The intention of Proposition 65 is to protect the public and its drinking water resources and to inform the public about potential exposures to chemicals. 

Proposition 65 (Prop 65) (previously known as the Safe Drinking Water and Toxic Enforcement Act) protects California citizens and the State’s drinking water sources from chemicals known to cause cancer, birth defects, or other reproductive harm, and informs citizens about exposures to such chemicals. Prop 65 requires the Governor to publish and update a "List of Chemicals Known to the State to Cause Cancer or Reproductive Toxicity." 

  • Twelve months after a chemical is listed, businesses are prohibited from knowingly and intentionally exposing individuals to that chemical without first giving a clear and reasonable warning. 
  • Twenty months after a chemical is listed, businesses are prohibited from knowingly discharging listed chemicals into sources of drinking water. 

Prop 65 requires any Designated Government Employees (DGE) who obtains information in the course of their official duties regarding an illegal or threatened illegal discharge of hazardous waste to report this within 72 hours to the Board of Supervisors and the Health Officer. The Orange County Health Care Agency is responsible for providing this information to the local news media pursuant to California Health and Safety Code section 25180.7(d).
