About Our Program

Each summer, a team of RHA staff members and volunteers collect samples of benthic macro- invertebrates, small critters whose presence indicate a stream’s health, at over fifty sites on streams and rivers in Hunterdon, Morris and Somerset Counties. Through our stream monitoring program, we gather valuable, usable data about surface water quality and the overall health of our watersheds.
