Contra Costa Health has been responding this week to complaints about a strong odor coming from the West Contra Costa Sanitary Landfill Organic Material Processing Facility in Richmond, a solid waste management facility that processes organic waste into compost.
Air monitoring was conducted on March 26th for chemicals that would be associated with decomposing odorous organic matter. Our air monitoring onsite and in the community (the Hilltop area, Tara Hills and along the Richmond Parkway) did not find any levels that would constitute a health concern.
Our Environmental Health and Hazardous Materials inspectors will continue to work with the Bay Area Air District to track this incident, conduct additional air monitoring as necessary and provide updates.
