As a result of this law, the Environmental Protection Agency set drinking water quality standards for all public water systems across the country. These regulations require that all municipal water supplies be treated to limit bacterial growth and other hazardous contaminants. Water treatment companies can choose different disinfectant methods and for a long time chlorine was the disinfectant of choice; however, many municipal water treatment plants have switched to chloramines.
