This metadata record describes data collected from laboratory experiments designed to characterize the microbial processes that contribute to clogging (i.e., bioclogging) of wells used for recharge (i.e., injection) of fresh surface water into specific aquifer zones (Upper Floridan Aquifer [UFA] and Avon Park Permeable Zone [APPZ]) as part of water storage technology of aquifer storage and recovery (ASR). Solid rock core samples were collected from three wells (ASRC38S, ASRL63S and ASRC59; abbreviated to ...
