Public water utilities in the US are facing a 5-year deadline to meet low parts-per-trillion limits for PFAS in drinking water. The EPA estimates that thousands of water systems will need to install advanced treatment processes to meet the limits. Utilities are eyeing several technologies to remove PFAS, including ion-exchange resins, granular activated carbon, and plant-based sorbents. But eventually they will need to replace such media, and what to do with the PFAS-laden spent media becomes the next challenge. #PFAS #watertreatment #waterutilities

We are not going to "treat" ourselves out of this #PFAS problem. Yes, we have to diligently address our current exposures and protect our communities. That involves BOTH safeguarding our water supply as well stopping the flow of PFAS into our economy. The article rightly notes that the treatment materials will need to be replaced and when they do they need to be treated as hazardous waste. There are 3 current options for PFAS disposal and destruction, all have notable uncertainties regarding their ability to complete destroy and contain PFAS waste. This is according to EPA's 2024 Interim Guidance. https://lnkd.in/efeyvXWi 1. Hazardous waste landfill 2. Incineration (not just any incinerator, ones that are capable of fully combusting fluorinated chemicals, still highly uncertain) 3. Underground Injection (yeah....) Let's think for a minute about the communities that often share a fence line with these kinds of facilities.... How about we do our municipal water utilities a favor and make their job easier and stop using PFAS in the first place by replacing them with #saferchemicals.

This is a concrete achievement to fight against water pollution. These initiatives need to be replicated, adapted and massively scaled-up if they are to have an effect globally as Water pollution is the Number 1 risk to human health ❗We need to deploy globally adaptation solutions to support municipalities to increase the resilience of the territories; the good news is that some solutions already exist as a proof here 👇 with the United States leading the path but regulation has to move faster to protect public health and ecosystems 💦 #depollution #pfas #expertise #watertechnologies #veolia #resilience #adaptation Veolia North America Veronique BOURGIER, PhD 🌎Sandrine Dubuc Karine Rougé Sarah Hercule-Bobroff Genevieve L.

Even if you aren't operating a drinking water plant, here's a quick read, courtesy of Bobby Magill at Bloomberg Law, on why you should care about the release of the drinking water MCLs for PFAS. 🎯 Bottom line, this is an expensive problem (follow Ali Ling for the economics of #PFAS). Drinking water plants aren't just going to take on the economic burden, they'll look upstream, Axine Water Technologies can help. #PFASdestruction

There have been crucial updates in effect for PFAS limits based on EPA's PFAS Drinking Water Maximum Contaminant Level final rule. The new limits set by the Pennsylvania Department of Environmental Protection (PADEP) are significantly lower, requiring almost non-detect levels to pass. Specific limits include: ☢️ Perfluorooctanoic acid (PFOA): 4.0 ng/L (20x total limit: 0.08 ppb) ☢️ Perfluorooctane sulfonic acid (PFOS): 4.0 ng/L (20x total limit: 0.08 ppb) ☢️ Perfluorohexane sulfonic acid (PFHxS): 10 ng/L (20x total limit: 0.2 ppb) ☢️ Perfluorononanoic acid (PFNA): 10 ng/L (20x total limit: 0.2 ppb) ☢️ Hexafluoropropylene oxide dimer acid (HFPO-DA): 10 ng/L (20x total limit: 0.2 ppb) You can refer to the publication in the Federal Register to stay informed and compliant with the new regulations from these persistent chemicals. https://lnkd.in/gj62Xde2 #EnvironmentalRegulations #PFAS #PFOA #PFOS #EnvironmentalProtection

On 10 April, EPA released a long anticipated final National Primary Drinking Water Regulation for six PFAS. This rule outlines both unenforceable maximum contaminant level goals (MCLGs) and enforceable maximum contaminant levels (MCLs). In the Insights post linked below, EA Vice President Paul Caprio, P.G., discusses the impacts to public water systems, cost management approaches, litigation, and treatment. #PFAS #MCL #DrinkingWater #PublicWater

For the first time ever, the US EPA has imposed a national regulation limiting the amount of six PFAS in drinking water, marking a crucial step towards safer water quality. This long-awaited rule, announced on April 10, will require all public water systems to start monitoring for these PFAS within three years, and then another two years to remove these PFAS from tap water. The agency has also made $1 billion in infrastructure funding available to help states implement PFAS testing and treatment at public water systems.

One of the significant challenges in removing PFAS chemicals from drinking water is the vast number of individual chemicals within this group, more than 10,000. US authorities caution that these substances can potentially cause cancer over a prolonged period. It's important to note that no single filtration or treatment technology is entirely effective at eliminating them. With such complexity, what are the available options for addressing this issue? And is it possible to filter out too much from your drinking water? #WaterQuality #PFAS #DrinkingWater #FiltrationTechnology

Interesting read on Yorba Linda Water District's #PFAS #water treatment plant. https://ow.ly/bGZI50Tvqug Did you know we have experts in PFAS and other emerging contaminants? PM me to see how we can help.

Global source water exceeds safe drinking limits of PFAS: The results of the study reveal that we have underestimated the amount of PFAS in source waters across the globe.  #Water #PFAS #DrinkingWater #SafeDrinkingWater #ForeverChemicals #ProtectOurWater #EarthDotCom #EarthSnap #Earth
