For a low-cost method of measuring disinfection efficiency and contamination levels, Cole-Parmer presents the new GreenLight® Environmental Bacterial Count Systems. The systems are ideal for monitoring wastewater discharge for disinfection limits in NPDES permits, drinking water plant disinfection, and bacteria in water at beaches. The systems measure oxygen consumption to determine the level of live aerobic bacteria.
