6 million Americans are drinking contaminated water linked to cancer

More than 6 million Americans are drinking water polluted with highly fluorinated chemicals.

The most-studied chemicals in the class are linked to kidney and testicular cancer, thyroid disease, decreased sperm quality, high cholesterol, decreased immune function in children, and other serious health problems.

Highly fluorinated chemicals are found in firefighting foam used by military and domestic airports, furniture, carpets, outdoor gear, clothing, cosmetics, cookware and food packaging. The chemicals make their way from manufacturing facilities, consumer products and firefighting activities into the air, water, and food, and then into humans.
