Abstract

On August 1, 1978, a water quality survey of Muchakinock Creek was performed by University Hygienic Laboratory personnel. The purpose of the study was to obtain background data on a watershed that has been extensively mined for coal and to assess the impact of the Oskaloosa Waste Water Treatment Plant discharge on the receiving stream. Results indicate the Oskaloosa discharge had minimal affect on Muchakinock Creek at the existing stream flows. General stream water quality was typified by moderately high specific conductance and total residue, low organic nitrogen and carbon levels, low alkalinity and pH. The high soil iron and sulfur content affects ground water quality which may affect stream water quality during periods of ground water recharge to the stream.
