Acid precipitation affects water supplies which in turn affects their users. Taylor and Symons (1984) report the results of the first study concerning the impact of acid precipitation on drinking water; the results report health effects in humans as measured by U.S. EPA maximum contaminant levels. The study sampled surface water and groundwater supplies in the New England states, but it also included other sites in the northeast and the Appalachians. No adverse effects on human health were demonstrated, although the highly corrosive nature of New England water may be at least partly attributable to acidic deposition in poorly buffered watersheds and aquifers.
