The City installed six stormwater treatment tree well units in its sidewalk planting strips in West Oakland. The project is part of a regional effort to monitor and implement pilot treatment activities for Poly Chlorinated Bi-Phenyls (PCBs) using EPA grant funds in partnership with the Bay Area Stormwater Management Agencies Association (BASMAA). The tree well units capture and filter stormwater runoff and will be monitored to determine how successfully they remove PCBs.
