Abstract |
The Ott/Story/Cordova site is in Dalton Township, Muskegon County, Michigan. Beginning in 1957, various specialty organic chemical manufacturers operated at the site, producing intermediate items used in making pharmaceuticals, dyestuffs, and agricultural chemicals. Soil and water contamination was noted as early as the 1960s, probably resulting from discharge of production vessel clean out wastes and wastewaters to onsite unlined lagoons, and drums of waste that were accumulated onsite. Due to the complexity of the site the cleanup will be organized into two distinct operable units. The first operable unit addresses the interception of contaminated groundwater entering the Little Bear Creek system. The second operable unit will address contaminated soil, possible groundwater remediation, source control, and air and water monitoring. The primary chemicals of concern affecting the groundwater and surface water are VOCs including benzene, PCE, TCE, toluene, vinyl chloride, and xylene; other organics including PCBs and pesticides; and metals including arsenic. The selected remedial action for this site are included. |
