• All 10 monitoring wells installed by iEP were sampled for VOCs in July and October 1988
• No VOCs were detected in any of the wells except B2
• iEP concluded that the low levels of TCE and toluene in B2 were most likely attributable to a nearby septic system
• Method 3 Risk Characterization prepared by Weston & Sampson Engineers, Inc. in 2001 for the Town of Holliston Marshall Street Landfill
• An elevation survey of 4 wells located in the vicinity of the landfill, indicated that groundwater flow is easterly toward the wetlands
• VOCs were not present above detection limits, except for 1,2,4-trimethylbenzene which was detected in only one of the wells
