required to monitor for certain parameters less than once per year because the concentration is not expected to vary significantly from one year to the next. Therefore, some oft the data int this report is more than one year old. Summary Water System Information: The system sent in 48 microbiological routine samples with 481 negative and 0 positive for coli form and 0 positive for Total Coliform. All samples were received by the lab in at timely manner. The city  receives all water: from Coweta County.
