262711081413701 L 2550.
Surficial aquifer system
Sandstone Aquifer
LOCATION - Lat 26°27'12", long 81°41'37" referenced to North American Datum of 1927, in NE 1/4 SE 1/4 SE 1/4 sec.22, T.46 S., R.26 E., Lee County, FL, Hydrologic Unit 03090204, 0.75 mi east of Alico Road, 0.05 mi north of Corkscrew Road, 1.8 mi east of U.S. Interstate 75, and 8.2 mi east of Estero Post Office.
REVISIONS HISTORY - Groundwater levels above NGVD29 for the period Dec. 19, 2017 to Feb. 21, 2018 were revised on June 7, 2018. The incorrect measuring point elevation was used. The correct measuring point is 0.04 ft higher. Water-level elevations for the period were corrected by adding the difference between the incorrect measuring point and the correct measuring point (+0.04).
GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 134 ft. Upper casing diameter 6 in; top of first opening 67 ft, bottom of last opening 134 ft. Artesian well, open hole 67 to 134 ft.
DATUM - Land-surface datum is 18.57 ft above National Geodetic Vertical Datum of 1929. Measuring point: Undefined. See REMARKS.
PERIOD OF RECORD - March 1992 to current year.
GAGE - In-Situ Level Troll 500 pressure transducer.
REMARKS - The figures of water as elevation, in ft NGVD, from March 1992 to October 2002, are in error. A correction of +0.04 ft is required to correct water-level data. See DATUM.
EXTREMES FOR PERIOD OF RECORD - Highest water level, 20.35 ft NGVD, Sept. 13, 2017 (present datum); lowest, 6.70 ft NGVD, June 6, 7, 8, 1999 (present datum).
