A Guide to PFAs in Central City Water

As a resident of Central City, IA, you may have heard about the high levels of polyfluoroalkyl substances (PFA) in the public water supply. While this information is good to know, you may not know what PFAs are or whether you should be concerned that they are present in the municipal water supply. Fortunately, with the right water filtration system, you can remove these chemicals from your water and ensure everyone stays healthy. Here is more information about them to help you prepare.



What Are PFAs?

PFAs are a group of synthetic chemicals that do not break down easily and are difficult to remove from water. They are commonly used in industrial and commercial settings for their nonstick and water-resistant properties, particularly in consumer products, such as cookware, clothing, and food packaging. When they leak into the environment, including public water supplies, they can remain for a long time. The most common source of drinking water contamination is aqueous fire-fighting foams (AFFF). 

When consumed in high concentrations, PFAs can persist in the body for years and negatively affect your health. Some research suggests that these chemicals might cause developmental defects in children. They may also reduce fertility, damage the immune system, affect natural hormone levels, and increase the risk of certain cancers.

What Is the City Doing About Them?

Testing by the Iowa Department of Natural Resources (IDNR) in Central City public wells showed PFA levels below the Environmental Protection Agency’s health advisory limit of 70 parts per trillion. Still, the IDNR is requiring the city to continuously test public water and monitor PFA levels to ensure they don't rise to unsafe amounts. Once testing begins in the second quarter of 2022, the city must keep the public updated as more information becomes available.

How Can You Ensure the Supply Is Safe?

Although PFAs are difficult to remove, installing a specialized water filtration system can help. According to the EPA, granulated activated carbon (GAC) filters are efficient tools for removing these compounds. Under ideal conditions, a GAC filter can even be 100% effective. This water filtration system works by absorbing synthetic chemicals directly. 

Another type of treatment, known as reverse osmosis (RO), is also an effective method of removal. However, RO systems retain about 20% of the water treated, leaving concentrated and contaminated wastewater. While this wastewater can be challenging for cities to dispose of, the amount is smaller and more manageable in residential settings.
