A.U.G. Signals: Near-real-time readings help drinking water plants keep THMs in check
Across North America, drinking water treatment plants have to keep trihalomethanes (THMs) — a potential carcinogen — below strict limits. However, if they don’t have sophisticated gas chromatography equipment and trained specialists on site, plants must rely on commercial labs to test their samples. That means waiting up to a week to get results, which can
