THE CONTINUOUS ON-LINE MONITORING OF ENVIRONMENTAL POLLUTANTS IN STORMWATER
A monitoring system is described which provides continuous measurements of selected pollutants in stormwater. The system, which has been installed at both the outfall to a storm-water pipe system and in a gullypot, is sensitive to changes in pH, conductivity, dissolved oxygen concentration, temperature and redox potential. At the stormwater outfall monitoring station rapid changes of conductivity and turbidity are associated with the incoming rainfall, while the pH change is less sensitive due to road surface and in-pipe buffering. Temperature changes provide an indication of in-pipe water reservoir flushing. “Complete abstract not presented.”
