Understanding microplastics in water: Fact vs. fiction

Arcadis Director of Applied Research Brent Alspach discusses the ongoing fact-finding mission in the water industry regarding microplastics, urging careful consideration of their potential risks and the need for more scientific understanding.

While microplastics are detected nearly everywhere, including the human body, Arcadis Vice President and Director of Applied Research Brent Alspach cautions against conflating their occurrence with proven risk. He explains that the water industry is currently on a "major fact-finding mission" regarding microplastics due to significant knowledge gaps and that the current science does not yet fully support the conclusion that microplastics are dangerous simply because they are present.

Until more scientific understanding emerges regarding their exact dangers and mechanisms, he advises individuals concerned about microplastics to minimize their exposure to plastics generally. The Water Research Foundation offers communications resources (Project 5155) published in the previous year to help communicate information about microplastics to the public.
