Microplastics prevalent in Delaware River, according to new report by DRBC

Samples collected all contained plastic from Brandywine Creek, Cooper River, Neshaminy Creek

A new report released by the Delaware River Basin Commission found that microplastics are prevalent in the Delaware Watershed.

Grab sample concentrations ranged from 8.5-250.0 particles/cubic ft, with the highest concentrations occurring in Rancocas Creek. Mainstem Delaware River grab samples generally showed mid-high concentrations of microplastics.

Previously, a few microplastic studies have been conducted in the Delaware watershed but focused on the Delaware Bay and non-tidal Delaware, which left out the upper Delaware.

The research was conducted in the upper portion of the Delaware River estuary, or tidal reach, through monitoring and modeling.

“Our research, which revealed microplastics at all 15 sampling locations in three states, provides a vital first step in better understanding and managing this contaminant of emerging concern,” said Jacob Bransky, the DRBC’s Aquatic Biologist and study lead.

The complete results of this study can be viewed online.
