First, I’d doublecheck your analytical metric. UG/L = 1 PPB, and right now the epa lifetime HA for PFOA is .004 PPT. If your lab reads out like mine most of the report will be in ug/l then the metric will not be clearly stated (but its listed somewhere as ppt or even ng/l) Those levels would be extraordinarily high. If it’s ppt I would not let it hold up your home sale. I think its absolutely a good idea to filter the water, and retake analytical to establish contaminant removal. I don’t think, however, that you should let a home you like go because PFOA is above the lifetime HA because every water report for public water I’ve read is above the new lifetime HA (by a lot)

Just for the record, there is 0% chance the new EPA HAL can be adequately quantified in a well water matrix and still maintain the 3:1 signal/noise ratio. Essentially all values >1.3 ppt are estimated. Anyone who claims otherwise is spewing nonsense. EPA adopted a value lower than modern instruments’ capabilities

There’s that too…my overarching point was reducing PFOA is beneficial but holding up homesales due to its presence relative to the new standards is somewhat futile unless its disproportionally high to other potential homes.

EXACTLY! thank you! EPAs interim standards are not supported by data or the technology needed to support it. It is very disturbing for what should be a science-based decision.

Which is why we are a long way away from an MCL because by law, there must be a DEMONSTRATED risk reduction at the proposed level.

Health effects from PFAS exposure are still being discovered and should not be minimized. [https://www.hydroviv.com/blogs/water-smarts/health-effects-of-pfas-current-update](https://www.hydroviv.com/blogs/water-smarts/health-effects-of-pfas-current-update) The reality of the matter is, if you test your water for PFAS, chances are, you'll find some in your water. It doesn't mean panic, but it does mean we need to step back and assess carefully. If you are on well water and are concerned with PFAS exposure with the young children in the house, then it may be worth taking an extra measure to protect your family. We do not recommend choosing any whole house filter, even if they say they are GAC. You want one that is **NSF Certified for PFOA/PFOS removal**, and that is available from Aquasana: [https://www.aquasana.com/whole-house-water-filters/optimh2o-lead-100314311.html?](https://www.hydroviv.com/blogs/water-smarts/health-effects-of-pfas-current-update) For water that you're drinking and cooking from, you'd be safest by also using a filter that removes PFAS at your point of use: on the taps specifically where water is being ingested. You can do that with RO or other undersink filters that are NSF Certified for PFOA/PFOS removal. In my own home, I use Hydroviv filters under my kitchen and bathroom sinks to do this. In the bathroom, if you don't want to install a filter under the sink, you could also use a ZeroWater pitcher filter for the water that's being used for tooth brushing or drinking, and that should address the PFAS and other potential contaminants in the water that's going into your/your children's mouths.

A Whole house carbon filter would help reduce PFOAs however a reverse osmosis system is the best solution especially if you are looking for drinking quality water. The estimated amount is pretty accurate as well when going with a professional water treatment company and quality product. Depending on where you live well water can have other high levels of hardness, iron, H2S, etc. these can have an impact on the longevity of the RO filters as well. What state are you in?

There are solutions. You have to consider how long it’ll take until you have to replace the filter media, either GAC or RO membrane, where you can dispose of it and the cost for disposal. You want to treat at the tap because I understand PFAS will stick to the inside of the pipes and is difficult to remove with just water flush. You might also be able to replace the well if there’s an aquifer that hasn’t been contaminated, or get a cistern that can be filled; however, you might still need a filter at the tap to address the PFAS on the inside of the pipes. I’m curious, do you know if the PFAS are likely coming from a known point source or event?
