Thus far, there have been a lack of official federal or state requirements concerning PFAS, which has led to inaction for many water treatment plants (WTPs). Along with the lack of federal maximum contaminant levels (MCLs) to target, many WTPs simply don't know where to begin. There are a range of solutions to choose from, and the ideal solution can depend on factors specific to the plant, such as average water temperature, pressure, flow rates, and other contaminants present in the water.
But choosing a PFAS solution does not have to be an insurmountable task. It can be tempting to sit and wait for regulators to set enforceable MCLs, but the health and well-being of the community should be the top priority. Luckily, there is a cost-effective solution to this dynamic problem. Smaller WTPs can home in on the most viable technologies by keeping a few key guidelines in mind.
