GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 57 ft. Upper casing diameter 6 in; top of first opening 9 ft, bottom of last opening 57 ft. Open hole 12 to 57 ft.
DATUM - Land-surface datum is 10.82 ft above National Geodetic Vertical Datum of 1929. Measuring point: Top of shelf, 14.62 ft above National Geodetic Vertical Datum of 1929, Jan. 1, 1971 to Oct. 1, 1981; Top of recorder shelf, 11.85 ft above National Geodetic Vertical Datum of 1929, Oct. 1, 1981 to present. See REMARKS.
PERIOD OF RECORD - January 1971 to current year.
GAGE - Satellite data collection platform. Prior to January 2009, Electronic data logger.
REMARKS - The figures of water level as elevation, in feet NGVD, from October 1981 to September 1982 are in error. A correction of -2.77 ft has been applied to correct water-level data. Corrected records are in files of the U.S. Geological Survey. See DATUM. Records of water levels prior to October 1975 are available in files of the U.S. Geological Survey. The well was originally open to the aquifer from 12 to 57 ft. The open interval of the well has collapsed at a depth of 36 ft. Water-level data from this well are not considered to be affected by the collapsed interval.
EXTREMES FOR PERIOD OF RECORD - Highest water level, 8.57 ft NGVD, Sep. 10, 2017; lowest, 0.95 ft NGVD, May 14, 15, 1975.
