Framework for Evaluating Water Quality of the New England Crystalline Rock Aquifers
Philip T. Harte, Gilpin R. Robinson Jr., Joseph D. Ayotte, Sarah M. Flanagan
2008, Open-File Report 2008-1282
Little information exists on regional ground-water-quality patterns for the New England crystalline rock aquifers (NECRA). A systematic approach to facilitate regional evaluation is needed for several reasons. First, the NECRA are vulnerable to anthropogenic and natural contaminants such as methyl tert-butyl ether (MTBE), arsenic, and radon gas. Second, the physical...
