Toxic levels of hydrogen sulfide detected near East Bay wastewater treatment plant
Public health officials in Contra Costa warned people who live near the Crockett wastewater treatment plant that harmful levels of hydrogen sulfide were emanating from the facility on Friday, causing putrid smell to waft through the air, and potentially causing headaches or nausea. Residents recently began complaining about rotten egg odors that appear linked to an “ongoing operational issue” at the plant on 1801 Dowrelio Road, county health staff said in a notice Friday afternoon. It said that Bay Area Air Quality Management District monitors had found dangerous levels of hydrogen sulfide in the surrounding air.
