Public Water Systems Supervision Program
The Public Water Systems Supervision Program is under the Surface and Groundwater Protection Department of the Navajo
Nation Environmental Protection Agency  The NNEPA is an  independent entity within the Executive Branch of the Navajo Nation
government.  The Surface and Groundwater Protection Department is responsible for protecting the waters of the Navajo Nation.

PWSSP enforces the Navajo Nation Safe Drinking Water Act (NNSDWA) to ensure that public water systems provide safe drinking
water.  PWSSP requires owners/operators of public water systems to maintain records, monitor and sample for contaminants, report
the results to NNEPA, and notify the public if there is an exceedance.  PWSSP provides technical assistance to owners/operators
with the goal of achieving compliance of NNSDWA.
Navajo Nation Safe Drinking Water Act
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.
Water is a Precious Resource
Most people take water for granted. Many people assume that the water will always come out of their kitchen tap and that it will
always be wholesome. It is the job of the water system operator to get the water from the source to the consumer’s tap. This may
involve pumping water out of the ground or diverting a stream, then removing harmful contaminants, and pumping the water
through miles and miles of pipe.  Water in the ground may be free, but getting the water from the source to the people’s homes and
making sure that it is safe costs money.  An important part of the operator’s job is to help people understand why piped water to
their homes is not free.
