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. Studies beginning in the 1990s show that shallow groundwater contains nitrate above levels that are a concern. On May 10, 2004, following a public comment period on the final Southern Willamette Valley groundwater report and proposal for declaring a GWMA, DEQ declared the Southern Willamette Valley Groundwater Management Area for portions of the Southern Willamette Valley.
