SHC Project 3.1.5 Decision Support for Organic Contaminant Transport SHC project 3.1.5 and related work has as its culmination a modeling system that is intended to be used to assess contaminated sites’ impacts to public and private drinking water supplies. Given a landscape that contains solvent sites, landfills, leaking underground storage tanks, and dry cleaners with releases, the modeling system is intended to be part of a decision support system for communities to assess costs and alternative decisions on sources of water supply. Work on contaminant remediation (SHC 3.1.5.1) feeds the modeling system as a component of the ground water environment and an element of cost to balance against costs of alternate water supply. Although the main focus is on ground water, few communities rely solely on ground water other water supply elements (rivers, lakes, reservoirs, pipelines) are considered as elements of the modeling system. Population increase, natural cycles of wet and dry years and climate change impose constraints on sources of supply. Coupled with these considerations are community decisions on building water supply infrastructure, which bring more economic and social considerations to the analysis.
