GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 99.5 ft. Upper casing diameter 6 in; top of first opening 17 ft, bottom of last opening 99.5 ft. Drilled observation well, cased to 17 ft, open hole.
DATUM - Land-surface datum is 531.5 ft above North American Vertical Datum of 1988. Measuring point: top of casing, 2.0 ft above land-surface datum, Jun. 12, 1967 to present. Elevation of land surface is from Lidar.
PERIOD OF RECORD - January 1968 to current year.
GAGE - Data collection platform with 15-minute recording interval since April 2023; prior, 60-minute recording interval. Satellite telemetry at station.
COOPERATION - Site maintained in cooperation with the Pennsylvania Department of Environmental Protection and the U.S. Geological Survey.
REMARKS - Well shows significant response to earth tides. Water-quality records for 1973-75 are available in files of the USGS Pennsylvania Water Science Center. Daily maximum water levels are available for this well for the period of record. For some years, daily minimum and daily mean water levels may also be available from the USGS Pennsylvania Water Science Center Office.
EXTREMES FOR PERIOD OF RECORD - Prior to October 2000, the extremes shown were based on extremes of the daily maximum depth below land-surface datum. Since that date, the extremes are based on the instantaneous depth below land-surface datum. Highest water level, 8.71 ft below land-surface datum, Apr 16, 2011; lowest, 14.02 ft below land-surface datum, Jul 16-18, 1988.
