A GE 4 Land use The 1325 and 1515 West Weber properties are located in an industrial area of Stockton,California Both properties have historically been used for industrial purposes and both are zoned for heavy industrial use ERM is not aware of any plana to change the zorting of these properties in the foreseeable future Sod Based on land use information for the su*ct properties and the absence of residual soil constatuents in surface soils,there is little or no opportunity for exposure to xestdual soil constituents under conditions associated with the industrial use of these sites Specific points regarding potential exposure are noted below e Because residual soil constituents are confined to the subsurface, industrial workers at the sub�ect properties are unlikely to be exposed to soil cornststuents vza direct contact (i.e,incidental ingestion and dermal contact) . © Sia laxly,because soil constituents are confined to depth,industrial workers are unlikely to be exposed to residual soil constituents via the irnhalation of fu ave dust Q Only isolated deteclsoras of volatile organic compounds (VOCs)3 are present in subsurface soils Because of the very limited detections,the migration of these compounds from soil into air is not expected to represent a significant:exposure pathway for industrial workers. However, constructicri workers or others involved in 11-awsive subsurface activities at the site may be exposed to residual constituents in subsurface soils Under this scenario,exposure may occur via the following routes ® Inciderntal.ingestion. o Deruml contact. o Inhalatioin of VOCs released froi n sails that are exposed cluing excavation or other intrusive activities e VOCs detmc m soil include the aromatic hydrocarbons benzene,toluene, ethylbenzene,and xylenes.
