Food Grade CO2 Suppliers and Producers

EPA is providing information, in the below document, on food grade CO2 suppliers and producers in the event that water utilities need to identify alternative companies, pursuant to Section 1442(a)(2) of the Safe Drinking Water Act. EPA does not endorse companies or specific products, absent any statutory authority to do so, and recommends that utilities contact individual companies for additional information.

Note: If your company is a supplier or producers of food grade CO2 to water utilities, please contact EPA at wisniewski.lauren@epa.gov to be included on this list or for additional information.
