The engineering profession has developed treatment technologies that address the myriad of different chemicals encountered in leachate. In recent years, however, potential health concerns form a newly appreciated suite of trace chemicals has emerged on the national stage: per- and poly-fluoroalkyl substances (PFAS). Thousands of PFAS chemicals have reportedly been developed and used in a multitude of industrial and commercial products, including firefighting foams, water-repelling agents in our clothes and shoes, and in food product packaging. Because PFAS chemicals are designed for purposes such as repelling water and stains, and to keep materials from sticking to one another, they tend to be mobile and persistent when they enter the environment and thus are not easily removed with existing treatment technologies.
