REPORT SPILLS, ILLEGAL DUMPING AND BACKUPS

Accidental spills or illegal dumping of industrial or household pollutants near storm drains can harm sensitive creek ecosystems and storm drain blockages can lead to street flooding. Sewer blockages can result in expensive sewer line repairs and overflows of wastewater and pollutants into neighborhoods and creeks. 

Report spills, dumping or backups in your community.

AMALGAM MANAGEMENT REQUIREMENTS FOR DENTAL PRACTICES

San Francisco Bay is impaired due to high levels of mercury in fish, water and Bay sediment. To reduce mercury loadings to the Bay, dental practices that remove or place amalgam fillings must use approved amalgam best management practices and install an amalgam separator. These requirements have reduced the amount of mercury entering the Bay from the RWQCP wastewater effluent by more than 50%. Compliant dental offices:

  • Follow all amalgam management requirements.
  • Review the Amalgam Best Management Practices provided by the California Dental Association.
  • Train staff in the proper handling and disposal of amalgam materials and fixer-containing solutions; training records must be available for inspection.
  • Install an approved amalgam separator that will remove up to 95% of the amalgam particles
  • Store amalgam waste in accordance with recycler or hauler instructions
  • Do not rinse chairside traps, vacuum screens, or amalgam separator equipment in a sink or other sanitary sewer connection.
  • Do not use bleach or other chlorine-containing disinfectants to disinfect the vacuum line system.
  • Do not use bulk liquid mercury; only precapsulated dental amalgam is permitted.
