Water Quality

The nuisance algae, Lyngbya, which is proliferating in many of the freshwater coastal springs in Florida. We are studying what environmental factors are contributing to its’ growth.

Increased nutrient concentrations, especially nitrogen and phosphorus, degrade water quality and contribute to ecological problems such as algae blooms and fish kills. Wetlands and riparian areas serve as natural water filters by providing an environment that promotes the uptake and transformation of nutrients and other pollutants. We conduct research aimed at finding natural, cost-effective ways of utilizing ecosystem processes to address real-world water quality concerns.

Our work in water quality includes studying the efficiency of constructed wastewater treatment wetlands and natural wetlands at removing nutrients and other pollutants.  Currently, we are working at the Orlando Wetlands Park to evaluate the potential to impose period dry-downs in the treatment wetlands to promote soil consolidation and oxidation as a management technique for improving hydrologic efficiency and maximizing nutrient removal.

Our lab also conducts research evaluating the effectiveness of coastal restoration projects in mimicking the ecosystem services provided by natural systems.  Specifically, we are working with a team of interdisciplinary scientists to determine the ecological impact of oyster reefs and living shoreline restorations on both the natural and human system (e.g., how does engaging in ecosystem restoration impact the resilience of the environment and the local community?).  The ABL is spearheading the effort to determine the role of restored oyster reefs and living shorelines in sequestering, storing, and transforming carbon and nutrients that may otherwise contribute to coastal eutrophication.
