Abstract

- PCB concentration in river water at the outlet of a lake was monitored far two years following the completed remediation of the PCB contaminated sediment of the lake. The remediation resulted in lowered PCB concentration in the sediment, from 5 mu g g(-1) (d.w.) to 0.060 mu g g(-1) (d.w.). PCB concentration in the water decreased over the two years, but varied seasonally. Highest PCB concentrations were recorded in summer. PCB concentration was positively correlated to temperature. Spring and winter values of PCB concentration were positively correlated to water discharge and to suspended matter probably originating from resedimented particles during remediation, PCA analysis of congener patterns in the water supported this conclusion. The seasonality in PCB concentration and congener distribution seemed to gradually become similar to a location upstream of the contaminated lake.
