371208076341104 58F 53 SOW 171D
Northern Atlantic Coastal Plain aquifer system
Eocene Series
LOCATION - Lat 37°12'08", long 76°34'11" referenced to North American Datum of 1927, Newport News City, VA, Hydrologic Unit 02080206, 0.4 mi southeast of the intersection of State Highways 143 and 238 and 150 ft north of State Highway 143 in Newport News. Owner: Virginia Department of Environmental Quality.
GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 343 ft. Upper casing diameter 4 in; top of first opening 333 ft, bottom of last opening 343 ft. Drilled observation water well, screened 333 to 343 ft.
DATUM - Land-surface datum is 55 ft above National Geodetic Vertical Datum of 1929. Measuring point: TOP OF CASING, 2.90 ft above land-surface datum, Apr. 14, 1993 to present.
PERIOD OF RECORD - July 1984 to current year. Unpublished records available prior to October 1986 in files of the USGS.
GAGE - Electronic data logger and pressure transducer, 15-minute record interval. Oct. 1, 1999 to Mar. 23, 2007, occasional measurement with chalked tape by USGS and Virginia Department of Environmental Quality - Water Division personnel. Prior to Oct. 1, 1999, digital recorder, 60-minute record interval.
COOPERATION - Records provided by the Virginia Department of Environmental Quality - Water Division.
REMARKS - Well is located in Chickahominy-Piney Point aquifer of Eocene-Oligocene age. Water level affected by regional drawdown and occasional pumpage for water-quality sampling. Water from this well is known to contain concentrations of dissolved solids greater than 1,000 mg/L. Drop in water level in April-May 2009 and April 2013 result of well having been pumped for water quality sampling. Record for period Dec. 1, 2009 to Apr. 27, 2010 questionable due to instrumentation problems.
EXTREMES FOR PERIOD OF RECORD - Highest water level recorded, 55.18 ft below land-surface datum, Feb. 2, 1985; lowest recorded, 72.67 ft below land-surface datum, Sept. 16-19, 2016.
