Goal Quantify sediment and toxic chemical loads associated with upstream sources in the Green River to the Lower Duwamish Waterway LDW. Focus is on high flowhigh turbidity events that may contribute more to the annual loading than average flow conditions. These improved measurements will aid in assessing the potential for future re-contamination of remediated sediment in the Lower Duwamish Waterway.
