DRINKING WATER CASE STUDIES AND WHITE PAPERS

• What Is PFAS?

  PFOA (perfluorooctanic acid) and PFOS (perflurooctane sulfonate) are organic synthetic chemicals that have been used in manufacturing a multitude of industrial and consumer-based products including coatings, carpeting, and fire-fighting foams. Over several decades, they have contaminated the environment, specifically our drinking water sources, causing significant health concerns that recently prompted the EPA to take action.

• From Challenge & Prize Competition To Test Prototype: The Nitrogen Sensor That Could Change Residential Onsite Wastewater Treatment

  More than one in five households in the United States depend on septic or onsite systems to treat their wastewater. These systems provide critical water quality infrastructure, but they usually are not designed to remove nitrogen to the point that sufficiently protects coastal marine ecosystems. As a result, septic systems are known to contribute to eutrophication (excess nutrients), hypoxia (low levels of oxygen), and harmful algal blooms in marine and estuarine waters.

• Efficient Carbon And Ion Exchange Media Exchange

  This document outlines the essential steps required to exchange spent media, including disposal of spent media.

• Pembroke Desalination Plant: Malta

  LG Chem NanoH2O™ membranes delivered excellent water quality water at low energy costs at the largest RO desalination facility in Malta

• Optimizing Leak Detection Using Virtual District Metering Areas (vDMAs)

  Today, progressive utilities are using digital technologies to create virtual district metering areas (vDMAs), eliminating the limitations of the physical DMA by utilizing data to provide actionable insights into the condition of their networks.

• Modern Solutions For Aging Water Systems: AMI And Beyond

  Lessons from two communities on the benefits of advanced metering infrastructure.

• Smart Meters With Integrated Valves Promote Long-Term Savings

  Picture this common scenario for a water utility: A past due account triggers multiple notices to a home, but with no response from the customer, a crew is sent to shut off service. Throughout the process, the municipality racks up other labor costs, including personnel needed to create the work order and a return visit by a crew to restore service once the account is current.

• Electromagnetic Meters And Ultrasonic Meters — A Comparison

  Water and wastewater professionals rely on accurate flow measurements for process operation and regulatory compliance. Selecting the best flow meter for each application is essential to obtaining accurate flow data.

• Reassessing The Value Of Water Reuse In Process Efficiency

  In many industrial applications, water is not part of the final product but an important process facilitator — for cooling, cleaning, etc. Like energy, it can quickly become a major expense and, therefore, an important target for cost control. As potable water supplies tighten or become increasingly expensive, reuse is becoming a more attractive alternative. Here is some of the information needed to evaluate the opportunities it offers.

• LCRI: A Shift To Mandatory Service Line Replacement Within 10 Years

  Mandatory LSL replacement is a fundamental shift from the LCR in its approach to service line replacement, moving from a trigger-based approach to a mandatory, system-wide replacement mandate.
