Microplastics, plastics smaller than 5mm, are an emerging environmental issue that scientists are surveying to understand how they impact waters and wildlife world-wide. Often these plastics come from our waste water treatment plants, which aren’t equipped to filter such small plastics. Microplastics also form when larger plastics degrade. Since 2016, HRP has partnered with Brooklyn College to research the concentration of microplastics in Park waters and support regional efforts to understand this emerging threat.
In 2017, there was an estimated 99,692 pieces/km2 average microplastic concentration within the 400 acres of the Park’s waters
