The East Multnomah County (EMC) project area refers to all areas in the EMC project area where the Troutdale Sandstone Aquifer (TSA) contains concentrations of halogenated volatile organic compounds at concentrations requiring remediation. The selected remedial action for the Troudale Sandstone Aquifer (TSA) contaminant plume includes: treatment of extracted groundwater using air-stripping treatment technology; discharge of treated groundwater to Fairview Lake and the Columbia Slough directly or via Multnomah County storm water drainage ways; abandonment of six private Sand and Gravel Aquifer (SGA) water supply wells located within the area of the TSA contaminant plume and a provision to replace the abandoned wells with an alternative source of water; institutional controls to restrict groundwater use of the TSA and SGA to prevent exposure to contaminated groundwater and the spread of groundwater contamination during remediation; groundwater monitoring to assess compliance with performance criteria established for the remedy; and hydraulic containment of those areas of the TSA for which it may be technically impractical to restor to MCL cleanup levels within 20 years.
