Act and Regulations
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 revised 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 system
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 judicial section.
