[email protected] Pathways, Components, or Threats Not Scored The Dwyer Property Ground Water Plume site is being evaluated as an area of ground water contamination with unknown sources. Preliminary scores for the surface water migration, air migration, and soil exposure pathways indicated minimal contribution of these to the overall site score; therefore, these pathways have not been included in this HRS documentation record. The surface water migration pathway ground water to surface water component score was low due to the lack of hazardous substances with high bioaccumulation factor values. Additionally, an overland runoff pathway likely does not exist. The lack of documented observed contamination and resident targets limit the soil exposure pathway scores. No observed release to the air has been documented within a 4-mile radius of the ground water plume. Surface Water Overland Migration Pathway The surface water pathway was not scored. The ground water pathway was sufficient to list the site. Soil Exposure Pathway The soil exposure pathway was not scored. The ground water pathway was sufficient to list the site. Air Migration Pathway The air migration pathway was not scored. The ground water pathway was sufficient to list the site.
