It is surprising that there has been so little interest in the clean up of the site and in the possible and probable leaking into Humboldt Bay. Danger to Humboldt Bay has been mentioned again and again in correspondence from the North Coast Water Board.
Enclosure A Technical Memorandum on the Geotracker Site says there are 26 monitoring wells. It says, "Full compliance was not achieved with MRP No. R1-2010-0023 provisions 3,4,5,7, and the reporting requirements, and hence represent violations of the California Water Code. " "The omission of DO (dissolved oxygen) does not comply...." Two sample results show TDS (total dissolved solids) above the level acceptable for drinking water. "...results identify the presence of 10 different types of CVOCs (PCE (perchloroethylene), TCE (trichloroethylene), 1,1-DCE (dichloroethene), cis-1,2-DCE, 1,1-DCA, chloroform, 1,1,1-TCA, vinyl chloride, chloroethane 1,2-DCE. " Furthermore, Water Quality Objectives were exceeded for PCE, TCE, 1,1-DCE, Cis-1,2-DCE, Chloroform and vinyl chloride. Most or all of these are on the proposition 65 list of chemicals known to cause cancer.
Dissolved metals of concern that were detected include arsenic, chromium, hexavalent chromium, manganese and nickel all known to cause cancer. "All of the measured concentrations exceed the shallow groundwater numeric WQO (Water Quality Objectives)." "Spatially, shallow groundwater regulatory thresholds are exeeded..." in 7 wells. Manganese is found is distributed throughout the site.
We will continue to follow the information on the monitoring and clean up.
