Title: Evaluation of the Potential For Restoring Commercially Viable Oyster Harvesting in Suwannee Sound
This study examined the pre- and post-construction Salmonella occurrence, and fecal coliform, nitrate/nitrite, and total Kjeldahl nitrogen concentrations in the Suwannee River near the Town of Suwannee and canals in the town to evaluate whether a project converting 850 septic systems to sewer would restore the commercial oyster harvesting in the Suwannee River. Post-construction monitoring was influenced by different weather conditions. Salmonella source was upstream of town.

Title:Nitrogen Impact of Onsite Sewage Treatment and Disposal Systems in the Wekiva Study Area June 30th, 2007
This study was requested by the legislature in 2006 to assess whether onsite sewage treatment and disposal systems (OSTDS) are a “significant source of nitrogen to the underlying groundwater relative to other sources” within the Wekiva Study Area (WSA) and, if so, “to recommend a range of cost-effective nitrogen reduction strategies.” The study included four tasks: (1) conduct groundwater monitoring on three OSTDS, (2) evaluate the influence of soil on OSTDS nitrogen load to groundwater, (3) estimate the OSTDS input and load contribution compared to other sources using the results from (2), and (4) assess a range of nitrogen reduction strategies. Recommendations to Florida legislature were provided to reduce nitrogen input from onsite systems in the Wekiva Study Area.
