Abstract:

The objectives of the MARC FSI were to Determine if the Reserve Center is the source of low-level trichloroethylene TCE contamination i.e., 5 to 9 micrograms1 detected in a nearby Ranney collector well Collector B operated by Manitowoc Public Utilities MPU and to determine if 1,2- dichloroethane contamination detected in MARC Well MW-6 by E. C. Jordan Co. Jordan has migrated off site toward Collector B. TCE was not found on site in any sampled soils or groundwater. However, very low concentrations i.e., just above certified reporting limits CRLs of four VOCs were found in groundwater in the vicinity of the septic tank drainage field. These included 1, 2-dichloroethane, 1,1-dichloroethane, 1,2-dichloroethane, and tetrachloroethylene. Only one VOC, 1,2-dichloroethane, was detected at the same well MW-6 in both rounds of groundwater sampling. This compound is not a transformation product of TCE, nor can it be transformed to TCE by natural processes.
