Two of the most common water quality questions we hear right now are about PFAS and microplastics. Homeowners are searching, reading, and worrying, and understandably so. But there’s a lot of confusion about what these contaminants actually are, how they differ, and whether you need to worry about one, the other, or both. This article gives you straight answers based on the latest science.<\/p>\n

What Are PFAS and What Are Microplastics \u2014 Are They the Same Thing?<\/h2>\n

No. They are fundamentally different types of contaminants, though they are increasingly found together and interact with each other in ways that researchers are only beginning to fully understand.<\/p>\n

PFAS (per- and polyfluoroalkyl substances)<\/strong> are man-made chemicals<\/em> \u2014 a group of more than 15,000 synthetic compounds used in manufacturing since the 1940s. They are found in nonstick cookware, food packaging, firefighting foam, waterproof clothing, and hundreds of industrial applications. PFAS are called “forever chemicals” because the carbon-fluorine bond at their core is one of the strongest in chemistry. They do not break down in the environment or in the human body. They are invisible, dissolved in water, and have no taste or smell.<\/p>\n

Microplastics<\/strong> are physical particles<\/em> \u2014 tiny pieces of plastic material less than 5 millimeters in size, broken down from larger plastic waste or shed from synthetic textiles, tires, and consumer products. Unlike PFAS, microplastics are solid particles you could theoretically see under a microscope. They are not dissolved in water \u2014 they are suspended in it.<\/p>\n

\"Microplastics<\/p>\n

The simplest way to remember the difference: PFAS are invisible chemicals dissolved in water. Microplastics are tiny physical particles floating in it. Both are widespread, both are concerning, and \u2014 critically \u2014 both are increasingly found together.<\/p>\n

How Do PFAS and Microplastics Get Into Drinking Water?<\/h2>\n

Both contaminants reach drinking water through multiple pathways. Many of those pathways overlap, which is part of why they so often appear together.<\/p>\n
