The Waverly Ground Water Contamination site is in Waverly, Lancaster County, Nebraska. At this municipally owned site, the ground water aquifer provides 100 percent of the drinking water for the community of approximately 2,000 people through the municipal water system. Between 1952 and 1974, a Federal grain facility, located on a portion of the site, was the source of ground water contamination. From 1955 to 1965, the fumigant 80/20, composed of 80 percent carbon tetrachloride and 20 percent carbon disulfide, was used onsite on stored grain. The contaminants of concern affecting the soil and ground water are VOCs including carbon tetrachloride and chloroform. The selected remedial action for the site includes continued operation and maintenance of the ground water air stripping system and the soil vapor extraction system; ground water monitoring to delineate the magnitude and extent of contamination; evaluation of the construction of PWS 3 to explain the contamination in the well; sampling existing and new monitoring wells; development of a ground water flow and transport model to determine the correct pumping rate for the existing ground water extraction well, and investigation of the potential uses for the treated water discharged offsite.
