Norwich, a small city in Eastern Connecticut located in New London County, is at the source of the Thames River that flows into Long Island Sound passing the U.S. Submarine base in Groton and the Coast Guard Academy in New London along its way. The area contains several other small cities, most of which supply some of their residents with municipal water. Small towns also spread over the 600 sq. miles of county land along with some farms and many residential areas. Gradually over the years a considerable number of well water tests began to show pH's below the desirable range of 6.5 to 9.0. A summary of these pH tests and the increasing acidity trends are shown in Figure 1. for two types of wells, dug and drilled.
