Submerged Springs Site Documentation: August and September 2007

摘要

The St. Johns River Water Management District (SJRWMD) contracted with Karst Environmental Services, Inc. (KES) to assist in ground-truth investigations and the site documentation of various submerged springs and other undocumented sites that were identified as possible groundwater discharge locations by aerial thermography. KES also provided assistance to the SJRWMD and USGS with water sample collection for water quality analysis, and conducted discharge measurements as part of the Silver Springs Characterization Project. The purpose and objective of this work was to: 1. Collect additional water quality samples, perform discharge measurements, and document measurement point conditions at 5 submerged spring vents of the Silver Springs Group and in the Silver River as part of the Silver Springs Characterization Project. 2. Provide submerged spring point documentation of groundwater discharges at one location in Blue Spring Run (Volusia County), three areas in the Silver River, and as many sites that could be visited for locations identified in the Wekiva River, Crescent Beach Spring, Shands Bridge Spring, the Rodman Reservoir and Ocklawaha River, Lake Harris and near Driggers Island in the St. Johns River.
