F <br /> leanup Activities a system was built to remove and treat <br /> ntaminated groundwater from the area. <br /> water is pumped from wells along Pacific <br /> and Inglewood Avenue. This system isstillin use today. <br /> I0. <br /> In 1999, a soil vapor extraction (SVE) system was <br /> built to remove PCE vapors from the soil beneath <br /> the shopping <br /> center. In 2007, the SVE system was <br /> expanded to include an air sparging component. <br /> Air sparging involves blowing air into the i c <br /> groundwater which forces the dissolved PCE in the <br /> groundwater up into the soil to be removed by the <br /> SVE system. , <br /> Approximately 11 tons of PCE have been removed Typical drill rt Installing from the soil and groundwater beneath the yp 9 g groundwatw monitoring well <br /> shopping center using these systems. <br /> Remaining Cleanup Effort <br /> Some low levels of PCE remain in groundwater east <br /> of the Lincoln Village Shopping Center that need to 9 <br /> be cleaned up. It is important to note that these it <br /> impacts do not pose a threat to any water <br /> consumers. We anticipate there will be 3 phases <br /> of work to complete the cleanup: <br /> Phase 1 Additional Investigation 1 <br /> Goal: Collect additional information about <br /> the extent and nature of PCE impacts <br /> in the off-site groundwater area. Groundwater sampling Collection Activities <br /> When.• Within the next 6 months(May- <br /> October 2012). <br /> Work: Drilling and installing groundwater <br /> monitoring wells; collecting soil and <br /> groundwater samples. Phase 3 Final Remedy <br /> Phase 2 Testing Goal: Implement final PCE cleanup remedy <br /> and monitor effectiveness. <br /> Goal: Test the effectiveness of potential PCE When: Final PCE cleanup implemented <br /> cleanup technologies. within next 3 years (by December <br /> When: Within the next 8 months(May- 2014),followed by performance <br /> December 2012). monitoring for 5-10 years. <br /> Work.• Install groundwater monitoring wells, Work: Final groundwater PCE <br /> Evaluate PCE cleanup technologies cleanup,continued groundwater <br /> and alternatives, collect groundwater extraction, groundwater sample <br /> samples. collection. <br /> For more information contact: <br /> • Geotracker website- <br /> https://geotrackei,waterboards cagov/regulators/screens/menu asp?global id=SL205132997 <br /> • Joe Niland, Lincoln Village Shopping Center Trustee: iniland(g)geosyntec com, (916)-637-8325 <br /> • Scott Forbess, Geosyntec Consultants: sforbess(Zi)aeosyntec com, (916)-637-8329 <br /> • Roberto Cervantes, Central Valley Water Board, rcervantes(o)waterboards ca gov, (916)-464-4682 <br />
