    Due to microbiological activity in the process, or to a lesser extent due to the reduction in nitrate levels in the raw water, nitrogen compounds may give rise to increased nitrite concentrations. By Endress + Hauser, Inc.

  8. Water Supplier Ensures DBP Compliance With UV254 Organic Monitoring
    3/18/2009
    Mohawk Valley Water Authority (MVWA) is a progressive supplier of potable water. With source water from the Adirondack Mountains, MVWA works to improve on nature and provide superior water quality, always striving to meet or exceed drinking water standards. Like many other surface water sources, MVWA’s water supply is rich with natural organic matter (NOM). Unfortunately, growing research has demonstrated that NOM in water when combined with chlorine leads to the formation of potentially harmful disinfection by-products. By Jodi Glover, Real Tech Inc.
