Rafat is a Senior Consultant based in California with more than 35 years of experience focused on vapor intrusion and remediation of redevelopment properties, including manufacturing, commercial, agricultural, dry-cleaning, and military sites. Rafat worked with Robbie Ettinger to update the Johnson and Ettinger model that calculates vapor migration to indoor air.

Rula is a Senior Principal based in California with more than 25 years of experience focused on addressing the cross-media fate and transport of contaminants and the remediation of complex soil and groundwater sites impacted by nonaqueous-phase liquids and emerging contaminants like PFAS. Rula is Geosyntec’s Vice President of Practice Development.

Syed is a Senior Principal Environmental Engineer based in California with more than 30 years of experience focused on developing engineering solutions and regulatory compliance strategies for environmentally impaired sites impacted by chlorinated solvents, heavy metals, hydrocarbons, and petroleum products in soil, groundwater, soil vapor, and indoor air.

Elham is a Project Engineer based in California with a focus on modeling approaches to address vapor intrusion pathways. She has extensive experience in environmental engineering, landfill redevelopment, California Title 27 compliance, environmental monitoring, and the design and implementation of vapor intrusion mitigation systems.

CALRC brings together environmental, redevelopment, planning, and community development professionals to explore innovative approaches to brownfields redevelopment, land recycling, and sustainable community revitalization. The conference provides opportunities for education, collaboration, and networking while highlighting strategies that transform underutilized properties into productive community assets.
