Project Brief
The U.S. Environmental Protection Agency helps tribal governments and utilities implement the Safe Drinking Water Act on tribal lands. When EPA’s Region 9 needed further capabilities for its SDWA support at the Navajo Nation in New Mexico, it turned to ERG. ERG assisted with inspection of the Nation’s public water system; collected samples from source water and taps; prepared and delivered samples to SDWA-certified laboratories for analysis for total coliform, E. coli, nitrates/nitrites, cyanide, mercury, total metals, fluoride, and sodium; and developed a technical report summarizing the results. This work confirmed that the Navajo Nation’s drinking water met SDWA requirements.
