Biomonitoring Program

DRBC's Biomonitoring Program samples sediment, rocks, algae, aquatic insects, and water chemistry to provide a complete overview of the diversity and health of the aquatic life community and overall water quality of the 200-mile non-tidal river.

Every two or three years, samples are collected at 25 river sites, targeting the richest habitat areas of riffles, runs, or island margins. The bulk of the biomonitoring program occurs during the months of August and September.

DRBC utilizes this information to implement biocriteria as part of Special Protection Waters regulations for the non-tidal portion of the Delaware River. Data assessed are also included in the Delaware River Water Quality Assessment Report that DRBC develops every other year for the U.S. EPA.
