For more than 16.5 million water-utility customers in 33 different states, contamination caused by per-and polyfluoroalkyl substances (PFAS) is a source-water issue that will not go away for a long time. What are the practical options for community water systems currently confronting this challenge? Here is an overview of several treatments and their relative successes against a wide variety of PFAS compounds.

Why Material Selection Matters
The Tri-County Water Authority (TCWA) was formed in 1991 as a not-for-profit water utility serving portions of Jackson, Cass and Bates counties, Missouri. When the system was first established, about half of the pipe installed were ductile iron and half were plastic PVC. Today, the authority’s 120 miles of pipe are approximately 75% ductile iron and 25% plastic PVC.
AMERICAN® Products Support Paulding County’s 20-Year Effort To Ensure Safe, Sustainable Drinking Water
More than 13 miles of AMERICAN ductile iron pipe and nearly two dozen AMERICAN Flow Control® resilient wedge gate valves with Flex-Ring® ends are playing an important role in providing safe, affordable drinking water to fast-growing Paulding County, Georgia, one of the only counties in the metro-Atlanta region without an independent water supply.
Iron And Manganese Removal Without Chlorine
Iron or manganese removal commonly involves injecting chlorine or potassium permanganate, followed by filtration with sand or coated greensand media. Chlorine can affect the taste and odor of the water as well as involve high levels of maintenance and costs.
Water Utility OT vs. IT — It’s Not A Battle, It’s A Balance
The chemistry of optimizing water/wastewater treatment extends far beyond chlorine and oxygen. It also involves synthesizing productive insights from the flood of IT data generated by operational technology (OT) sensors, instruments, and control systems. Here’s how better operational intelligence strategies are helping IT and OT personnel collaborate to make processes more cost-efficient.
Wastewater Treatment Plant Realizes The Importance Of Using Genuine Replacement Parts In Its UV Disinfection System (Case Study)
The UV system installed at the Lucas County Water Resource Recovery Facility includes a total of four banks, with 48 UV lamps per, for a total of 192. The facility was experiencing disinfection inefficiencies and, even after repeated inspection and analysis, staff couldn’t figure out why. They started to question if the issues were stemming from the use of non-OEM, non-genuine UV lamps, quartz sleeves, and ballasts.
Wastewater’s Worst Case Scenarios
Real-time data is the first line of defense for wastewater utilities. A data infrastructure serves as a window into critical operations, allowing employees to optimize equipment performance and hedge against risk. It is often the most economical solution as well: in many cases, utilities already have many of the core elements for an actionable data infrastructure for improving decision making.
