Description
Summary:This report represents the second phase of a 3-year (three-phase) project that the Wisconsin Department of Natural Resources (WDNR) requested from the St. Paul District as planning assistance under Section 22 of the Water Resources Development Act of 1974 (Public Law 93-251). The State of Wisconsin is interested in identifying appropriate bioassessment testing methodologies for the regulatory testing of freshwater sediments scheduled for dredging and open- water disposal. The report includes discussions and recommendations for specific approaches to bioassessment methods in the tiered testing protocol. The methods described in this report have the potential to be the most frequently used testing techniques, and represent the backbone of the tiered testing evaluation for regulatory testing of freshwater sediments.
