The sources are considered most vulnerable to the following: lagoons/liquid wastes, pesticide, fertilizer application and storage, agricultural drainage, animal feeding and grazing operations, and high density and low density septic and sewer collection systems. At the time, there were no associated contaminants detected in the water supply, however the source was still considered vulnerable to automobile/gas stations, farm machine repair, fleet trucks and bus terminals and machine shops and wastewater treatment plants.
