A spatio-temporal study of methylmercury biogeochemistry in wetlands of the southern Lake Michigan watershed

Major Goals and Objectives

  • Measure the levels of total mercury (Hg) and methylmercury (MeHg) in the surface waters of wetlands across the Grand Calumet region of northwestern Indiana
  • Measure the concentrations of total and MeHg in wetland sediments – the main repositories for legacy Hg contamination in these wetlands
  • Measure the concentrations of total and MeHg in porewaters of wetland sediments – the main route for MeHg transport from the sediments to the overlying waters – in the region
  • Assess the MeHg levels in fish from wetlands with permanent open water
