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, adding J.R. Simplot Co. and Shearer’s Foods as defendants. The company denies liability but argues they should share blame if found responsible. The original plaintiffs oppose the move, citing potential delays and complications. The case is set for trial in June 2027.
