The Biden administration has set the first ever national standard to limit forever chemicals in our drinking water.

These chemicals are officially known as PFAS, spelled out PFAS.

A government study found they're present in nearly half of the United States drinking water.

These forever chemicals can stick around in our environment and in our bodies.

They are linked to a variety of health problems that include cancer, thyroid disease, reproductive problems, and heart and liver damage.

The CDC says these chemicals can be found in the blood of nearly 97 percent of Americans.

This regulation is designed to reduce exposure to these chemicals for about 100 million people across the United States.

The plan targets five specific types of chemicals and sets strict limits for them.

Water treatment facilities have three years to start testing, and another two years to implement technology to filter out these chemicals.

The federal government has set aside a billion dollars to do it.
