Proposition 65

Proposition 65 Lawyer in California 

Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, requires businesses to warn Californians about exposures to chemicals known to cause cancer, birth defects, or other reproductive harm.

If a business fails to provide these legally required warnings, it may be liable for civil penalties of up to $2,500 per violation, per day, retroactive for up to one year. This means even a single overlooked chemical in a product or on a website can result in hundreds of thousands of dollars in liability.

Litigating the Front Lines of Public Health​

Every business that sells products in California must comply with Proposition 65. This means clearly labeling products containing carcinogens or reproductive toxins, or ensuring those chemicals aren’t present at all.

Unfortunately, many companies don’t take this requirement seriously. That’s where Sentinel Law APC comes in. Sentinel Law APC pursues violations with purpose and precision.

We bring enforcement actions under Prop 65 on behalf of private citizens. Our process includes:

  • Scientific testing of suspect products
  • Submission of 60-Day Notices of Violation
  • Filing of civil complaints in the California Superior Court system
  • Negotiation of settlements, including reformulation, warning requirements, and monetary penalties
