This report contains geologic, ground-water, and quality-of-water data collected and compiled for a water resources investigation of the upper Connecticut River basin, Connecticut by the U.S. Geological Survey in financial cooperation with the Connecticut Department of Environmental Protection. These data, together with surface-water data, were collected at sites shown on plate A and are, with exceptions discussed below, presented herein. The interpretation of these data will be published separately in Connecticut Water Resources Bulletin No. 24.
As defined for this investigation, the upper Connecticut River basin is a
508-square-mile area in north-central Connecticut (see front cover and plate A)
drained by the Connecticut River and its tributaries including the Farmington
River downstream from the community of Tariffville. The basin includes all or
parts of the following 30 towns: Avon, Bloomfield, Bolton, Cromwell, East Granby,
East Hampton, East Hartford, East Windsor, Ellington, Enfield, Farmington,
Glastonbury, Hartford, Manchester, New Brltain, Newington, Plainville, Portland,
Rocky Hill, Simsbury, Somers, South Windsor, Stafford, Suffield, Tolland, Vernon,
West Hartford, Wethersfield, Windsor, and Windsor Locks.
The data compiled for this investigation consist of those collected specifically
for the study during the period July 1967 - December 1969 and those
collected during previous investigations. Many records of wells and test holes in
thus report were published in Connecticut Water Resources Bulletin No. 4. This
report is out of print, therefore these previously published records, together
with newer ones, are published in this report to provide a readily available
source of ground-water information. Previously published well numbers have
been retained and are those published in this report. However, test holes
previously published as wells have been assigned test-hole numbers; the former
well number Is noted in table 3.
