Cyclopure Expands PFAS Testing Initiative in Colorado for a Second Year

The CEO of Cyclopure, Frank Cassou, expressed his enthusiasm about the program, stating, "PFAS awareness is the first step to protecting families from the harmful effects of these chemicals in drinking water. We are excited to partner with CDPHE to ensure that private well users have access to reliable testing services."

The Cyclopure Water Test Kit Pro has been designed with convenience and affordability in mind. Funded by the National Institute of Environmental Health Sciences (NIEHS), this testing solution allows users to easily collect water samples without the need for complicated shipment processes. The kit employs a DEXSORB-loaded extraction disc, capturing PFAS concentrations that is later examined under precise laboratory conditions.

Advancements and Outreach



In 2025, the program aims to broaden its outreach efforts, focusing on areas including Gilpin, Grand, and Pueblo counties to further investigate well water safety. The aim of this expansive initiative is not just to test water but to systematically develop recommendations aimed at reducing PFAS exposure based on the collected data.

To date, Cyclopure has successfully tested over 25,000 water samples through its Water Test Kit Pro, validating its accuracy in various independent studies. This commitment to transparency and reliability underscores Cyclopure’s dedication to environmental health and safety.

Cyclopure's Mission



Cyclopure is headquartered in Evanston, Illinois, and is recognized for its innovative materials science and environmental engineering solutions. The company has developed DEXSORB®, a PFAS-selective adsorbent that is set to revolutionize how we deal with PFAS across multiple applications—ranging from environmental testing to residential filtering solutions and large-scale treatment systems.

In conclusion, as Cyclopure advances its testing program in Colorado, it serves as a perfect example of how public-private partnerships can create impactful solutions to environmental health issues. By prioritizing accessibility and community outreach, Cyclopure is paving the way for enhanced safety protocols and healthier water for all Colorado residents.
