“…The Coastal Plain and Triassic and Jurassic Low land were selected as the most favorable areas to explore for supplemental public water supplies in Fairfax County, Virginia, based on preliminary re sults of the Fairfax County environmental geology study (Johnston and Froelich, 1977;Johnston and Larson, 1977). The Fairfax County Board of Super visors, acting on these preliminary results, recom mended-and the Fairfax County Water Authority agreed to fund-an exploratory drilling and aquifer test program.…”
