Bay Road Holdings LLC (formerly Romic Environmental Technologies Corp.) is a closed hazardous waste management facility located in East Palo Alto, Calif., near the San Francisco Bay. The facility ceased operations in 2007, and all surface structures were demolished in 2009. Historical facility operations from 1964 to 2007 included solvent recycling, fuel blending, wastewater treatment, and hazardous waste storage and treatment, resulting in releases that contaminated the soil and groundwater beneath the site. Biological treatment was the primary remedy selected by EPA to address the solvent-contaminated soil and groundwater. The biological treatment approach introduces a substrate (cheese whey and molasses were used in early testing) through horizontal injection wells (>200 ft long) for distribution via an in situ delivery (ISD™) groundwater recirculation system. The horizontal injection wells and the biological treatment system can operate independently and thus not interfere with the redevelopment ongoing at the surface. See details of this system in the ISD™ Groundwater Recirculation Pilot System Installation Work Plan at https://www.epa.gov/sites/production/files/2017-09/documents/former_romic_facility_final_groundwater_recirculation_pilot_system_installation_workplan-2016-09.pdf. About 40% of the biological treatment system was constructed and underwent testing in 2017. A full-scale treatment system is expected to be in operation by 2020.
