Cooperator: Wisconsin Department of Natural Resources
Project Chief: Peter E. Hughes
Location: City of Milwaukee
Project Number: 9KO15
Period of Project: June 2001–June 2003
Problem
The Wisconsin Department of Natural Resources is evaluating alternatives for removing PCB-contaminated sediments from the Estabrook Impoundment on the Milwaukee River. Lincoln Creek empties into this impoundment and it is important to identify if there are continuing sources of PCBs coming from Lincoln Creek drainages.
Objective
The primary objective of this study is to collect water-column samples during runoff events to quantify the PCB load being transported in Lincoln Creek.
Approach
The USGS will establish a gaging station on Lincoln Creek at 27th Street and install equipment to automatically collect water samples during runoff events. A total of 19 event composite samples will be collected and processed for analysis by the Wisconsin State Laboratory of Hygiene for particulate and dissolved PCBs. A total of 110 discrete suspended solids samples will also be analyzed. Streamflow will be continuously monitored and used to compute the PCB and suspended solids loads transported during runoff events.
Progress (July 2003–June 2004)
Sample collection was completed and laboratory data has been received. Preparation of a data summary is in progress.
Plans (July 2004–June 2005)
A data report will be prepared which will summarize the PCB and suspended solids concentrations for the monitored events.
Reports
Data report is pending. |
