DNRP, Lower Duwamish Work Group begin Activated Carbon pilot study

An innovative sediment cleanup technology is being tested by the Lower Duwamish Work Group. Activated Carbon, common in household water filters, was placed on three plots in the Lower Duwamish. Three years of monitoring now begins to evaluate the effectiveness of Activated Carbon in trapping contaminants and the effects the filtering has on organisms living in the sediment.

The Lower Duwamish Waterway Group is composed of specialists from King County, the City of Seattle, the Port of Seattle and the Boeing Company. The County’s Wastewater Treatment Division constructed the pilot project and is contracting the monitoring work on behalf of LDWG.
