Data on observation wells, ground-water levels, and ground-water quality for the stratified-drift aquifer in the northwestern basin of Country Pond, Kingston, New Hampshire

Observation-well, ground-water-level, and ground- water-quality data were collected for a study of ground-water contamination in stratified drift at Country Pond in Kingston, New Hampshire. The report includes drilling records for 30 wells installed at various depths in stratified drift beneath Country Pond. Ground-water levels are recorded for nine wells drilled under the direction of the U.S. Geological Survey in May 1991. Water-quality analyses are presented for 56 ground-water samples collected from 30 wells drilled during the investigation. Samples were analyzed in the laboratory for 40 volatile organic compounds. Ground-water contamination from volatile organic compounds was found in 23 of the 56 samples collected.
