The article expalins how a single-row grout curtain can complement a groundwater recovery-well system at a waste site. A continously pumping recoverey well can extract contaminated ground water, thereby producing large volumes of water to be treated. At an industrial landfill in New York, a 3-sided single-line grout curtain has increased the effectiveness of such a system, reducing the inflow groundwater from outside the site. The configuration of the curtain is described. Prior to design, the groundwater flow and remedial conditions were simulated using the USGS finite-difference modular model. The construction of the grout curtain is described. Water-test results showed that the grouting caused a sequential and substantial reduction in permeability. Prelimianry results of the geohydrologic monitioring of the grouting operations indicate that the grout curtain is functioning as designed, and that the effifiency of the groundwater recovery operations has improved.
