  • Final effluent monitors protect wastewater treatment efficiency

    Southern Water operates 370 wastewater treatment plants (WWTP), many of which are unmanned for most of the time and most have numeric environmental permits, so a network of online monitors has been established to improve treatment and protect discharge compliance. This has involved the installation of final effluent monitors at over 300 sites in a programme that has lasted for more than ten ...


  • Effect of sodium thiosulfate on toxicity of copper, cyanide, and malathion to vibrio fischeri using the toxControl online toxicity monitor

    The U.S. Environmental Protection Agency is conducting research to develop online toxicity monitors (OTMs) for use in water quality early warning systems. A major element of this effort is determining the applicability of different OTMs and their responses to various toxic substances. One aspect of this research is the potential application of OTMs in drinking water distribution early warning ...

  • Homeland Security for Drinking Water Supplies

    As it has done with other jurisdictions, Congress has recently passed legislation aimed at protecting our nation's drinking water resources. Historically, water supply protection has been a high priority, including reservoir protection, continuous monitoring, and secure and redundant facilities to ensure an uninterrupted supply of drinking water. The Clean Water Act (1972), requires pollution ...
