And due to their high solubility, they do not degrade and can lead to widespread contamination. Michael Kozak, business unit president - environmental & infrastructure at Minerals Technologies Inc., explains: “These compounds are notorious for their persistence and ability to spread quickly through groundwater, increasing the risk of exposure and potential harm to human health. The ubiquity of PFAS is alarming due to their proven adverse effects on human health, leading to significant regulatory attention worldwide, including stringent limits on PFAS levels in drinking water.”

Understanding water quality is not just a task for regulators; it is something we all need to be aware of. Melissa Aquino, senior VP of the water quality segment at Veralto, offers practical advice: “I recommend that individuals take the time to read and understand their local water quality reports, which are sent out by municipalities. These reports detail the contaminants tested for and their levels in the water supply. It is important for everyone, especially families, to be informed about what is in their water and understand the measures being taken to ensure its safety. At home, I engage my children in this learning process, showing them how water testing works using simple kits that even children can use.”

Aquino also touches on the complexities of regulating water contam- inants: “The intention behind setting such low regulatory limits for contaminants like PFAS is to exert pressure on the system to eliminate harmful chemicals. However, another challenge is the practicality of dealing with these contaminants once captured—whether in filters or granulated activated carbon, they still need disposal.”

Water management is more important than ever before. As the impact and awareness of contamination grows, so will the need to take action. We can take action ourselves with increased awareness of what may be in our water.
