AQUIFER.-- Biscayne limestone aquifer of Pleistocene Age, Geologic Unit 112 BSCNN.

WELL CHARACTERISTICS.-- Depth 140 ft. Upper casing diameter 2 in.; top of first opening 130 ft, bottom of last opening 140 ft.

DATUM.-- Top of casing, 18.79 ft above National Geodetic Vertical Datum of 1929, Nov. 1, 1995, to present

PERIOD OF RECORD.-- October 1988 to May 1990 (semiannual), September 1990 to October 1991 (intermittent), November 1991 to October 1995 (monthly), November 1995 to current year.

REMARKS.-- Well was designated PB 1105 until September 1992 and published under the current station number. Well was also used for salinity monitoring until October 1993. Published figures of water levels as elevation, in ft NGVD, are in error for November 1995 to September 1999. Corrected figures are available in the files of the U.S. Geological Survey. See DATUM.

EXTREMES FOR PERIOD OF RECORD.-- Highest daily maximum water level, 11.27 ft NGVD, July 13, 2002; lowest, 3.00 ft NGVD, June 17, 2004.

Current 30-day hydrograph at G -2852 (261938080101001)

Graph: Continuously recorded water levels for the past 30 days are compared to daily (maximum) water levels from last year, the minimum and maximum daily levels for the corresponding weeks of the year for the site period of record, and daily levels for the 2001 drought year.. Data used to produce this graph is available via the [data used] link on the page.

Long-term trend information

The change in daily water-level elevations correlates with time to a 95-percent degree of confidence for the past 25 years of record. A linear regression has been performed against the daily maximum water-level elevations for the past 25 years to quantify a long-term trend in the data. The estimated long-term trend in water level is 0.035 ft/year. (Description of statistical methods)
