Lamb Weston seeks to widen Umatilla nitrate pollution lawsuit

Lamb Weston, a potato processor, seeks to expand a lawsuit over groundwater pollution in Oregon's Umatilla basin by adding J.R. Simplot Co. and Shearer’s Foods as defendants. Lamb Weston denies liability but argues the other companies should share responsibility. The original plaintiffs oppose this, citing potential delays and complications. Oregon's DEQ has linked the defendants' wastewater practices to groundwater harm.
