    How Giving Legal Rights To Nature Could Help Reduce Toxic Algae Blooms In Lake Erie

    August and September are peak months for harmful blooms of algae in western Lake Erie. This year’s outbreak covered more than 620 square miles by mid-August. These blooms, which can kill fish and pets and threaten public health, are driven mainly by agricultural pollution and increasingly warm waters due to climate change.

  • Forward-Looking Technology Anticipates Compliance Needs
    Forward-Looking Technology Anticipates Compliance Needs

    When a company stakes its reputation on delivering innovative technologies, products, and services, the specter of a changing regulatory landscape is considered more an opportunity than an obstacle. In this Water Talk interview, Mirka Wilderer, CEO of De Nora Water Technologies, discusses varying topics such as pharmaceuticals and nutrients in wastewater, the synergy of the company’s new MIOX and Neptune acquisitions, and how to address the growing concern over chlorate disinfection byproducts (DBPs) in drinking water. For example, De Nora’s new ClorTec Gen III onsite hypochlorite generators generate up to 3,000 lbs./day of chlorine-based disinfectants while reducing chlorate formation and cutting operating costs by 15 percent as compared to previously available models.

  • Satisfying LCR Compliance Measurement And Management
    Satisfying LCR Compliance Measurement And Management

    The challenges of complying with the Lead and Copper Rule (LCR) and other emerging regulations in a post-Flint world are high-priority for a variety of organizations — from government agencies, to public water systems, to individual facilities such as schools. This Water Talk discussion with Megan Glover of 120 Water Audit addresses the scope and execution of those challenges. It covers everything from providing point-of-use testing kits for sampling individual water spigots to managing overall Safe Drinking Water Act and LCR compliance through cloud-based software. Most important, it gives context to practical solutions for the many utilities and facilities coping with some level of lead exceedance.

    The Mainstreaming Of Potable Reuse

    With ever-growing demand for water resources, the reuse discussion has been building for years. More utilities are considering it, policy is being created around it, and new technologies are making it more efficient. To better understand the evolving landscape, Water Talk sat down with Brown and Caldwell's regional One Water leader, Allegra da Silva.

    My Most Personal Initiation To PFAS

    When I attended the U.S. EPA-hosted PFAS Summit held at the Horsham, PA high school auditorium on July 25, 2018, the education I received from state and municipal leaders focusing on the local problem was more than just a professional briefing. It was ominously personal, due to the fact that the Water Online editorial office where I work and drink water every day is served by a utility sitting smack-dab in the middle of one of the most concentrated PFAS hotspots in the U.S.

  • The Role Of Activated Carbon In Short-Chain PFAS Removal
    The Role Of Activated Carbon In Short-Chain PFAS Removal

    Water utilities around the country are trying to get a handle on their PFAS problem. While the presence of legacy PFAS is well known, lesser understood replacements such as short-chain PFAS are emerging as a major issue. The short-chain compounds are particularly important because they can be more difficult to remove. In this Water Talk interview, Adam Redding, technical director for drinking water solutions for Calgon Carbon, discusses the science and economics behind effective solutions for treating water for short-chain PFAS and other contaminants.

    Calgon Carbon Initiates Emergency Response To PFAS Detection

    Blades, Delaware, a small town in Sussex County, provides drinking water to more than 1,300 residential and business locations throughout the community. In 1981, the citizens of Blades voted to improve their water and sewage facilities by establishing a central water supply and tying all properties into the nearby Seaford Sewer System. By February of 1982, the project was complete and since then the town has had a clean and safe municipal water supply.

    The City of Paramount conducted a pilot study for arsenic, manganese and iron treatment system at their Well 15 site. The onsite pilot test was designed to demonstrate the performance of the Loprest Water Treatment Company treatment process proposed for the new treatment plant.

  • Early Leak Detection Efforts Already Yield Significant Savings
    Early Leak Detection Efforts Already Yield Significant Savings

    A large municipal water utility in the southwest operates multiple facilities that provide more than 170 MGD of drinking water to residents and businesses. The utility, which spans 100 square miles, is prone to leaky pipes because parts of its distribution system have been in place for nearly a century. Also known as non-revenue water, or NRW, these leaks significantly drive up the cost of production.

  • Groundwater Treatment Pilot Test Program Proves Successful In California (Loprest)
    Groundwater Treatment Pilot Test Program Proves Successful In California (Loprest)

    Iron, manganese, arsenic and hydrogen sulfide are indigenous to numerous groundwater aquifers. With the exception of arsenic, these constituents are more prevalent in deeper aquifers that are devoid of dissolved oxygen. This report summarizes the results and conclusions of a groundwater treatment pilot test program. This pilot test program was undertaken to determine the removal performance for arsenic, manganese and iron at the City of Merced’s Well 20 site. Chemical treatment processes required were also studied.

  • How The EPA Reacts To A Government Shutdown

    Did you know that the Environmental Protection Agency (EPA) had a published Contingency Plan in anticipation of the current government shutdown? I guess in hindsight, you would have expected it for an agency with 134 facilities dotted across the country. And in fact, it’s required by the Office of Management and Budget (OMB) under Circular A-11, Section 124 that all government agencies have plans for an orderly shutdown “in the event of an absence of appropriations.”

  • How To Structure Utility Data For Improved Efficiency
    How To Structure Utility Data For Improved Efficiency

    With a growing effort to ‘go digital’ in the global water industry, distribution and wastewater managers risk data inundation. But data sources from SCADA systems, pressure loggers, and stand-alone sensors can unlock valuable insights for more efficient operations and maintenance. Learn how to structure your system  to avoid data flooding.

  • Temperature Monitoring Provides Additional Checks On Microbiological Conditions
    Temperature Monitoring Provides Additional Checks On Microbiological Conditions

    Effective control of the microbiological environment in water distribution systems is one of the biggest keys to providing a healthy product. When it comes to processes for achieving this, the U.S. can some take lessons from Europe, where utilities are more likely to monitor temperature. Advanced flow metering technology that incorporates temperature monitoring provides a significant tool for utilities without the need for additional instruments.

  • Pushing Water Reuse To The Extremes

    Large-scale water-reuse treatment plants have had sustainable impact in populated areas where the volume of water to be treated and reused in a concentrated area makes them practical. Today, the flat-sheet membrane aerated biofilm reactor (MABR) technology that is delivering high-quality wastewater treatment to remote locations is poised to realize the promise of sustainable water reuse in those same locations.

  • Factoring Temperature Into Water Chemistry Reading Accuracy
    Factoring Temperature Into Water Chemistry Reading Accuracy

    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.

  • Defending Against Saltwater Intrusion
    Defending Against Saltwater Intrusion

    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.
