"Groundwater underneath a 40 acre ash disposal area, seven industrial waste water ponds and a 1,500 acre closed-loop reservoir at the Boardman Plant has been contaminated in excess of Oregon groundwater standards, EPA Maximum Contaminant Levels (MCLs) and Secondary MCLS since 1981," the report says. "A farming operation has been using large volumes of water from the closed-loop lake since 2001 despite the plant's disposal of bottom ash drain water and other liquid industrial wastes into this reservoir."
