  3. Calling On Utilities To Combat Legionella 5/5/2022

    The risk level linked to delivered drinking water from municipal utilities is very small, even if some high-profile examples of failure (see Flint, MI) have degraded public confidence to a degree. Our treatment professionals usually hit their targets, so the onus then shifts to the research and guidance that determines the safe level of various constituents through U.S. EPA protocols. But there is one contaminant that rulemaking hasn’t quite caught up to and which is downright deadly — Legionella pneumophila.

  8. Restoring A Unique Area In Northwest Indiana 4/13/2022

    Although discharges of toxic substances into the Great Lakes have been reduced over the last 50 years, high concentrations of contaminated sediment remain in the bottom of some rivers and harbors. These contaminants pose potential health risks to people and wildlife, and states have issued fish advisories in many Great Lakes locations.

  9. Multidistrict Litigation Suit For PFAS Contamination Gains Momentum 4/13/2022

    Water system providers across the U.S. have joined a multidistrict litigation (MDL) suit claiming that their water supplies are contaminated with per- and poly-fluoroalkyl substances (PFAS) from aqueous film-forming foam (AFFF). These chemicals have been used for decades to extinguish chemical or petroleum fires at military bases, airports, and industrial facilities.
