Last week, a $6.2 million settlement was made between Madison Ranches and residents living in Morrow and Umatilla Counties whose wells were polluted with nitrates. The Lower Umatilla Basin has been grappling with high levels of nitrates for decades, affecting drinking water in wells in various communities. Food processors and farms using fertilizers are regarded as the source of the problem.
