Third party product certification for drinking water health effects.

Third-party certification to drinking water product consensus standards is how products for potable water systems are deemed suitable for public health and safety in North America. Drinking water product consensus standards are a type of standard developed through a process that includes participation from expert volunteers and requires general agreement from all stakeholders. Certification to drinking water product consensus standards is required plumbing codes and state or local regulations in most of the United States and Canada, making third-party certification essential for products intended for sale and installation in North America.
