Current Projects

Ballast Water Treatment (2005 - present)

A study examining the effects of ballast treatment technologies to minimize the potential introduction of exotic species such as zebra mussels, ruffe, and goby by commercial ships. LSRI has obtained a docking facility, an anchored barge, and is currently constructing a pumping facility for the ballast water treatment project. This will allow for the replication of ballast water intake, treatment, and release procedures as actually done in an industrial setting. The purpose is to determine what ballast water treatment techniques work best to eradicate exotic species, while providing a realistic economical, timely, and environmental solution.

Chemical Monitoring of Fish Tissue, Wild Rice, and Mussels (1990s - present)

A systematic sampling of fish, wild rice, and mussels from the Upper Midwest lake and stream areas to determine metal concentrations in their tissues, and help establish safe consumption levels for humans. Samples are measured for mercury content and PCB levels.

Effects of Pollutants on Aquatic Macroinvertebrates (1990s - present)

This study has included leaching landfills in two different cities in Wisconsin, deicing compounds used at Milwaukee's airport, pollutants located at U.S. EPA Superfund sites, and numerous other sites contaminated with various pollutants.  An ongoing study involves the continual monitoring of the recovery of a stream in Superior and bay within Lake Superior that have been impacted by industrial pollutants for many years until each was recently reclamated by the State.

Field Surveys of Rare and Endangered Aquatic Macroinvertebrates (1990s - present)

Surveys of rare and endangered aquatic macroinvertebrates on state-owned land in Wisconsin.  Tracts have included state forests such as the Northern Highland/American Legion, Brule River, Black River, Flambeau River, and Peshtigo River.  Other state areas included the Wolf River Watershed, Meadow Valley Central Lowlands, the Lake Superior Watershed, and the Door County Peninsula.

Survey of Native and Invasive Plants of Publicly-Owned Property (2005 - present)

This project will document the status of rare native plants in the Apostle Islands, and potentially destructive invasive plants that occur in the Brule River and Governor Knowles forests.  Control measures will be implemented on the invasive plants as part of the completion of the project.
