26 Is My Water pH Neutral? It's possible for water to be acidic, or the opposite, basic. Or, it could be in the middle — neutral, which is desirable. Acidic or basic water is measured on the pH scale. What Do You Call Safe? The USEPA has been in charge of the quality of U.S. drinking water since 1974, when the Safe Drinking Water Act (SDWA) passed. This law requires the USEPA to set standards for drinking water quality and monitor whether states, local municipalities, and water suppli- ers are in compliance. The Safe Drinking Water Act (SDWA) Under the SDWA, the USEPA sets limits on levels of certain contaminants in drinking water. It also sets standards for testing sched- ules and test methods, and determines which water treatment processes are acceptable. The SDWA, however, doesn't regulate private wells that serve fewer than 25 individuals. Regulating the byproducts of disinfection In 1998, the USEPA began requiring public water systems to use treatments that reduce the formation of disinfection byproducts. Specifically, the rule regulates hazardous chemicals such as TTHM, HAA5, bromate, and chlorite.
