Service Description: Based on Oregon's Groundwater Protection Act of 1989, DEQ is required to declare a Groundwater Management Area (GWMA) if area-wide groundwater contamination caused primarily by nonpoint source pollution, exceeds certain trigger levels. Because elevated nitrate levels were detected in many wells within a 352,000 acre portion of Umatilla and Morrow counties, DEQ declared the Lower Umatilla Basin GWMA in 1990.
