Spotlight on Risk Based Remediation
Langan was retained to complete a human health risk assessment (HHRA) for a multi-acre site located in southern California. Prior to Langan’s involvement, several HHRAs had been completed to assess the nature and extent of potential human health risks associated with polychlorinated biphenyls (PCBs), mercury, and other site-related contaminants of concern (COCs).
Langan completed a forward-looking cumulative HHRA in order to estimate risk and hazards following a proposed remedial action. Post-remediation, a final HHRA was submitted to document that site cleanup objectives were met. To harmonize the ecological and human health risk assessments, the ecologically-based preliminary cleanup goals were evaluated to determine their health-protectiveness for human receptors. The site-specific assessment strategy resulted in findings that ecologically-driven remedial activities at the site sufficiently mitigated the risk associated with human exposure to COCs.

BCONE 2019 Northeast Sustainable Communities Workshop Recap
Langan Environmental Leaders Present and Celebrate Project Wins
The Brownfield Coalition of the Northeast (BCONE) hosted the Northeast Sustainable Communities Workshop (NSCW) 2019 at the New Jersey Institute of Technology in Newark, New Jersey, on June 4, 2019.
The conference emphasized the impact of sustainability on community revitalization. BCONE brought together experts to discuss redevelopment challenges, the use of technology as it relates to sustainability, and success stories.
