The Future of Water Science

WCP Online recaps the first webinar in WQRF's 2026 Summer School Series, led by Dr. Kaycie Lane of the University of Nebraska-Lincoln, covering what's driving innovation and adoption in the POU and POE market. The top-line number: the national POU/POE market is forecasted to grow at 7.8% annually through 2030. Lane's research identified three pipelines driving adoption (safety concerns, aesthetic concerns, and mistrust of tap water) and found that the three biggest barriers to adoption are affordability, lack of knowledge about treatment needs, and lack of knowledge about available treatment options. Consumer familiarity with POU/POE technology and upfront costs were ranked as the biggest drivers of innovation, while regulatory approval and treatment performance ranked much lower. In other words, the market is being shaped more by what customers understand and can afford than by what regulators require. The next WQRF webinar in the series is scheduled for June 30.

A new survey of 2,000 Americans commissioned by Culligan International reveals a pretty big gap between how much people care about their health and how little they know about their drinking water. The headline numbers: 76% say they're more intentional than ever about their health, yet 35% haven't thought about their tap water quality in the past year. Most people didn't know that arsenic (80%), nitrates (79%), and PFAS (74%) may be present in tap water, and half believe that water meeting government regulations has no contaminants or is based on the latest science (neither of which is accurate). Nearly half also believe that if water tastes fine, it's safe to drink. Despite all this, contaminants in water ranked as the top "invisible risk" in people's daily lives, above air pollution and food additives. The testing gap is big too: more than half haven't tested their water in the past year, and 57% believe all water filters provide the same level of filtration.

SpringWell published a timely piece connecting the data center boom to drinking water quality, and it goes beyond the water consumption angle that usually gets the headlines. The piece identifies three specific contamination pathways. First, construction runoff: large-scale site work involves blasting, drilling, and grading that disturbs soil and sends sediment into nearby waterways and groundwater, with rural well users bearing the most direct risk. Second, nitrate concentration: Amazon's data centers in eastern Oregon were reportedly cooling servers with nitrate-laden groundwater, then discharging wastewater with nitrate levels up to eight times Oregon's safety limits onto nearby farm fields. Third, chemical discharge: data center cooling systems use PFAS, fluorinated gases, ethylene glycol, and corrosion inhibitors, and in systems that aren't closed-loop, that chemical-laden wastewater can end up in ground and surface water.

Kinetico published a guide on naturally occurring water contaminants in North Carolina, making it a useful reminder that not all drinking water problems come from industrial pollution or aging infrastructure. The piece walks through four contaminants that commonly enter groundwater through geology rather than human activity. Radon can dissolve into well water and get released into indoor air during showering or dishwashing (there's currently no federal MCL for radon in drinking water, making testing the only way to know it's there). Arsenic enters groundwater through erosion of surrounding rock, has no taste or smell, and is regulated at 10 ppb for public systems, but private wells aren't regulated at all. Iron and manganese are the most common complaints: less of a health concern at typical levels but responsible for orange and black staining, metallic taste, and buildup inside plumbing and appliances. The guide is written for North Carolina specifically but the underlying geology story applies across many regions.
