Systems that are listed in this Appendix are often out of compliance due to the Surface Water Treatment Rule. The rule went into effect in 1993, and is a product of the 1986 Safe Drinking Water Act Amendments. For many systems coming into compliance with the Surface Water Treatment Rule requires completion of a major long term project, such as construction of a water filtration plant. In the interim, systems must provide increased disinfection to assure the safety of their supply. These violations are usually dealt with quickly by disinfecting of the water system.
Disinfection kills microorganisms.
Public water systems with this type of violation need to be on a regular disinfection program. There are 17 public water systems that had maximum contaminant levels violations, excluding microbiological contamination. These violations are mainly chemical primarily small systems. The contamination is generally mitigated through treatment or by finding another water source.
