Summary/Goals: Develop a tool to aid small water providers with decisions on feasible methods of reducing arsenic concentrations in water supplies. While the main contribution of our work is to expose providers information on potential non-treatment options such as well-lining and mixing of sources, our decision support toll includes conventional treatment options as well.
Activities and outcomes during past year:
Jacob Davis, the Master's student working on the project, successfully defended his M.S. Thesis in July 2005. His thesis included a demonstration of the decision support tool which integrates knowledge of concentrations of arsenic in geologic formations, information on the location of small water providers, and costs of non-treatment options that may be feasible for each water provider.
Plans for the upcoming year:
We will refine the decision tool to include more detail information on the costs of non-treatment options and finer geographic scale. Hogan and Stewart will also be discussing the model results and potential extensions in the workshop "Innovations in Arsenic Management for Water Providers" in February 2006.
