Northern Malheur County Groundwater Management Area

The Northern Malheur County Groundwater Management Area was declared in 1989 after widespread groundwater nitrate contamination was identified that had resulted primarily from nonpoint source activities. Oregon DEQ and a citizen’s advisory committee created an Action Plan for restoring the groundwater nitrate concentrations to acceptable levels. The Action Plan identifies specific "measures" to gauge the success of groundwater restoration activities in the area.
