The Southern Willamette Valley is one of Oregon’s fastest growing regions and depends heavily on groundwater for both private and public drinking water, irrigation water, and other uses. The Groundwater Management Area is the result of many years of studies and analyses of the shallow groundwater in the lowlands of the Southern Willamette Valley. 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 Groundwater Management Area, DEQ director Stephanie Hallock signed the official Declaration, creating the Southern Willamette Valley Groundwater Management Area. By declaring a Groundwater Management Area for portions of the Southern Willamette Valley, DEQ, Department of Agriculture, Water Resource Department, Department of Human Services and other state agencies are required to focus efforts on the development of an Action Plan to restore the groundwater quality.
