Since July 2014, the San Francisco Bay Regional Water Quality Control Board <br />(“RWQCB”) has provided direction to the City of Redwood City Public Works Services Department (PWS) <br />on how to monitor and remedy the groundwater contamination. <br />As requested by the RWQCB, from February through April 2023, the City conducted remedial activities on <br />the site for chlorinated solvents in groundwater. Quarterly groundwater monitoring paused during the <br />remedial activities and resumed in the second quarter of 2023. Results show contamination in the <br />groundwater has significantly decreased, and at this time, the RWQCB is requesting a soil vapor <br />investigation to be conducted for the site to make progress towards case closure. <br />8.D. - Page 1 of 22 <br />36
