| Abstract | The South Tacoma Channel, Well 12A is in the City of Tacoma, WA, and lies within the Commencement Bay drainage area. In Sept. 1981, Well 12A was voluntarily removed from service by the city when chlorinated organic solvents were detected. During 1982, volatile organics were discovered in nearby Well 9A which was also closed. A ground water study confirmed that should the contaminated wells closest to the source remain shut down, pumping of the other production wells would draw the contaminated plume throughout the well field. The cost-effective Initial Remedial Measure (IRM) is to pump and treat water from Well 12A. Pumping of the well will assist in confining contaminant movement within the aquifer. Air stripping will occasionally allow the city to use the water when its quality is acceptable. The cost of the project is estimated to be $1,200,000. Operation, maintenance, and monitoring costs are estimated to be $60,000 annually. |
