One study, published in the journal Environmental Science & Technology Letters on Oct. 14, found that toxic chemicals may be far more prevalent in drinking water than previously thought. The researchers estimated that more than 200 million Americans could have per- and poly-fluoroalkyl substances (PFAS) in their drinking water at a concentration of 1 part per trillion (ppt) or higher. This means that nearly 60 percent of Americans may have drinking water contaminated with PFAS at higher than 1 ppt. According to the Environmental Working Group (EWG), a safe level for PFAS in drinking water is no more than 1 ppt. “We know drinking water is a major source of exposure of these toxic chemicals,” Olga Naidenko, PhD, vice president for science investigations at the EWG and a co-author for the study, said in a statement. “This new paper shows that PFAS pollution is affecting even more Americans than we previously estimated. PFAS are likely detectable in all major water supplies in the U.S., almost certainly in all that use surface water.” PFAS are known as “forever chemicals” because they are some of the most persistent toxins known to man and can contaminate everything from drinking water to food, and even personal care products and cosmetics. According to the EWG, they also “build up in our bodies and never break down in the environment.” To find out just how PFAS can hurt your health, keep reading.

According to the Agency for Toxic Substances and Disease Registry (ATSDR), exposure to high levels of PFAS can impact the immune system by reducing antibody responses to vaccines. This can also “reduce infectious disease resistance,” which is especially concerning during the COVID pandemic.

According to the researchers, this includes, but is not limited to, breast, kidney, prostate, liver, and testicular cancers.

This notion comes from the research done in a major 2008 study that found a specific PFA, perfluorooctanoic acid (PFOA), was linked to higher levels of cholesterol in 69,000 West Virginians and Ohioans whose drinking water was contaminated by a DuPont manufacturing plant. According to the EWG, this toxin is used by DuPont to make Teflon, food wrappers, and other consumer products.

A 2018 study published in PLOS Medicine found that people with higher levels of PFAS in their bodies regained more weight after trying to diet than those with lower levels of the toxin. Qi Sun, a professor at the Harvard Chan School and senior author for this study, said in a statement that this research concluded PFAS “might interfere with human body weight regulation and thus contribute to the obesity epidemic.” And for more up-to-date information, sign up for our daily newsletter.
