Abstract

A study of Fecal coliform distribution at the lower end of Catfish creek in Southern Dubuque County, Iowa was conducted from November 4 until December 30, 1970. The creek's mouth is approximately 1/4 mile below the outflow pipe of the Dubuque wastewater treatment plant on the Mississippi River. The plant presently has only primary treatment, but a new plant is scheduled to begin operation soon. This and subsequent studies will show the actual effect on the surrounding environment of introducing secondary treatment to a primary wastewater treatment plant. It was found that the contamination levels below the Dubuque wastewater treatment plant outflow pipe were high. In turn, backwaters of the Mississippi River carried this contamination about 1/4 mile upstream into Catfish creek. The Mississippi River water level had a direct effect on the extent of pollution of Catfish creek upstream from the Mississippi River.
