Lower West Coast Hydrogeologic Unit Golden Spike Wells 2015

Sites where the hydrogeologic aquifer picks had the highest confidence were designated “golden spike” wells and were used as benchmarks during data evaluation. The basis for the golden spike designation was a well that had a high quality data set, conformed to project unit criteria and were given a ranking of 1. Candidate wells for golden spike classification were preferred if they had been recommended as representative by a local utility, had data available for reassessment, and/or had multiparty agreement. Golden spike data were also obtained from SWFWMD to correlate wells in the northern portion of the project area along the boundary between SFWMD and SWFWMD. This data set was developed in 2014 and 2015 in support of the Hydrogeologic Unit Mapping Update for the Lower West Coast Water Supply Planning Area (see Technical Publication WS-35)The objectives of this study were to create regional hydrogeologic maps including contour maps showing unit surfaces and thicknesses, and cross-sections representative of both the surficial aquifer system (SAS) and intermediate aquifer system (IAS). The maps, source data, and metadata used to generate these products will be archived in a manner suitable for model implementation and regulatory use in a publically accessible format. The results will be incorporated into the forthcoming Lower West Coast Surficial Aquifer System and Intermediate Aquifer System Model (LWCSIM), which will evaluate the potential impact of existing and projected groundwater withdrawals in all SAS and IAS aquifers within the region over the next several decades.For full documentation, please see Technical Publication WS-35, "Hydrogeologic Unit Mapping Update for the Lower West Coast Water Supply Planning Area," dated August 2015 by Elizabeth Geddes, Emily Richardson P.G., and Anne Dodd P.G. , Water Supply Bureau, Water Resources Division, South Florida Water Management District, West Palm Beach, Florida. https://www.sfwmd.gov/sites/default/files/documents/ws-35_lwc_hydrogeologic_mapping_083115.pdf
