‘The Evergreen’: Eastern Oregon’s polluted drinking water

A water pollution crisis has been unfolding in Eastern Oregon for decades. Contamination of the Lower Umatilla Basin’s groundwater with excess nitrates — a naturally occurring chemical also found in fertilizer — has meant residents of Morrow and Umatilla Counties who get their water from private wells are struggling to access clean drinking water. Though the issue has been a known problem for over thirty years, nitrate pollution there is only getting worse, and some residents are still just learning about the risks to their health.
