A study of the hydrogeology of sludge application areas in the sandy agricultural land near Rockton, Illinois was conducted to evaluate possible contamination of the groundwater by sludge constituents. Over a 2-year period, a total of 16 monitoring wells was installed at four sites. Two sites were characterized by repeated applications of sludge and two were background sites. Two soil-water samplers were also installed at each sludge application area. The monitoring wells and soil-water samplers were used to determine groundwater flow and quality. Nitrate concentrations were higher at sludge application sites than at background sites and higher in downgradient wells than in upgradient wells. There was no apparent contamination from metals or organic chemicals.
