Abstract Details

2007, Master of Science (MS), Bowling Green State University, Geology.
Williams County is a mostly agricultural county located in northwest Ohio. It currently has three Confined Animal Feeding Operations (CAFOs), all dairy, with the possibility of the construction of a multi-million chicken egg CAFO in the near future. A Geographic Information System (GIS) was utilized to modify the Ohio Department of Natural Resources (ODNR) DRASTIC map for the county to fully assess the county-wide pollution potential of CAFOs. DRASTIC is a model for displaying the relative spatial comparison of groundwater pollution potential. Three of DRASTIC’s parameters (Depth to Water, Soil Media, and Topography) were modified and another parameter was added (Land use/land cover) to the model to determine the potential impact on groundwater from CAFO manure lagoon settings and manure application as fertilizer. Results indicate that 87 percent of Williams County has elevated CAFO groundwater pollution potential. The CAFO DRASTIC map shows that only 13 percent of the county, primarily the southeast corner, has much lower CAFO groundwater pollution potential. Evidence from this study suggest that future CAFO development within the county should focus on the southeastern portion of the county, where the groundwater table is deeper and the aquifer is composed of shale substrate with low hydraulic conductivity. The CAFO DRASTIC results are intended to be used as a screening tool, and are not to replace site-specific hydrogeologic investigations.
