Water Quality
Stream Gauge
The GSWA works to preserve our local streams and protect water quality. Rainwater flows into the watershed from five streams — Loantaka Brook, Great Brook, Primrose Brook, Black Brook, and the Upper Passaic — collects, and exits as the mighty Passaic River, which rises in the Great Swamp watershed. Over a million people get their drinking water from the Passaic River.
The monitoring work done by our “stream teams” of volunteers formed the basis for the first-ever water quality standards for the watershed. These standards help protect streams from future harmful impacts and prioritize the more degraded streams for restoration efforts. GSWA successfully established the “Adopt-A-Stream” program with funding from local corporations. The goal of this program is to reduce pollution levels in all five streams in the watershed utilizing public and corporate volunteers. The initial focus is on restoration of Loantaka Brook, the most polluted of the streams. We have identified the sources of contamination and are addressing the most immediate problems.
