The NSF-60 Certified CO2 Suppliers and Food Grade CO2 Suppliers and Producers maps provide information on food grade and NSF-60 certified CO2 suppliers and producers in the event that water utilities need to identify alternative companies.
You can also use the NSF Website to search for NSF-60 certified suppliers and producers for CO2, as well as other certified treatment chemicals. To search for NSF-60 certified suppliers, visit the Search for NSF-60 Certified Drinking Water Treatment Chemicals page.
Public water systems (PWSs) and publicly owned treatment works (POTWs) may experience a shortage or other serious supply chain issue for water treatment chemicals and other critical supplies.
Before contacting EPA for direct technical assistance, systems should first consider the following steps in an attempt to secure the required resource:
- Communicate with your current supplier to understand the cause and expected duration of the potential shortage.
- Identify potential alternate suppliers in your region that meet your supply requirements. See guidance under “Find Suppliers Near You.”
- Consult your state primacy agency to identify options during emergency situations to address the shortage while maintaining compliance with drinking water standards or discharge permits. This might include temporary approval to use an alternate chemical or a different grade of the same chemical.
- Utilize mutual aid and assistance networks such as the Water and Wastewater Agency Response Network (WARN) that may provide additional relief.
If you are unable to secure the necessary resources after taking the actions listed above, contact WSD-Outreach@epa.gov to request technical assistance to help resolve the issue.
EPA also tracks reports of shortages in order to identify systemic supply chain issues that could broadly impact the water sector. If you experience a shortage that you believe could be due to a systemic supply chain issue, you can report it to WSD-Outreach@epa.gov.
SDWA Section 1441 authorizes the Department of Commerce (DOC) to issue an order to a vendor to provide the necessary amount of a water treatment chemical or substance to a PWS or POTW when the chemical or substance is not reasonably available.

The DPA authorizes the President to require the preferential acceptance and performance of contracts or orders (other than contracts of employment) that support certain approved national defense and energy programs, and to allocate materials, services, and facilities in such a manner as to promote the national defense—this includes contracts or orders to support public health through clean drinking water or wastewater services.
