New reportable chemicals added in 2021!

  • 175 Per- and Poly-fluoroalkyl Substances, collectively known as PFAS, were added to the Federal List of Lists in 2021 and are now subject to reporting under the Groundwater Protection Program as hazardous materials.
  • PFAS are common in a lot of modern products and processes. In particular, chrome plating, electronics, and certain textile and paper manufacturers are likely to have PFAS in their operations.
  • Please check in with your suppliers for updated Safety Data Sheets to see if this may apply to your facility. And as always, you can contact the Columbia Corridor Association or your local city water provider with any questions.
