Project Overview

Under contract with Leon County, ATM has provided ongoing support in the assessment of the causes of impairment in Lake Talquin. Work has included water quality sampling to identify pollutant loads to the system, analyses of the watershed and receiving water hydrologic and water quality data, and technical review of models and analyses supporting the development of the TMDL for Lake Talquin. The models included the LSPC model for watershed loadings, the EFDC model for receiving water hydrodynamics and the WASP model for receiving water quality. Work included the installation of the models developed by EPA, detailed review of all model inputs, identification of model modification and issues relative to the calibration. ATM worked in close cooperation with FDEP as well as EPA and provided significant input on how to update and strengthen the system of the model’s technical defensibility.
