As federal maximum contaminant level (MCL) recommendations for arsenic in drinking water are being reviewed, US utilities are preparing for more stringent regulations.
If faced with reducing its treated water's arsenic concentration to 5 μg/L, the City of Alamosa, Colo., would need to increase its ferric chloride dose—raising supply, cost, and operational concerns.
To avoid these issues, the city explored a new technology that generates a ferrous reagent via an in situ electrolytic process to replace bulk ferric chloride.
The electrolytic ferrous reagent removed arsenic to below 5 μg/L, reduced permeate manganese levels, and improved effluent quality with a far lower coagulant dose.

Water service providers need to prepare for more extreme weather events in a changing climate.
A geospatial analysis found that differences in boil-water advisory lengths issued during 2021's Winter Storm Uri were based on the population served and rural or urban location.
A cross-sectional survey showed that many individuals were unaware of or confused about the advisories that were (or were not) issued.

Is water a need or a right? It seems this question comes up more and more, and perhaps that is a good thing. Still, I also see many water professionals getting hung up on issues surrounding the difference between the two—need versus right. Certainly there are differences, which leads me to wonder whether some of the debate could be simplified.
For example, we all need water. That seems easy. For me, every morning starts with water. A big glassful before I walk my dog—she, too, enjoys some morning water, albeit from her bowl. Our water is safe to drink, and while I am thankful that it is, I confess that, early in the morning, I (and probably my dog) don’t stop to appreciate the work that went into providing me with this safe water. Because there is no substitute for it, it seems clear and undebatable that water is a need for all of us—pets included.
Is water a right? At this point, the debate becomes more complicated—we start to get hung up, think harder, and often become frustrated with others who don’t see water the way we do. To a great extent, I think many of us instinctively jump to the conclusion that a right to water—which is more accurately framed as the right to have access to water and water service—implies that the water and the service are free. It's the assumption that water should be free that disturbs us.
It is an easy leap to make. For example, AWWA's annual State of the Water Industry report repeatedly ranks replacing aging infrastructure as the top concern of water professionals. Investing and reinvesting in infrastructure is, of course, critical to the sustainability of water services. The cost of these replacements is paid, directly and indirectly, by customers who are paying for their water service. Thus, the sustainability of water services is dependent on customers paying for the water—not getting it for free. As a result, we cannot support a right to water concept because if water service were free, the service would not be sustainable.
On the other hand, if water is a need with a price, what does that mean? To answer this, it is helpful to understand the best practice for setting the price of water. The approach is called cost-of-service rates. While AWWA's Manual M1, Principles of Water Rates, Fees, and Charges explains the methodology in detail, the short explanation is that cost-of-service rates, when done correctly, fairly and equitably generate revenue that covers the utility's cost of providing water service to each class of customers. What cost-of-service rates do not do, however, is set rates that address a customer's ability to pay. This is because once cost-of-service rates are tinkered with to address affordability objectives, the integrity of the cost-based rates is compromised and, quite possibly, they will not generate enough revenue. While this creates a conundrum for marrying cost-based rates and affordability goals, these rates are still the best place to sta
