An assessment of groundwater quality in the vicinity of eight landfill sites accepting various quantities of municipal sewage sludge was performed. An appraisal was also made of the operations and economics at each location. The study consisted of two phases. The first included a preliminary assessment of the environmental impacts of sewage sludge burial practices at the eight sites. In the second phase, additional data on leachate and groundwater quality trends over a 12-month period were obtained. Two sites were selected for more intensive groundwater monitoring to determine the areal extent and degree of groundwater quality impact. The results showed that landfilling of sewage sludge released significant contaminants in the form of leachate. Among the contaminants analyzed, iron, lead, and TOC in excess of EPA Drinking Water Standards were found most frequently. Contaminants traveled at least several hundred meters beyond the immediate disposal area, despite the existence of soil strata with low permeability. The monitoring data demonstrated the extreme difficulty in selecting monitoring well locations and sampling depths and establishing a sampling frequency necessary to obtain valid information for measuring landfill impacts on groundwater.
