SAN LEANDRO, CALIFORNIA 94577 Cleanup Program Site Case No. RO0003448 Summary – This fact sheet has been prepared to inform community members about environmental activities being conducted at the Marina Village Shopping Center at 2250 Marina Blvd. in San Leandro (Site). 3156 24th Street, LLC, the property owner, is working under the oversight of the Alameda County Department of Environmental Health (ACDEH) to voluntarily investigate and clean up solvents that were released to soil and groundwater from former dry cleaners that operated on the property. This fact sheet contains information on the Site, environmental investigations and mitigation measures completed, and next steps. Site Background – The Site is located at Marina Boulevard and Doolittle Drive in San Leandro and is surrounded by residences to the west and south, retail to the east, and residences and industrial buildings to the north. The Site consists of two commercial buildings, containing six businesses and has historically been used for retail. From the 1960s to the 1980s, the Site had various dry-cleaning businesses which have resulted in releases of dry-cleaning solvents to the underlying soil and groundwater. Environmental Investigations – Multiple investigations have been conducted at the Site since 2021. These investigations have identified elevated concentrations of tetrachloroethene (PCE) in soil, soil vapor (the air spaces between grains of soil), groundwater and indoor air. Recent investigations have documented PCE in indoor air in building tenant spaces that has migrated from the subsurface through the building foundations in a process called vapor intrusion. Next Steps – Environmental consultants representing the owner of the Site will be conducting the following work: • Further sampling of soil vapor and groundwater on Site. • Conducting off-Site investigations to determine if contamination is present in groundwater and soil vapor. • Developing interim mitigation measures to reduce vapor intrusion risk to on-Site tenants. • Developing a cleanup plan to address contamination and ensure the long-term protection of public health and the environment. Mitigation Measures – While a long-term cleanup plan is being developed, the owner of the Site will be implementing mitigation measures, which are intended to lessen the impacts of vapor intrusion to on-Site tenants. These measures may include installation of air purifiers into building tenant spaces, modification to the heating and ventilation systems for the buildings, and installation of engineering controls to prevent soil vapor from entering the buildings on- and off-Site. For More Information – For more information, please contact Tracy Craig, Community Outreach, (510) 334-4866 or tracy@craig-communications.com. ACDEH will send out additional fact sheets to notify tenants and the community of additional investigation activities and cleanup and mitigation measures being considered for approval by ACDEH.
