Well-point containment of impoundment leakage.
Tuscaloosa, AL: U.S. Department of the Interior, Bureau of Mines, RI 9546, 1995 Jan; :1-16
Research was conducted to evaluate the effectiveness of a well- point dewatering system in conjunction with a French drain to intercept waste impoundment leakage while reducing the volume of waste water requiring treatment. A well-point dewatering system composed of 585 production wells was installed around the perimeter of a leaking impoundment that previously used only a French-drain system for leakage control. The placement of the well-point system was designed to intercept and remove the leakage from the groundwater before the contaminant reached the French drain. Groundwater monitoring at this site revealed that after a period of approximately 40 days the well-point dewatering system had stabilized and effectively prevented the further spread of contamination to the French drain.
