What are the rules?A strict set of standards guides the drinking water industry. The underlying rule for germs is that there should be no fecal organisms in the water. Testing procedures and proper water treatment are carefully defined and enforced.
Drinking Water Act (SDWA) was enacted in 1974 by the US Congress; it was
revised and updated in 1986 and 1996. The US Environmental Protection
Agency (EPA) enforces SDWA by requiring each state to designate an agency
to oversee its water suppliers. States may make certain provisions of
their laws more strict than SDWA, but no one can change SDWA rules to
make them more lenient.
