Document Description
DTSC pursuant to authority granted under Chapter 6.8, Health and Safety Code Section 25395 approved a Response Plan which describes activities to address soil and groundwater contamination existing at the former Southland Steel facility (Site). The proposed response consists of the following activities: 1. Soil Excavation. Between 1,900 and 4,000 cubic yards of soil containing PAHs, arsenic, lead, and volatile organic compound (VOC)-impacted soil will be excavated using a front-end loader and backhoe to achieve the Site's Commercial / Industrial cleanup goals. The anticipated depth of excavation is between two and five feet. 2. Installation of Excavation Area. Following successful completion of the removal action, excavated areas will be backfilled with a like volume of clean soil. 3. Installation of Groundwater Monitoring Wells. Two groundwater monitoring wells will be installed on the eastern side of the property along Alameda Street, one located to the western side near the railroad right of way, and one groundwater monitoring well located south of the property boundary. These wells would be sampled along with the four existing groundwater monitoring wells and would serve to identify groundwater flow and gradient at the Site. These wells would be monitored twice prior to determining VOC contribution to groundwater from the Site. Installation of Groundwater Treatment System if deemed necessary by DTSC, an in-situ de-chlorination groundwater treatment system will be installed and operated to treat any VOC contaminants in groundwater beneath the site. This process will destroy the contaminants in the groundwater by injecting a chemical directly into the area, monitoring will be conducted to ensure the effectiveness of the treatment. Injection chemicals such as Calcium Polysulfide and Potassium Permanganate may be used as injection fluid for the treatment process. This system consists of injection wells and will use existing monitoring wells.
