Ground-water availability and water quality in Farmington, Connecticut
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)
Geologic data obtained from core samples drilled in the vicinity of Chaplin, Windham County, Connecticut
During the summer of 1966, a rotary—drill rig and crew were made available for 2 weeks to the U.S. Geological Survey for use specifically in eastern Connecticut. I was able to take advantage of this opportunity and proposed to investigate two geologic problems that had arisen in the vicinity of Chaplin, Conn., as a result of mapping by H. R. Dixon in the Hampton quadrangle (Dixon and Pessl, 1966) and by G. L. Snyder in his reconnaissance of the W-adjacent Spring Rill quadrangle (Snyder, written commun., 19661. (See figure 1 for the conflicting interpretation along the border of the quadrangle.)
Water resources data for Connecticut, water year 1979
Water resources data for the 1979 water year for Connecticut consist of records of stage, discharge, and water quality of streams; contents and water quality of lakes and reservoirs; and water levels and water quality of ground-water wells. This report contains records of water discharge at 56' gaging stations; stage only at 1 gaging station; tidal volume at 1 gaging station; stage only records at 2 tidal-gaging stations; contents at 36 lakes and reservoirs; water quality at 50 gaging stations, 5 lakes and reservoirs, 2 harbors; 34 wells, and 1 spring; and water levels at 66 observation wells. Also included are data for 41 creststage partial-record stations. Locations of these sites are shown on figures 2, 3, and 4. Additional water data were collected at various sites, not involved in the systematic data-collection program, and are published as miscellaneous measurements and analysis. A few pertinent stations (not included above) in bordering States are also enclosed in this report. These data represent that part of the National Water Data System operated by the U.S. Geological Survey and cooperating State and Federal agencies in Connecticut.
Hydrogeologic data for the lower Connecticut River basin, Connecticut
This report contains geologic, ground-water, and miscellaneous data on the quality of surface water collected for a water-resources inventory of the lower Connecticut River basin, Connecticut. The study was made by the U.S. Geological Survey in fiscal cooperation with the Connecticut Department of Environmental Protection. A companion report (Connecticut Water Resources Bulletin No. 31, in preparation) interprets the factual information presented here or otherwise collected for the study.

Water resources data for Connecticut, water year 1977
Water resources data for the 1977 water year for Connecticut consist of records of stage, discharge, and water quality of streams; contents and water quality of lakes and reservoirs; and water levels and water quality of ground water. This report contains discharge records for 50 gaging stations; tidal volume for 1 gaging station; stage only records for 3 tidal-gaging stations; contents for 36 lakes and reservoirs; water quality for 56 gaging stations, 3 lakes, 28 wells, 4 springs, 4 seepage sites, and 1 chemical precipitation station; and water levels for 21 observation wells. Also included are 44 crest-stage partial-record stations and 38 low-flow partial-record stations. Additional water data were collected at various sites, not involved in the systematic data collection program, and are published as miscellaneous measurements. Locations of hydrologic stations are shown on figures 2, 3, and 4. A few pertinent stations (not included above) in bordering States are also enclosed in this report. These data represent that part of the National Water Data System operated by the U.S. Geological Survey and cooperating State and Federal agencies in Connecticut.
