Waterwise Wednesday: Plastic Rain in the Rocky Mountains

Over 90% of Rocky Mountain rainwater samples gathered for a United States Geological Survey contained microplastics, plastics less 5 mm or less. While urban samples contained more plastic, samples from remote sites indicate microplastics may be more pervasive.

Some microplastics are released as tiny particles like fibers from synthetic clothing or car tire fragments. Others fibers come from the breakdown of larger plastic items like bags and bottles. The particles migrate and have been found in the remotest parts and people on the planet.
