An Investigation of Microplastics as a Carrier for Perfluorinated Compounds into Great Lakes Food Webs

Principal Investigator: John Scott
Affiliation: Illinois Sustainable Technology Center
Initiation Date: 2018

This project aims to investigate the potential role of marine plastic debris as a vector for Perfluorinated Compounds (PFAS). Specific research questions are:

  • To what extent do three common plastic types found in the environment act as a sink for select PFASs in Muskegon Lake?
  • How important is the residence time of the materials present in these water bodies concerning the extent of PFAS accumulation?

 


Methods Development to Predict Establishment Risk of Emerging Freshwater Invasive Species in the Great Lakes Basin

Principal Investigator: Eric Larson
Affiliation: University of Illinois Urbana-Champaign
Initiation Date: 2018

This project aims to demonstrate the potential to use well-quantified niche shifts from established ‘avatar invaders’ to develop plausible distributions for similar emerging invaders. The study uses the red swamp crayfish Procambarus clarkii as an ‘avatar invader’ and the yabby Cherax destructor, as a data-poor emerging invader.


New Approach in Replacing Live Food – Meeting Largemouth Bass Larvae Growth Requirements using Asian Carp Muscle as an Initial Protein Source

Principal Investigator: Karolina Kwasek
Affiliation: Southern Illinois University Carbondale
Initiation Date: 2018

The objectives of this project are:

  • To develop optimal in vitro methodology for Asian carp muscle hydrolysis using largemouth bass (LMB) endogenous digestive enzymes obtained from adult LMB.
  • To evaluate the effect of Asian carp muscle protein hydrolysates obtained using methodology in Objective 1 as a first feed for larval LMB.

Method Development for Analyzing Microplastics in Sediment of Lake Michigan

Principal Investigator: An Li
Affiliation: University of Illinois at Chicago
Initiation Date: 2018

Plastic contamination of the global environment has been widely recognized, but little information is available for the Great Lakes sediment. The objective of this project is to establish laboratory procedures for the analysis of microplastics in sediment of natural waters, and obtain preliminary data for Lake Michigan.


Failing Septic Systems as a Source of Human Pathogens to Beach Sand

Principal Investigator: Jenny Fisher
Affiliation: Indiana University Northwest
Initiation Date: 2018

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.


Improving the Simulation of Green Infrastructure to Include Flood Mitigation and Lifecycle Duration

Principal Investigator: Bernard Engel
Affiliation: Purdue University
Initiation Date: 2018

The objectives of this project are:

  • To determine the role of green infrastructure (GI) practices in reducing flooding by developing Long-Term Hydrologic Impact Assessment-Low Impact Development (L-THIA-LID) 2.2 models to simulate flooding (peak flow rate) and impacts of GI on reducing flooding.
  • To identify the long-term performance of GI practices in reducing flooding by improving the model algorithm to simulate GI practice efficiencies considering changes in performance of practices over time.
  • To enhance the optimization tool for selecting and placing GI practices to account for flooding.
  • To demonstrate the impacts of GI practice adoption on flooding through use of the improved model in analysis of potential and optimal GI impacts in the Washington Park community in Chicago.
  • To use the new tool to increase the understanding of impacts of GI practices in reducing flooding by providing outreach through tutorial and video instructional support including to community organizations around Chicago and classes at DePaul University and Purdue University.
