ORA board member Mitch Wolgamott, former Department of Environmental Quality Acting Administrator Eastern Region.

In 1990, the Oregon DEQ declared the Lower Umatilla Basin (an area stretching from Morrow county to Umatilla county) a groundwater management area. In 1999, Threemile Canyon Farms moved into the area.

Samples taken from different test sites around the basin showed levels of nitrate-nitrogen exceeding the federal safe drinking water standard. In the early 2000s, Mitch directly oversaw the area of the Lower Umatilla Basin Groundwater Management Area working to reduce the nitrate levels in the area’s water.

High nitrate levels, above 10 parts per million (ppm), in drinking water can cause people to get sick, especially infants, the elderly and people with immune disorders. High nitrate levels reduce red blood cells’ ability to carry oxygen. This can cause methemoglobin in infants, the elderly and immune deficient individuals. Methemoglobin symptoms include headache, dyspnea, lightheadedness, weakness, confusion, palpitations and chest pain.

The levels of nitrate-nitrogen are particularly high in this area because of irrigation seepage into the groundwater. Grains, hay and grasses for livestock make up the majority of agriculture in the county.
