Microplastic Contamination Found in Common Source of Groundwater, Researchers Report

Microplastics contaminate the world's surface waters, yet scientists have only just begun to explore their presence in groundwater systems. A new study is the first to report microplastics in fractured limestone aquifers – a groundwater source that accounts for 25 percent of the global drinking water supply.

Microplastics contaminate the world's surface waters, yet scientists have only just begun to explore their presence in groundwater systems. A new study is the first to report microplastics in fractured limestone aquifers – a groundwater source that accounts for 25 percent of the global drinking water supply.

The study identified microplastic fibers, along with a variety of medicines and household contaminants, in two aquifer systems in Illinois. The findings are published in the journal Groundwater.

“Plastic in the environment breaks down into microscopic particles that can end up in the guts and gills of marine life, exposing the animals to chemicals in the plastic,” said John Scott, a researcher at the Illinois Sustainable Technology Center and study co-author. “As the plastics break down, they act like sponges that soak up contaminants and microbes and can ultimately work their way into our food supply.”
