Cleanup and Site Remediation

Overview of Site Assessments

Due to its historic use as a rail yard for over 80 years, the soil at the G2 Parcel is contaminated and the site is designated as a "brownfield". This contamination is being dealt with through a robust remediation strategy.

Site Assessments are one component of the Remediation/Clean-Up process. A Site Assessment provides basic information for determining if there has been a release of hazardous material at a site, or if a naturally occurring hazardous material that presents a risk to human health or the environment may be present. A Site Assessment is conducted under the oversite of a regulatory agency to identify the type, amount and extent of contamination. The Remediation/Clean-Up process includes different components as displayed on the graphic. The final stage of the process is the clean-up phase which ensures that there are no risks to human health or the environment.

Site Testing on the G2 Parcel

Site Assessments fieldwork began on June 4, 2018 and was completed on September 21, 2018.

A total of 452 soil gas readings were taken at various depths in 228 locations throughout the site. A total of 645 soil samples have been collected from various depths at 78 locations. 14 small test pits were also excavated to more closely investigate areas of concern based on visual and geophysical observations. A draft Phase II Environmental Site Assessments Report based on the completed fieldwork and laboratory analysis of samples was submitted to DTSC on November 30, 2018 for their review.

All testing was completed in accordance with a site-specific Work Plan and Health and Safety Plan approved by the California Department of Toxic Substances Control (DTSC), the overseeing regulatory agency. The primary goal of these plans is to assure the safety of nearby residents, schools and parks, our workers, and our environment.
