PFAS in the garden: should we be concerned?
Вставка
- Опубліковано 5 лют 2023
- There's been a lot in the news lately about PFAS (per and polyfleuroalkyl substances)--with more information coming out regarding PFAS contamination in our water supply and soil, it is something to consider when we are putting things into our garden! In this video, we discuss some of the concerns we have with PFAS in regards to the garden.
Here are some of the things I consider when looking at potential PFAS contamination in the garden:
-Compost/soils: studies have found that nearly all composts are contaminated with PFAS. The lowest contamination occurs in compost made from plant materials. Avoid composts made with biosludge/biosolids. When buying bagged soils, look for the OMRI organic certification, which ensures the soil isn't made with biosolids.
-pesticides/herbicides/fertilizers stored in fluorinated HDPE
-potential contamination from recycled paper products

In this day and age, it’s very hard to really garden organically. My parents did, but we were also a dairy farm. My dad was way ahead of his time when it came to what the animals ate and use of chemicals. He knew what ever he used, it ended up in the food chain. That wasn’t acceptable to him so we did a lot of things ‘ the hard way’ in order to prevent leaching chemicals into the groundwater and soil. Thank you for this reminder. Very informative.
Yes we all should be worried about PFAS. The problem will only continue to get worse until people start caring about it.
I wasn't even aware of Fluorinated hdpe, great video ~Wisconsin
Super interesting... thanks for doing all this research! Chemicals have definitely been top of my mind in my farming and I've been adjusting as I go... not quite the same as PFAS, but I always give a HUGE caution when people suggest using straw as mulch because so many of the fields are sprayed with roundup etc..., in my opinion: leaves are probably the safest mulch someone can use. Definitely agree with avoiding manure! I worked on farms growing up... and people don't realize that what the animals eat greatly impacts what's in the manure - and most manure is NOT coming from organic, no-chemical farms. I definitely used the cardboard method earlier on in my no-dig journey, but have moved towards solarizing an area and then top-dressing with 2 inches of compost and broad forking it in. But now I'm wondering what those silage tarps are made with. 🤔 Regardless, recent soil tests show that all my beds are now at optimum levels of nutrients so I'm now moving into maintaining them with cover crops and the small amounts of compost I can make on my own property, which I'm pretty happy about!
Until a smoke plume from CA rolls across your state and it rains. There is no escaping it. It’s not just PFAs that have been mainly in the news coming from fire fighting foam. That is the biggest concern- the run-off.
@@dustyflats3832 Yeah, it's a valid concern. I know in WA, my state has banned the use of PFAS in fire-fighting foam... and are phasing it out in everything else, but the impact of using it in other states will stay play out across the country.
Thank you. I feel like people don't care about these chemicals in their food. But, good to see your video.
OMG I am so glad I found you! My husband and I are working on starting a regenerative farm and I see sooooo many people suggesting the use of municipal compost. I haven't personally done a lot of research on it yet, but with all of the literal TONS of waste that gets dropped off to these sites every single day without close monitoring, it makes sense that there would be quite a few contaminants. My mind has always gone to chemically treated wood, plastic contamination (I've generally seen A LOT of shredded plastic bags), and biocide residues, but for some reason I never thought about PFAS. Thank you so much for providing references on this and highlighting the dangers of using municipal compost in gardens!
This was SO educational, I had no idea paper products could be a source of PFAS and was completely guilty of throwing paper products in the compost and garden. A-mazing video, thank you for sharing!
Great info. Thanks for the bloopers at the end! The EPA does have recommendations for point of use filtration; Granular Activated Carbon, Reverse Osmosis & I believe Ionization (going from memory here). This is the first year (2023) that the EPA is requiring testing for PFAS through public water systems, but no regulations on filtering yet, mainly because they don't know what to do with the filtered materials, etc. Just my humble opinion from reading publications.
Great video, I unknowingly drank PFAs for years in one of the most contaminated areas of America. Hoping to someday grow my food in an area with less contamination
Great info. Thank you for sharing your concerns. I actually saw a news story on this topic last night. Something to definitely be aware of.
When I was working with radioactive materials in my daily career we used the safety principle of keeping exposure As Low As Reasonably Achievable (ALARA) - as you say, when talking about a family of contaminants that we are already seeing in widespread use, the best thing to do is to take what reasonable steps you can! For those of your viewers who can't switch entirely, limiting the amount of time things are stored in plastic containers and keeping the containers cool will minimize leaching. Chemicals at a higher or lower pH will leach more than more dilute ones. It's more important to monitor anything that's going to directly go into your soil than anything you'll be removing or that only transiently touches your soil - water hoses are likely the lowest source of contamination whereas additives to your soil are the biggest. (The leaching thing applies to hoses too, if you store them dry and cool, you will have less of anything leaching into water.) Your breakdown of contamination sources was excellent, just wanted to share some QA chemistry thoughts!
