Microbial removal of nitrogen and phosphorus from surface water recharged into the Upper Floridan Aquifer

Release Date:

A recent study is providing novel data on the ability of microorganisms to remove nutrients during storage at aquifer storage and recovery (ASR) facilities near Lake Okeechobee.

Dr. John Lisle (Research Microbial Ecologist, SPCMSC) is currently being funded by South Florida Water Management District (SFWMD) to characterize the rates of microbial removal of nitrates, nitrites, ammonium, and phosphorus from treated water from the Kissimmee River that will be recharged into the Upper Floridan Aquifer (UFA). This study is providing novel data on the ability of microorganisms native to the UFA and introduced in the treated recharge water to remove nutrients during storage at aquifer storage and recovery (ASR) facilities near Lake Okeechobee. The data from this study are being considered by state regulatory agencies for assignment of water quality improvement criteria to the storage phase of recharged water at ASR facilities. Dr. Lisle presented a webinar to South Florida Water Management District (SFWMD) personnel in West Palm Beach, Florida, and Florida Department of Environmental Protection (FL DEP) personnel in Tallahassee, Florida, describing recent research findings on the removal of nitrates, nitrites, and phosphorus from recharged water during the storage in the Upper Floridan Aquifer.
