PFAS has been widely used since the 1940s and can be found in clothing, furniture, carpets, food packaging, cosmetics and more. PFAS are also found in firefighting foams and other industrial processes.

Most people are exposed to PFAS through the consumer products they use, however these same channels direct PFAS into the water supply. Thus, our water supply has become another source for PFAS exposure.

Many factors can influence individual impacts of PFAS including health history and lifestyle. According to the CDPHE, there is strong evidence that PFOS and PFOA increase cholesterol, impact the immune system, decrease infant birth weight and cause changes in liver function. There is moderate evidence that PFAS are associated with preeclampsia and high blood pressure during pregnancy and has effects on thyroid hormones. There is also evidence that PFOA increases the risk of kidney and testicular cancer.

Children ages 0-5 years, and people who are pregnant, planning to become pregnant, or breastfeeding are more susceptible to health impacts from these chemicals. Other vulnerable populations include people who live in highly contaminated communities and people who have occupational exposure. 

Centennial Water is closely monitoring PFAS and EPA recommendations. We have been monitoring and testing for PFAS since 2019, and we have detected PFAS in our untreated water. Centennial Water’s latest test results comply  with the EPA’s new standards. We have proactively been investigating ways to refine our treatment process for PFAS removal and are doing everything we can to minimize its presence using current treatment techniques.
