- Investigate the reduction of 17β-estradiol (E2) and Estrone
(E1) in treated wastewaters that were subjected to a tertiary treatment composed of a coupled wetland and ground water flow through system - Quantify the presence of E2 and E1 in treated wastewater and along ground water pathways from a wetland
- Determine the potential reduction of E2 and transformation of E2 to E1 along the ground water pathways
- Expand upon the results by Peterson and Lanning (2009) showing the effectiveness of wetlands as a treatment for E2 removal
- Use the pilot data gathered to develop a more thorough assessment of the wastewater treatment process

Trace organics in Lake Michigan: concentration and detection frequency of pharmaceuticals in the near-shore water column
- Quantify pharmaceutical abundance in near-shore Lake Michigan habitats by addressing the question: How do pharmaceutical concentrations vary spatially along the Indiana-Illinois shoreline of Lake Michigan?
Contaminant transport by introduced Pacific salmon to Great Lakes tributaries
- Quantify contaminant levels in salmon and stream-resident fish at three sites at the southern end of Lake Michigan
Modeling the effects of land use/land cover change on surface water quality within the Chicago MSA
- Explore the relationship between land use structural complexity and surface water quality
- Assess the role of seasonal differentials on surface water quality
- Explore the implications of future land use and climate changes on surface water quality
Nutrient fluxes in tile drains and ditches draining Midwestern agriculture fields fertilized with manure
- Calculate the loads of 17α- and 17β-estradiol, estrone, and estriol, nitrate, and dissolved reactive phosphorus exported from a subsurface tile drain and a receiving ditch
- Compare the export dynamics of nutrients and hormones in response to animal waste applications
- Assess the potential for nutrient best management practices (e.g., no-till, buffer strips, wetlands, etc.) to reduce hormone export from tile-drained agroecosystems
A web-based tool to measure environmental quality standards for phosphorus in water at Lake Erie
- Enhance the NAPRA online web-based decision support tool and update the soil database using SSURGO soils data suitable for field and county level evaluation
- Assess the level of phosphorus reaching water with existing cropping management systems and assess the change in phosphorus level due to increases in biofeedstock production and intensive livestock production
