Personnel and Role: Aimee B. Fratarcangeli, P.G., Project Manager

Services Provided:

HydroDesigns, LLC participated in the acquisition of the original Florida Department of Environmental Protection (FDEP) Class I injection well construction and testing permit. This involved the acquisition of area of review well data, determination of the geology/hydrogeology of the area, design of the injection and monitoring wells, testing during drilling (cuttings, cores, borehole geophysics, straddle packers, pump and injection tests, MIT’s, and water quality), and responding to FDEP requests for information (RFI’s). The injection well was constructed to 2,906 feet bls and the multi-zone monitoring well to a total depth of 1,905 feet bls both penetrating the Floridan Aquifer System. HydroDesigns provided good construction oversight and reporting to the Services District and prepared the final Construction and Testing Report for FDEP. During construction daily site activities were recorded (drilling rates, mud weights, casing installations, pressure testing, straddle packer testing, water quality sampling, geologic interpretation of cuttings and cores, interpretation of geophysical logs, and aquifer performance testing for hydraulic characteristics and pump sizing were also performed. This facility has obtained an operating permit for the injection well system and conducted three MITs (5 years). The second and third MITs were performed in May 2015 and May 2020.
