Drinking water serving 7.5 million Californians has been contaminated with toxic PFAS, new report says:
Chemical contaminants were detected in water sources serving more than 7 million Californians, according to a new report by the Environmental Working Group.
The nonprofit, which describes itself as “dedicated to protecting human health and the environment,” found that water sources for 74 community water systems — serving 7.5 million people in California — have been contaminated with PFAS chemicals.
The US Environmental Protection Agency says studies have shown high concentrations of PFOA and PFOS, two of the potentially thousands of types of PFAS chemicals, can cause increased cholesterol levels in humans, along with immune system issues, thyroid problems and even cancer.
EWG’s findings don’t necessarily reflect what’s coming out of consumers’ taps right now. The nonprofit used data from water samples — meaning that it’s more a reflection of the extent of the contamination, it said in a statement.
This is why all homes need a whole house water filtration system from Superior Water.
