Underwriters Laboratories (UL) has announced improved testing methods for detecting and analysing emerging contaminants in drinking water.
The organisation has combined existing proprietary testing methods for identifying emerging contaminants in water.
By using highly specific and sensitive instrumentation practices, UL has developed two new methods that provide cost-effective analytical services for contaminants such as PhACs in the 160,000 water supplies in the US.
UL combined its existing methods (L200, L211, L220 and L221) to develop UL test method L222 used for the analysis of endocrine-disrupting chemicals (EDCs) and pharmaceutical and personal care products (PPCPs).
This method focuses on detecting and analysing nearly 30 most frequently studied and detected contaminants of emerging concern, including acetaminophen, bisphenol A, caffeine, DEET, estrone, nicotine, nonylphenol, triclosan and others.
UL also streamlined the analysis of selected semi-volatile organic compounds including sterols, phosphate flame retardants, fragrances, polyaromatic hydrocarbons (PAHs), phenols and pesticides to create UL method S190.
Both the L222 and S190 testing methods are used to analyse contaminants of emerging concern found in treated wastewater, surface water, groundwater and municipal drinking water.
