    For years, harmful algal blooms (HABs) have posed a threat to drinking water across the country. And now, a tragic incident has illustrated that the problem can have an even more direct effect on our loved ones.

  2. EPA Determines Newark’s Lead Filters Not Working; City Distributes Bottled Water
    8/13/2019

    Late last week, the U.S. EPA sent a letter to officials in Newark, NJ, warning them that residents were exposed to dangerous levels of lead contamination in their drinking water and that the city’s efforts to mediate the crisis weren’t working.

  3. Harness The Power Of The Sun For Off-The-Grid Desalination
    8/8/2019

    Industrial and population growth continue to outpace the supply of freshwater resources in many regions of the world. The need for additional freshwater resources is driving the need for desalination. When combined with concerns regarding climate change and harmful impacts associated with fossil fuels, desalination powered by renewable energy should be considered as a necessary part of the solution.

  4. San Fran’s Water Recycling Project Could Save 30 Million Gallons Per Year
    8/6/2019

    San Francisco may be best known as a hotbed for the cultural changes of the 1960s and as a hub for some of today’s leading technologies. Now, it is bringing that cutting-edge reputation to bear in the water recycling space.

  5. Kentucky Utility Spares Consumers From Bourbon Blast

    Following a fire at a major bourbon distillery in Kentucky this month, water treatment workers stepped up to keep a bad situation from becoming even worse.

  6. Grading Pressure-Boosting Pump Efficiency — On A Curve
    7/18/2019

    Are your current pressure-boosting pumps the best design for your operating conditions? Are they maximizing value from your operating budget with peak efficiency? How can you know for sure, and what can you do if they are not? Here are some guidelines for evaluating performance efficiency in pressure-boosting applications and for choosing the best pump configurations for new or existing applications.

  7. Factoring Temperature Into Water Chemistry Reading Accuracy
    7/18/2019

    In water testing, readings that we believe to be reliable indicators are not always what they seem. Water that exhibits certain chemical or electrical characteristics at laboratory temperatures can provide entirely different readings in the field. Here is a quick review of what to look for in common water tests and why to consider automatic temperature compensation in the instruments used to collect them.

  8. Climate Change And Nutrients: Forewarned Is Forearmed
    7/17/2019

    Rising temperatures and precipitation combined with increasing nutrient runoff from human activity are elevating challenges in water treatment efforts. In some cases, that means increased threats to drinking water quality. In others, it means increasingly stringent nutrient discharge levels. Either way, taking the nutrient monitoring battle out to the field can help in waging a better fight at the treatment plant.

  9. Despite Potential Trump Veto, PFAS Amendment Passes House
    7/17/2019

    The U.S. House has approved an amendment to the annual defense spending bill that would target per- and polyfluoroalkyl substances (PFAS).

  10. Defending Against Saltwater Intrusion
    7/16/2019

    Are “ghost forests” a sign of things to come? Rising sea levels and superstorm tidal surges are already impacting coastal areas, with rising salinity levels affecting some drinking water sources. Coastal water utilities are not the only ones that have to worry about salinity, however, as high concentrations of winter storm road treatments, gas drilling, and mining can also generate elevated salinity levels in surface water sources.
