Chemists at University of California, Los Angeles, and Northwestern University discovered a new way to destroy "forever chemicals," using a common ingredient in soap and an organic solvent, according to a study published in the journal Science on Thursday.

Why it matters: The extremely durable and toxic chemicals have been in drinking water systems around the U.S. and are linked to adverse health effects. The new method is a relatively cheap and mild way to break them down.

Per- and polyfluoroalkyl substances (PFAS) — dubbed "forever chemicals" for their durability — are a family of nearly 5,000 types of chemicals that largely resist degradation by repelling oil and water and withstanding high temperatures.

• They have been used in several nonstick, water-repellent and fire-resistant industrial and consumer products for decades, including cookware, some food packaging and fire fighting materials.
• Because they resist degradation, PFAS can accumulate in people, livestock, fish and wildlife if they enter the environment through production or waste streams.
