Evaluation of phosphorus loading following a manure spill and an in-stream sediment amendment to reduce phosphorus desorption

Major Goals and Objectives

  • 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
