Drinking Water Treatment Insights

  1. Getting Serious About Lead Service Line Replacement
    10/29/2018

    It has been 32 years since the amended Safe Drinking Water Act (SDWA) banned the installation of lead pipes in water systems nationwide. Unfortunately, that decision has not yet translated into action for every lead service line (LSL) installed before that point. Fortunately, someone has done a lot of legwork toward getting a handle on that process. Here is a preview of the help they have to offer.

  2. Identifying The Best Lead Sampling Techniques To Protect Public Health
    10/23/2018

    If lead is found in drinking water, it is important to identify where it is coming from within the water system — that means taking samples at every stage, from the distribution system all the way to the plumbing system inside the home, also known as premise plumbing.

  3. How To Provide Effective Disinfection With No Hazardous Chemicals
    10/19/2018

    Reliable and effective disinfection is a cornerstone of water and wastewater treatment, needed to protect public health. Most drinking water utilities are required to maintain a minimum disinfectant residual in the distribution system. This ensures adequate chemical was applied and remains in the system to kill pathogens. The most commonly used disinfectants — chlorine gas and bulk sodium hypochlorite — require operators to regularly handle these hazardous chemicals.

  4. Coping With Mixed-Source Water Quality And Corrosion Challenges
    10/12/2018

    When it becomes necessary to expand or blend water supply sources, variety is not necessarily the spice of life. Whether new water sources are surface water or groundwater, fresh, brackish, seawater, or water recovered from aquifer storage, they can ultimately impact water treatment plant (WTP) operations and finished water quality — including compliance with the U.S. EPA Lead and Copper Rule.

  5. How To Mitigate Biofouling In Your Industrial Process Using 2nd Generation ATP
    10/9/2018

    Microorganisms can wreak havoc in industrial processes in a number of ways – from slime formation that causes paper breaks and excessive downtime in papermaking facilities, to costly recalls of spoiled final product. Consequently, an effective microbiological control program, which includes accurate and reliable monitoring, is critical for maintaining an efficient process and final product quality.

  6. What’s In Your Water? An Updated Analysis
    9/24/2018

    NRDC’s new analysis of the most recent EPA data finds that nearly 30 million people in the United States drank water from community water systems that violated the EPA’s Lead and Copper Rule between January 2015 and March 2018.

  7. USGS Shares Wellspring Of Insight On Groundwater Trends
    9/24/2018

    If your customer base is among the 140 million people who depend upon groundwater for drinking water, irrigation, or agriculture, it is important to know whether you can expect the quality of your source water today to be the same tomorrow. Fortunately, a recent update to the first-of-its-kind assessment of trends in groundwater supply has been announced by the U.S. Geological Survey (USGS) to help you identify emerging problems. The results are detailed in an informative and easy-to-use interactive map.

  8. How To Boost Water System Efficiency With Smart Output Technology
    9/21/2018

    Water utilities are installing automated meter reading (AMR) and advanced metering infrastructure (AMI) systems more frequently. These systems often help utilities improve customer relations and provide valuable real-time data to improve operations. The ability for various meters to communicate with AMR and AMI technology has become more important as these systems become commonplace.

  9. EPA Researchers Partner With WaterStep To Deliver Clean Water During Emergencies
    9/11/2018

    Following a disaster like the back-to-back hurricanes that hit Texas, Florida, and Puerto Rico in 2017, water systems can become flooded and unable to provide safe drinking water to communities. EPA researchers recognized the need for portable water treatment systems that can quickly and cost-effectively provide safe drinking water to affected communities following a disaster. 

  10. Using Flow Meters To Reduce Non-Revenue Water
    9/10/2018

    Utility managers are continually challenged to run water systems in the most efficient manner. Reducing non-revenue water (NRW) is an important component for system efficiency. In many states, regulators are placing caps on NRW or requiring reductions in the amount of NRW. Accurate and well-planned flow measurement can be used to locate areas of water leakage and reduce NRW.
