Susquehanna River Basin's Early Warning System

The Commission set up the Early Warning System (EWS) to help protect and manage public water supply operations with sources in the Basin’s major rivers. The EWS provides a framework to share real-time water quality information among public water suppliers, state/local agencies, and the emergency response community for the benefit of approximately 850,000 public water customers. EWS sensors constantly monitor for basic water quality indicator parameters that can provide crucial information in the event contaminants are released into a river as well as help optimize water treatment efficiency on a short-term or seasonal basis to address conditions brought on by storms, excessive plant/plankton growth, or drought. Turbidity, pH, and temperature are monitored at all stations; whereas some stations also are equipped to measure total organic carbon substances, specific conductivity, and/or dissolved oxygen.
