Johnson Engineering Presents at Annual FSA Conference

Thursday, October 3rd, 2019

Scientists, engineers, managers, policy makers, and elected officials gathered in June for the 2019 Annual Florida Stormwater Associations (FSA) Conference, themed A Change in Climate – FSA: the Next 25 Years.

Johnson Engineering’s Sr. Environmental Scientist, Tim Denison co-presented on two studies titled “Why are the Bacteria Counts in my Stream still so High?“ and “Septic System Impacts on Stormwater and Impaired Waterbodies.”

For the first presentation, Tim and Sarasota County’s Neighborhood Environmental Stewardship Team (NEST) Coordinator, Mollie Holland, discussed “Why are the Bacteria Counts in my Stream still so High?” They demonstrated how they designed and implemented a Microbial Source Tracking (MST) plan to help determine possible causes of elevated bacteria concentrations impacting the Phillippi Creek basin, which has been issued a Total Maximum Daily Load (TMDL).

During the second presentation, “Septic System Impacts on Stormwater and Impaired Waterbodies,” Tim presented along with Tetra Tech’s Sr. Water Resources Engineer Marcy Frick. The duo explained their findings of water quality benefits to stormwater, groundwater, and surface waters for the Spring Lakes area in Charlotte County following the County’s recent large-scale septic system removal project.
