Ground‐Water Transport from Wastewater Infiltration

Abstract
Ground water contaminant transport was investigated from a municipal wastewater infiltration system. Ground water quality samples were collected at the Fort Devens, Massachusetts facility from surrounding wells and were analyzed for conductivity and trace level organics contamination. Groundwater flow and chloride contaminant transport were predicted using a two‐dimensional numerical simulation model. Dispersion estimates were made using organics data collected at adjacent wells and adjusted for adsorption in the porous media. Results for field dispersion compared favorably with other values reported in the literature. Methods used in this field project along with modeling techniques should be applicable to other ground‐water waste contaminant sites.
