Ecoregion frameworks are available tools for inventorying and assessing environmental resources, for setting resource management goals, and for developing biological criteria and water quality standards. In a collaborative project with the Massachusetts Department of Environmental Protection, Division of Water Pollution Control (DWPC), we have refined the boundaries of the U.S. Environmental Protection Agency's two major ecological regions in the Commonwealth of Massachusetts, defined 13 subregions, and mapped boundary transition widths. Lists of candidate stream reference sites have been developed for each subregion, and the sites are being examined and evaluated by DWPC staff to determine their suitability for sampling. Phosphorus and alkalinity data for lakes and streams have been collected, evaluated, mapped and analyzed to determine spatial distributions and regional patterns. The resulting regional frameworks and maps of surface water chemistry lead to a better understanding of the spatial variations in water resource conditions in Massachusetts.
