Proposition 65 is a California citizens initiative that was enacted as “The Safe Drinking Water and Toxic Enforcement Act of 1986.” Proposition 65 requires the State to publish a list of chemicals known to the state of California to cause cancer or birth defects or other reproductive harm. Businesses are then required to notify Californians about these chemicals if they are present in the products they purchase, in their homes or workplaces, or that are released into the environment.
