The following report is a summary of all data collection from 1985 through 1991 on a study of barnyard impacts on groundwater quality and the effects of installing state of the art manure handling systems in an attempt to improve water quality. This project was undertaken as a cooperative project between the University of Wisconsin – Stevens Point, Wisconsin Department of Natural Resources, Portage County Land Conservation Department, Wisconsin Department of Agriculture, Trade and Consumer Protection, United States Soil Conservation Service and the cooperating farmers.
Details results of the first two years of the project are available from the Master of Science thesis of Brian Bowen and Michael Travis. Complete chemical analysis is presented in the appendix. Four of the original five study sites are discussed in this report. The fifth site was found to be nonrepresentative of soil conditions to be evaluated by this project, and was not continued after the first two years.
Weather conditions throughout the project were extremely variable, and included two very dry years, 1988 and 1989. This is shown in figure 1, along with water table elevation data, which was effected by the varying rainfall amounts.
Figure 2 shows the location of the study sites in Portage County, located in the central part of Wisconsin.