Thank you so much, that is excellent information and very helpful!!
Water Right makes non toxic hoses and work amazingly. They are a bit pricey, but worth the investment.
@@victoriamartinez8783Water Right's hoses seems to be made of polyurethane, which I believe contains PFAS. If this is the case, what makes the hoses non-toxic?
Great information, thank you!! I’ve had this on my list to do research since I heard you talking about it 😊
Thanks for addressing this emerging issue. 👍
Excellent info. Thank you for addressing this issue.
Fabulous information, thanks for sharing.
Appreciate the info! I actually had not heard of PFAS
How about plastic propagation containers from Epic Gardening? Like those 6 and 4 cells very sturdy containers? It doesn't show on the web if it's saved from PFAS, but I saw on your previous videos you used them.
You have given me alot to think about in the garden 😊Thank you for the information. Very helpful…just a little scary ❤
Information is power!! 🥰🙌🏻💪🏻
It’s sad news because all of the things like composting and using cardboard to be better eco conscious is now horrible to us. I just added cardboard to my start my flower beds and added milogranite to my lawn! (Barf uggh) Can you please do a video on new ways to garden eco conscious in a heavily pfas environment ?
Yes ❤ working on it!!
Thank you for all the information! I didn't know about pfas in all those different things! I would also love to hear more about gardening/growing food in a heavily pfas environment!
Thank you for this informative video! My goal is always to keep our place as healthy as possible for us and future generations.
Very informative ,thank you
Thanks for sharing! What are your thoughts on the plastics that make up drip irrigation? I’ve always worried about drip tape and wondered if there’s a safer option that’s still as water conscious
Thanks for info I've been using cardboard but can easily switch to leaves which I have in abundance and been using with cardboard.
I read an article awhile back. PFAs were found in wild and aquatic life in WI, MI, ME and FL where tested. Some major fertilizer companies should be labeling that the use human sewage instead of giving it a pretty name. Everything from oil change businesses to salons add to that sludge.
There is no way to get around it. I’m waiting to see what all the fire retardant used in CA and the fallout over from the smoke that drifts over all states will cause. Unless you have a bio dome there’s no escaping human damage.
It’s been a big deal here in WI as fire fighters use the foam containing PFAs in practice at the airport and the runoff.
We've got fish in our river too toxic to eat here in Wilmington NC
Thanks🌞
So glad I through away almost all of my non-stick pans and cooking ware years ago.
Thank you for sharing! I was just about to use cardboard but am now rethinking. I wonder if paper bags are the same probably/possibly?
In my country they found pfas in chicken eggs from hobby farmers. They don't know how it got in the eggs yet. Could be from the land,their bedding,their food or water. They don't know yet but its in the eggs so they advice people to not eat many eggs or any.
When did they have to start disclosing that it was in the water supply have you seen that information anywhere? When we got our whole house filter and I saw the EWG report three years ago it wasn’t on there fast forward to now and I see it that it’s disclosed. Also thank you so much for this information and bringing more light to this a topic that we all need to be aware of. I would also venture that people need to be mindful of the leafs they use.
What whole house water filter do you have? I'm currently shopping for one for my house.
You mentioned containers that hold fertilizer may have pfas, what about the packaging soil, or compost are packaged in?
You also mentioned be mindful of cardboard for smothering as a no dig option. Would that include plastic? Or like landscape fabric? I don’t have leaves in my yard mainly straw and that just kills everything and worsens our clay soil. What would be another option for no dig and no chemicals to clear an area?
If you can’t get hands on leaves, smother with wood chips to kill off existing vegetation. It’s a pain, I know.
💚💚💚
Do you know if hail netting is coated with pfas?
No, usually PFAS is for waterproofing fabric. Hail net is made of a plastic fiber and isn’t coated in PFAS
What happens when you run it through a worm bin
Worms will not get rid of PFAS unfortunately.
not to mention the ink on most cardboard
The 2019 movie "Dark Waters" was based on a true story. The one thing I took away from that movie and book was that 99% of the world population at that time had teflon in their cells.
You know.
Everyone here is probably in the clear.
But considering these are the problems society is left with.
Really shows the ineptitude of previous generations ability to care for the planet long term.
The old ways have to stop.
We need to stop poisoning nature.
We need more regulations
