Description High enterococcus bacteria counts detected during a reconnaissance survey in 1991 indicated a possible public health risk in the lower Columbia River. The purpose of this project was to determine if a chronic public health risk exists during high contact recreation periods due to bacteria contamination. Ecology sampled 12 stations between the mouth of the Columbia River and river mile 170 (Hood River) weekly from September 1 to October 12, 1992. Fecal coliform and enterococcus bacteria were monitored, as well as oxygen, temperature, pH, and conductivity.
