What is PFAS?

PFAS, also known as “forever chemicals” refers to a class of thousands of synthetic man-made substances that have been used in industry and consumer products worldwide since the 1940s. Due to their unique and extremely strong chemical bond, these compounds are resistant to heat, grease, water and oil. They have been used in non-stick cookware, food packaging, dental floss, pizza boxes, household cleaners, water-repellent clothing, cosmetics and firefighting foams.

As the Coronavirus continues to propagate through the country and into our communities, many people are leaning on self-proclaimed "experts" to determine the best course of action to protect themselves. The product which is most sought after, other than toilet paper and hand sanitizer, is the "dust mask" or "facemask." This term is used interchangeably for a paper-like mask that covers your face. It is believed that a dust mask protects you from dust and other airborne contaminants. This term makes its way into the vernacular of seasoned health and safety professionals, as well as highly educated medical professionals. The problem is when it is used so interchangeably, it spreads misinformation that may confuse the public and cause a dangerous and false sense of security. People hear terms like N95, N100, P99, surgical mask and on. What do those terms mean? How do you know if it is actually protecting you?

  • It holds an NPDES stormwater permit; or
  • It’s not required to have a stormwater permit.

This new requirement could delay or even prohibit the issuance or renewal of a business license (Link 1). Knowing the facts, however, can keep you covered.
