Abstract
The strataified-drift aquifer in Farmington, Conn., is capable of yielding large amounts of water to individual wells. About 14 square miles of Farmington is underlain by stratified-drift deposits which, in places, are more than 450 feet thick. The most productive deposits are found in the Farmington River valley, from Unionville to River Glen, and along Scott Swamp Brook. In these areas, saturated, coarse-grained, stratified-drift deosits exceed 80 feet in thickness and estimated yields to individual wells ranged from 250 to 1,000 gallons per minute. Results of mathematical model analysis of three of the most favorable ground-water areas indicate that long-term yields range from 1.2 to 2.5 million gallons per day. Water in the Framington and Pequabuck Rivers meets the Connecticut Drinking Water Standards, assuming complete conventional treatment, for coliform orgaisms, color, trubidity, chloride, copper, and nitrate. Coliform bacteria concentrations in the Pequabuck river (12-month geometric mean of about 6,800 colonies per 100 milliliters of water) indicate a potential problem. Water in the stratified-drift aquifer is of good quality with the exception of manganese; 10 of 11 wells sampled had maganese concentrations above 0.05 milligram per liter. (USGS)
