Coal Creek

In 1994, a US unit was used to remediate PCBs at the Coal Creek Superfund Site in Chehalis, Washington. Approximately 33,000 tons of soils were excavated, and highly contaminated soils were separated from soils with minimum contamination. Approximately 9700 tons were treated with the nS-5 the remaining soil was stabilized and backfilled into an in-site containment cell (D115377). The actual cost for remediation at the site was approximately 8,100,000, or approximately 830 per ton. The extensive excavation and material handling at the site added to the total remediation cost (D184672, p. 77).

For instance, in 2014, the local water conservancy district wanted to pump the water from Lake Quitchipa to a new percolation bed to allow the water to enter the local aquifer. Three students were assigned to this project. They collected water samples at different locations in the lake at different times. They measured total dissolved sohds of the samples they collected. They also measured the anions and other analytes in the lake. They determined the TDS concentrations at the Met (Coal Creek) to be approximately 400 mg/L and over, 6000 mg/L in the lake. They came to the conclusion the water was too salty due to the many years of evaporation. With this information, the conservancy district abandoned the project.
