This Notification of Violation Was Published on September

This notification of violation was published on September 5, 2019. The previous notification had a typographical error for the HAA5 averaged LRAA. At the time of this notification the LRAA was 0.0538 mg/L (not 53.78 mg/L as previously noted). On August 26, 2019, the Department of Watershed Management (DWM) received a Notice of Violation from the Georgia Environmental Protection Division. DWM was notified that the water system recently violated a drinking water standard. Although this is not an emergency, you, as our customers, have a right to know what happened, what you should do, and what we are doing to correct this situation. We are required to monitor your drinking water for the presence of disinfection byproducts (DBPs) on a quarterly basis. The DBPs test results from the last four (4) quarters that ended on June, 2019 show that our system exceeds the standards, or maximum contaminant level (MCLs) for Total Haloacetic Acids (HAA5). MCLs for HAA5 is calculated based on locational running annual averages (LRAA) of samples collected from the last four (4) quarters. The LRAA of HAA5 at 850 Mt. Vernon Highway NW is at 0.069 milligrams per liter (mg/L). This value exceeded the respective MCL for HAA5 of 0.060 mg/L during the monitoring period. It should be noted that this site (# 509) was resampled for DBPs in July for the third (3) quarter 2019, and the HAA5 averaged LRAA was 0.0538 mg/L. Therefore, this site came back into compliance on July 24, 2019 (date sample collected). Violation ID 2019-12632 Compliance Period 2Q2019 04/01/2019 - 06/30/2019 Site # 509 Analyte HAA5 Concentration 0.069 mg/L MCL 0.060 mg/L What should I do? There is nothing you need to do at this time. This violation has been resolved and does not pose a threat to the quality of the water supplied. You do not need to boil your water or take other corrective actions. Residents should not be alarmed and do not need to seek alternative water supplies. The supplier is taking corrective actions to ensure that adequate monitoring and reporting will be maintained. Some people who drink water containing HAA5 in excess of the maximum contaminant level (MCL) over many years, experience problems with their liver, kidneys, or central nervous system, and may have an increased risk of getting cancer. If you have a severely compromised immune system, have an infant, are pregnant, or are elderly, you may be at increased risk and should seek advice from your health care providers about drinking this water. What happened? What is being done? When disinfectants are used in the treatment of drinking water, disinfectants react with naturally occurring organic and inorganic matter present in water to form disinfection byproducts (DBPs). DWM has taken the following corrective actions: When informed of the increased levels from the first quarter 2019 sampling event, DWM quickly began an enhanced flushing program to decrease the age and temperature of the water in the system, especially in low use areas. Increased flushing will continue until such time that sampling indicates DBP concentrations are below the acceptable limit. Additionally, DWM has engaged engineers to develop recommendations for any corrective measures. If you have any questions, please contact Paul Moisan at 404-546-1232, or at 72 Marietta Street NW, Atlanta, GA 30303. *Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail. 9/22/19
