<br />- A description and list of potential human and/or environmental exposure <br />pathways pertinent to the current and potential future use of the property. <br />This is important in assessing exposure risk as part of the overall <br />evaluation of the proposed corrective action. <br />Table IV B5 - Receptor Pathwav Evaluation <br />Source Area Potential Environmental Potential Human <br /> Exposure Pathways Exposure Pathways <br /> SHT contains very high BTEX <br /> levels; Dermal <br />Slurry Holding Trench Area will be used for human Inhalation <br /> recreation (biking, hiking, Ingestion <br /> fishing) <br /> Limited subsurface soil <br /> impacts are present beyond <br /> the SHT and incomplete slurry Dermal <br />Subsurface Soil wall; Inhalation <br /> Area will be used for human Ingestion <br /> recreation (biking, hiking, <br /> fishing) <br /> Groundwater is expected to <br /> be impacted where the SHT <br /> and incomplete slurry wall <br /> was excavated below 6 feet <br />Groundwater bgs; Ingestion <br /> Groundwater is not expected <br /> to be used for irrigation or <br /> domestic/agricultural water <br /> supply <br /> There is the potential for <br /> impacts to the St. Wain River <br /> as is appears the groundwater <br />Surface Water aquifer in the area of the Dermal <br /> pipeline release are in Inhalation <br />(St. Vrain River) communication; Ingestion <br /> Surface water features will be <br /> used for human recreation <br /> (fishing, swimming, boating) <br /> There is the potential for <br /> impacts to the quarry ponds <br /> as it appears the groundwater <br />Surface Water aquifer in the area of the Dermal <br /> pipeline release are in Inhalation <br />(Quarry Ponds) communication; Ingestion <br /> Surface water features will be <br /> used for human recreation <br /> (fishing, swimming, boating) <br />16
