Quantifying estrogen compound and nutrient reduction in a coupled wetland and groundwater flow-through system

Principal Investigator: Eric Peterson
Affiliation: Illinois State University
Initiation Date: 2010

• 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

Nutrient fluxes in tile drains and ditches draining Midwestern agriculture fields fertilized with manure

Principal Investigator: Chad Jafvert
Affiliation: Purdue University
Initiation Date: 2010

• 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

Principal Investigator: Acushla Antony
Affiliation: Purdue University
Initiation Date: 2010

• 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
