  • Dataset Abstract
    This research investigated the effects of the vegetation and soil removal on the hydrologic conditions of the Hole-in-the-donut (HID) of Everglades National Park. Groundwater and surface water samples were collected from 2 wells within the HID (DO1,DO3) and two wells outside the HID in adjacent Taylor Slough (NP-67, TSB). Surface water was collected at each site if present.

    Description
    Groundwater and four surface-water was collected from four sites DO1, DO3, NP-67, and TSB. The sites were sampled four times: in December 2015 and in May, September and December 2016. Wells DO1 and DO3 were located within two re-stored parcels of the HID wetland, while wells NP-67 and TSB were in wetland areas outside of the HID. Wells DO1, DO3, and NP-67 were encased in PVC pipe and circumscribed into wooden platforms fitted with metal covers. Well TSB was flush mounted with the ground surface and protected at the surface by a metal cover. The installation and depths of the three wells varied: DO1 was 7.5 meters deep and installed in 1989; DO3 was 3 meters deep and installed in 2000; NP-67 was 5.6 meters deep and installed in 1960; TSB was 4.1 meters deep and installed in 1997.
    To collect groundwater and surface-water samples in the field, a gas-powered pump was used to purge three well volumes before sampling and then a peristaltic pump was used to collect the samples. If present, surface water samples were collected adjacent to each well. At each sampling location, two samples were filtered through a 0.45 μm membrane filter, and two unfiltered samples were collected and stored on ice at 4°C and transported to Florida International University (FIU) for final storage. Samples for total phosphorus and cations were preserved with 10% hydrochloric acid.

    Instrumentation
    The Nutrient Analysis Laboratory at FIU analyzed the groundwater and surface-water samples for total nitrogen (TN) using an Antek TN analyzer (Antek Instruments, Houston, Texas, USA), and total organic carbon (TOC) using a Shimadzu TOC-V, Analyzer (Shimadzu Corporation, Columbia, Maryland, USA). Total phosphorus (TP) was analyzed following Solórzano, L. and Sharp, J.H. (1980). The FIU Soil/Sediment Biogeochemistry Laboratory analyzed the groundwater and surface-water samples for soluble reactive phosphorus (SRP), nitrate (NO3), and ammonium (NH4) using an Alpkem Rapid Flow Analyzer with 2-Channel ER Detector. The FIU Hydrogeology Laboratory analyzed the groundwater and surface-water samples for total alkalinity using a Gran titration method with a Brinkman TitrinoTM 751 Titrator. As the pH of the water samples varied between 6.02 and 7.69, the total alkalinity results were reported in mg/L of HCO3-. Major anions (chloride [Cl-] and sulfate [SO42-]) and cations (calcium [Ca2+], magnesium [Mg2+], sodium [Na+], and potassium [K+]) were determined using a Dionex-120TM Ion Chromatograph.
