Navajo Nation Safe Drinking Water Act (NNSDWA)
The Navajo Nation Safe Drinking Water Act (NNSDWA), was initially adopted by
the Navajo nation Council in 1995. The NNSDWA has been revisited to include
the Underground Injection Control's provisions for protecting underground
sources of drinking water from activities conducted by the oil and gas industries.
In 2001, the NNSDWA was revised again to incorporate the revised public water
systems definition, provisions for the operator certification requirements, the
consumer confidence report requirements, amendments
to the variances and exemptions of the NNSDWA and
amendments to the judical sections.
Navajo Nation Primary Drinking Water Regulations (NNPDWR)
The Navajo Nation Primary Drinking Water Regulations (NNPDWR) was formally adopted by the Resources Committee of the Navajo
Nation Council, Navajo EPA's legislative oversight.
