The product of this research has extensive application to the drinking water and regulatory communities for assessing source waters, enriching the ability to assemble and evaluate all existing and readily available water quality-related data and information. Specifically, this project documented chemical data stored in a variety of databases and provided a mechanism to access it and the associated metadata. The online tool, Source Water Quality Database, provides information on water quality data related to chemical occurrence stored in national, regional, and state data sets.
