ABSTRACT
In a detection or source groundwater monitoring program, wells passively intercept enclaves (plumes) of contamination moving away from waste storage facilities such as landfills (Todd, 1980). Networks of source-monitoring wells should provide an opportunity for detecting contaminants released from any location within a potential contaminant source (EPA, 1994). The monitoring network should take into account the direction(s) of groundwater flow, rock and soil characteristics, and locations of neighboring properties or water supply wells (Loaiciga et al., 1992).
