EPA is providing information on NSF-60 certified C02 suppliers 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.
NSF-60 Certified Suppliers
The map on the next page provides information on utilities that utilize C02 and facilities that supply NSF-60 certified C02. Many of them operate
in multiple states. C02 producers often sell their C02 to a supplier that can process (e.g., purify, compress) and deliver the C02 to water utilities
and other customers. The map shows the location of C02 suppliers relative to water utilities as proximity to a C02 supply can be a critical
constraint given that long distance transport of high purity C02 can be prohibitive in terms of expense and logistics. Clicking on a state
abbreviation will bring you to the full list of suppliers by state, found in Table 1.
The suppliers listed in the map and corresponding table below were identified through the NSF website. To search for NSF-60 certified suppliers
and other certified drinking water chemicals, visit the Search for NSF-60 Certified Drinking Water Treatment Chemicals page.
