The intention of this investigation is to evaluate the pollution of Rocky Fork Creek in Richland County, Ohio in order to determine its affect upon the aquatic environment. The violation of aesthetic values as well as some aspects of economic damage will also be considered. To achieve this means laboratory analyses and historical research were essential. Water and sediment samples were taken from several collection sites located near to and within Mansfield, Ohio. Additionally, a few preliminary tests were conducted in the field and observations noted at each of the sampling sites. The samples were then taken to the laboratory to be analyzed for concentrations of ten different ions to see if the drinking water standards of the United States Public Health Service were met. In regard to these tests and observations, the author found, during the course of the investigation, that heavy metals, aside from a few isolated sources, are not presently much of a problem. The pH level is also back to normal and no longer frequently fluctuates from one extreme to the other as it surely must have done in the past. Sources of sewage are gradually diminishing, but total solids and grease and oils are still posing somewhat of a problem in the stream. Thermal pollution, though minor, will continue to persist.
