Federal Judge Thomas O. Rice has ordered three dairies in the Lower Yakima Valley to conduct well testing and provide alternative drinking water solutions for residents potentially affected by nitrate contamination near Granger, Washington. The ruling came after a request from the U.S. Department of Justice, representing the Environmental Protection Agency (EPA), which believes that these dairies have contributed to nitrate pollution in the area’s groundwater.
The EPA has expressed concern over health risks associated with nitrate-polluted drinking water, highlighting dangers such as methemoglobinemia, or "blue baby syndrome," among other health effects. Pregnant individuals and those with certain health conditions are particularly at risk.
In June 2024, the Department of Justice filed a lawsuit against the dairies for allegedly failing to control nitrate contamination adequately. The court's decision requires these dairies to test wells up to 3.5 miles downgradient and offer reverse-osmosis systems or bottled water if nitrate levels exceed 10 milligrams per liter. Additionally, they must monitor groundwater and inspect a lined lagoon for leaks.
This order is part of ongoing legal proceedings aimed at addressing groundwater contamination and ensuring compliance with a 2013 agreement between the dairies and EPA. "Everyone deserves access to clean, safe drinking water," stated U.S. Attorney Vanessa Waldref, emphasizing her office's commitment to safeguarding public health in Washington.
Dan Opalski from EPA’s Region 10 office reiterated the agency's dedication to collaborating with various stakeholders to tackle public health challenges related to nitrate contamination in the region.
While this ruling addresses some immediate concerns, further efforts are necessary across the Lower Yakima Valley to mitigate widespread nitrate contamination affecting thousands reliant on underground water sources.
For residents outside of this ruling's scope, free well testing and alternative water solutions are available through local initiatives or by contacting designated hotlines.
