Abstract

Test borings at 28 sites and seismic-refraction profiles at 16 sites provide data on the saturated thickness and grain-size characteristics of stratified-drift deposits in five areas of Connecticut. These data, together with information on the areal extent of the deposits and their proximity to sources of induced recharge, can be used to estimate the water-yielding potential of the stratified-drift deposits. Individual wells could potentially yield moderate to possibly very large quantities of water (50 to 2000 gallons per minute) at some locations in all five areas where saturated, dominantly coarse-grained stratified drift is 40 feet thick or greater and hydraulically connected to nearby surface-water bodies. Coarse-grained stratified drift is most extensive in the Glastonbury, Haddam, and Simsbury, Connecticut areas. Saturated thickness exceeds 150 feet in parts of the Glastonbury and Haddam areas, but is less than 100 feet in most places. The best sites for developing large quantities of water are in the Glastonbury and Haddam areas where thick, saturated, coarse-grained stratified drift is hydraulically connected to the Connecticut River. Water in the stratified drift is generally of good chemical quality except for excessive iron (0.64 to 20 mg/L) and manganese (0.1 to 10 mg/L) in some samples. (USGS)
