• Develop a comprehensive understanding of P and NH4-N partitioning between fluvial sediments and the overlying water column during and following a manure spill
• Determine the effectiveness of the current manure spill remediation plan to mitigate P desorption from manure exposed ditch sediments
• Investigate the influence of sediment particle size distribution on the depth of P contamination as a result of a manure spill under base flow conditions
• Determine adequate application rates of alum and CaCO3 needed to remediate fluvial sediments following a manure spill
• Evaluate the efficacy of the sediment alum treatments following a manure spill

• Evaluate the polyculture of yellow perch in cages with freshwater prawns in ponds.
• Evaluate the effect of culture temperature on growth and survival of yellow perch.

• Isolate and grow previously unculturable aquatic microorganisms
• Evaluate extracts for anticancer and anti-tuberculosis activities
• Evaluate extracts for anticancer and anti-tuberculosis activities

• Count zooplankton already collected from Green Bay
• Contribute to a lakewide understanding of mechanisms limiting recruitment of yellow perch
• Provide information useful to fisheries managers

This project will address an emerging issue along the coast of Lake Michigan in Northwest Indiana: microbiological pollution of beach sands due to failing septic systems. We will sample beaches in areas of known septic system failures and the sand for E. coli, human fecal bacterial DNA markers, and common pathogens. Successful execution of this project will result in data that can be used for a quantitative microbial risk assessment (QMRA) for beachgoers in the area and an experimental framework that can be expanded to examine beach sands in other Indiana coastal communities with high densities of shoreline septic systems.

• Explore application of a new enabling technology to aquatic food web dynamics
• Assess whether organisms within trophic levels have unique chemical/nutrient compositions
