Investigations of Sources of Contaminants of Concern in the San Juan River

Metals attached to suspended sediments or dissolved in river water pose a potential health risk to communities that depend on that water for agricultural and domestic uses. Exceedances of Navajo Nation surface water quality standards for metals (especially lead and arsenic) indicate that communities on the Navajo Nation along the San Juan River are exposed to this potential risk.
