The Georgia EPD has cited the city of Summerville for a drinking water violation that occurred between April 1, 2018 and June 30, 2018.
The city received the violation for having higher than normal levels of haloacetic acids in water lines through its system. Following the Safe Drinking Water Act Amendments of 1996, EPA set standards for HAA5 in a series of regulations (Disinfection Byproducts Rule Stage 1 and 2). The federal enforceable standard for HAA5 is a maximum running annual average for each monitoring location of 60 micrograms/liter, Summerville’s water tested above the limit.
According to DrinkTap.org
Haloacetic acids (HAA5, HAA6Br, HAA9) are a group of disinfectant byproducts that are formed when disinfectants, such as chlorine or chloramine, are used to treat water and react with naturally occurring organic and inorganic matter present in source waters. Which HAA forms depends on several factors, so HAAs are often tracked and described as groups of individual acidic compounds. As more HAAs are included in one of these groupings, the list of compounds that contain bromide increases:
- HAA5 includes: dibromoacetic acid, dichloroacetic acid, monobromoacetic acid, monochloroacetic acid, trichloroacetic acid
- HAA6Br includes: bromochloroacetic acid, bromodichloroacetic acid, dibromoacetic acid, chlorodibromoacetic acid, monobromoacetic acid, tribromoacetic acid
- HAA9 includes: bromochloroacetic acid, bromodichloroacetic acid, chlorodibromoacetic acid, dibromoacetic acid, dichloroacetic acid, monobromoacetic acid, monochloroacetic acid, tribromoacetic acid, trichloroacetic acid
