Summary

The potentiometric surface is important in monitoring effects of groundwater withdrawals, determining recharge areas, monitoring the possible travel of contaminates, placement of consumptive use wells, and is an important variable in a variety of hydrogeologic models and modeling goals.

Description

NOTE JANUARY 2014: UFA potentiometric surfaces for the following periods, were generated by SJRWMD staff for the SJRWMD, using Geovariance's Isatis geostatistical package: September 2009 & 2010, May & September 2011 & 2012. USGS decadinal May-June 2010 UFA potentiometric surface is also published (by USGS). See Technical Fact Sheet: http://www.sjrwmd.com/technicalreports/pdfs/FS > SJ2014-FS2.pdf.

An imaginary surface representing the static head of ground water and defined by the level to which water will rise in a well. The slope of the potentiometric surface defines the hydraulic gradient and the horizontal direction of groundwater flow. Potentiometric surface contours are generalized on a regional scale to portray water levels in a dynamic hydrologic system taking due account of the variations in hydrogeologic conditions such as well-depth differences, non-simultaneous measurements of water levels, variable effects of pumping, and changing climatic influence. The potentiometric contours, thus, may not conform exactly with individual measurements of water level.

Credits

SJRWMD. Additional Upper Floridan Aquifer water level well data acquired from the USGS, SWFWMD, SRWMD & SFWMD used as input to generate surface.

Use limitations

The potentiometric surface contours attempt to characterize a dynamic system on a regional scale. Site specific well head measurements may not conform with the contours. The St. Johns River Water Management District prepares and uses information for its own purposes and this information may not be suitable for other purposes. This information is provided ''as is''. Further documentation of this data can be obtained by contacting: St. Johns River Water Management District.
