DRINKING WATER MEASUREMENT RESOURCES

• Do Water Meters Still Need External Transmitters?

  Expectations for transparency and reliability in water-metering infrastructure have risen. As a result, a fundamental question is emerging across the industry: if modern ultrasonic meters are already smart, why are we still adding intelligence outside the meter?

• Case Study: Groundwater DWTP (AK) - DEXSORB Full-Scale

  A DWTP client in Alaska detected elevated PFAS contamination levels in two groundwater wells supplying drinking water to 85 service connections. PFAS concentrations are provided in Table 1, where combined concentration of EPA PFAS6 was detected at 490 to 810 ppt.

• Using Historical Performance To Optimize Your Coagulation Control

  Non-intrusive ultrasonic technology provides precise, bi-directional flow measurement without process downtime. By clamping onto the pipe exterior, these systems eliminate maintenance and pressure loss, offering a reliable, data-rich solution for complex water and wastewater monitoring environments.

• Why Haven't Field Tests For Lead In Water Gone Mainstream?

  Given the maturation of sensor technology, the scientific and operational hurdles to portable lead analysis are somewhat surprising — but surmountable.
• Understanding The Limit Of Detection

  Accurate low-level turbidity monitoring requires a deep understanding of detection limits and the variables affecting measurement sensitivity. Learn how refined laboratory techniques and standardized spiking protocols ensure precision in demanding water treatment applications.

• Legionella And The Need For Next-Generation Detection: Steps Water Utilities Can Take To Alleviate The Risk

  As water systems grow more complex and climate patterns shift, Legionella is emerging as one of the most persistent and underestimated risks in the built environment. The threat to public health from Legionnaires' disease will likely further escalate unless decisive action is taken.
• Office Of Naval Research Contract Leads To New Chlorine Sensor Technology

  Developed from U.S. Office of Naval Research requirements, this multiparameter chlorine sensor offers extended maintenance-free operation, flow-independence, and automatic compensation for reliable, in-pipe monitoring.

• HAAs In The EU: Monitoring For Haloacetic Acids Under The Drinking Water Directive

  In this Q&A, Dr. Elke Süss of Metrohm addresses the urgent need for haloacetic acid testing in response to “one of the most significant updates to EU drinking water monitoring in recent years.”
• From Theory To Precision: ORP Monitoring As The New Standard In Water Treatment

  On numerous levels, oxidation-reduction potential (ORP) outperforms the presently predominant metric for evaluating disinfection performance.
