Use Of A Field Drain And An Artificial Wetland To Minimize Ground-Water Contamination From An Agricultural Site

摘要

The Conestoga River Basin wetland study was designed to evaluate the potential for collecting and treating nitrate-contaminated shallow ground water in agricultural areas underlain by carbonate bedrock. It was performed in cooperation with the Pennsylvania Department of Environmental Protection, Bureau of Watershed Conservation. The project's three major elements are: (1) the design and installation of a field-drain collection and wetland treatment system at a farm in Lancaster County, Pa.; (2) monitoring and assessment of the ability of the constructed wetland to remove nutrients from the field drain discharge; and (3) an evaluation of the effectiveness of the drain in capturing shallow ground water with an analytical or numerical cross-sectional model.
