Cooperator: Menominee Indian Tribe of Wisconsin
Project Chief: Faith A. Fitzpatrick
Location: Neopit, Menominee Indian Reservation
Project Number: 9K039
Period of Project: February 2001–September 2005
Problem
A dam at the Neopit Mill Pond, Neopit, Wisconsin, Menominee Reservation, may be removed and the Menominee Indian Tribe needs information on the volume, texture, and chemistry of sediment stored in the mill pond behind the dam. A preliminary study was completed in 2003 and elevated concentrations of semi-volatile organic compounds (SVOCs) were detected in sediment from the mill pond. Additional sampling for SVOCs in the mill pond sediment is needed to determine spatial extent of possible contamination.
Objective
The project objective is to determine the spatial distribution of SVOCs in the Neopit mill pond sediment.
Approach
Approximately 15 sediment cores will be collected from the Neopit mill pond in the summer of 2004. Samples from the cores will analyzed for SVOCs, dioxin/furans, organic carbon, and particle size. Approximately 10 percent of the samples will be submitted for quality assurance.
Progress (July 2003–June 2004)
The project for additional sampling began in October 2004. A QAPP was written. Labs were selected for SVOC and dioxin/furan analyses.
Plans (July 2004–June 2005)
Cores will be collected in August and submitted and for
analyses. Data will be analyzed. |
