Emerging Chemical: PFAS Explained

Some of the emerging chemicals that we are keeping a close eye on are Per-/Polyfluoroalkyl substances (also known as PFAS). PFAS are a group of man-made chemicals used in various industries worldwide for more than 70 years. They are commonly found in products like non-stick cookware, waterproof clothing, food packaging, and even firefighting foams. PFAS are highly resistant to heat, water, and oil, which is why they have been popular in the manufacturing of products that need these properties. Because of these attributes, however, PFAS don’t break down easily in the environment. We monitor PFAS levels as they relate to our water sources to protect public health.

We care about the safety and quality of your water and making sure you are fully informed about the latest in water quality and public health updates. Working alongside state and federal agencies as well as water quality experts, LACWD has prepared the following resources in regards to PFAS:
