Economic risks – The economic risks posed by potential contamination of groundwater wells and the San Juan River are enormous. The river is a primary water source for Navajo and Jicarilla Apache people – well over 50 percent of the San Juan River watershed are Native American lands. The impacts of contamination will be much more widespread, with nearly every major population in New Mexico impacted by the river, whose waters are diverted to feed the Rio Grande reaching all the way to Albuquerque.
