- Does chlorine in tap water harm beneficial microbes and bacteria in my garden soil?
Will the bacteria recover quickly?
How much chlorine is in tap or city water?
Should I remove chlorine from my tap, drinking or city water?

I have noticed over the years that people recommend watering the garden with water that does not have chlorine in it such as Tap water. The premise of this statement is the bacteria I your soil are a key player in the nutrient cycle and chlorine kills bacteria.
So today I thought today I would test this garden assumption.
The water treatment plant that provides my drinking water has been recognized as using the gold standard for water treatment. After getting the water from the North Saskatchewan River it is initially shocked with Sodium hypochlorite or bleach. This does a great job at killing bacteria and other pathogens that may be in the water. The downside to using bleach is the chlorine decays rather fast once in contact with the water and air.
In order to keep the water safe while shipping ammonia is added to the water creating chloramine. This essentially stabilizes the clean water until it gets to you to make sure it is safe for you to drink.
It is really important to note that even at the highest levels the chemicals used to sterilize and stabilize the drinking water here in Alberta are several orders of magnitude below what is considered to be mildly irritating to humans.
thanks for having a scientific approach to answering our question about chlorine and tapwater and to getting to the point and not wasting our time. Love the video!
We are getting some good questions answered, that no other site has, except you
and Pat are answering.
MrMac5150 I am glad that both OneYardRevolution | Frugal & Sustainable Organic Gardening and I can help out ;)
The internet is awash with gardening tip sites, blogs, etc.. discussing all of this. It's like you've never searched the internet.
On the impact on beneficial microorganisms yes. About the assumption that a minimum level of these chemicals in potable water does not harm human; this is an opinion based on old science knowledge paradigm although many studies start to show that repetitive adsorption of negligeable harmful chemical add up and cause structural diseases.
This totally answered my questions! Thank you!
This video eradicated a long standing paranoia of mine. Thank you
Glad I could help!
Again, thanks for the work. I know how long videos can take to plan, shoot, edit and present. This video was clear, to the point, and really presented great info on how tap water really doesn't cause a problem. Thanks. I might attach this to my compost tea video I will be making. I recommend watching this for the scientific approach.
Gary Pilarchik Thank you Gary its quite an honour to have you comment here! This one took weeks and I am sure glad it turned out well!!
I would be honoured to have this support your videos!
You are right to date Tap water is not harmful!!
What he said..
I believe that collecting rainwater for the garden from your home or other buildings would remedy any chance of chlorine, heavy metal or ammonia contamination and microzoa harm. Was your chlorine sampling in the tap water free or total chlorine? the difference between 2.0 and 1.3 is significant in my eyes as 2.0 is over 50% higher than 1.3. The proof though, is in the bacteria and other microzoa counts in the samples. On the flip side, I have seen some hydroponic gardeners use a bit of chlorine bleach (household 5.25 - 6%) to "clean up" dark roots on, say strawberry plants. To me, if the dark roots deliver plenty of berries, turning them white with bleach is purely aesthetic. I think about some of this from an aquarium perspective. would I place anything as toxic as chlorine in any of my aquariums? NO. The same types of bacteria that feed the plants with the fish waste in the ammonia, nitrite, nitrate cycle also convert minerals to plant food in the soil. I place tap water in a 5 gallon bucket at least overnight before adding it to any aquarium or I use DI water. In the tropical fresh water systems that I use, the plants grow vigorously and have to be thinned on occasion. there are so many cycles of nutrients through the microzoa in the soil and water, that I think it is prudent to maintain non-toxic inputs to their environment. Great video and very descriptive! Thanks.
The analysis represented total Cl in the water.
I have had a few comments about the impact of Cl on fungi and look forward to investigating. I do rely primarily on rain water in barrel and free falling. That said i am less worried when I have to use Tap water.
1mtstewart Steve said his water is treated with Chloramine which is not the same a Chlorine. Chloramine is not as effective as Chlorine as a disinfectant. Chloramine also does not volatilize from the water like Chlorine does. Our local city water is treated with Chlorine, if I use it during dry periods because my rain water supply is depleted, I collect it buckets and let it sit in the sun at least overnight. It would be interesting to see the test done with straight chlorinated water out of the tap instead of Chloramined water out of the tap.
I have often pondered that theory of chlorinated water harming garden ecosystems, but considering that we drink the water, that in itself should say that it is not harmful at the point where it is dispensed from our homes. At the treatment plants as you stated they are hit with a high dose, and that kills them, but it doesn't linger and there is no need for it to linger in huge quantifies. Case and point, swimming pools have to be constantly and heavily chlorinated because its potency and effectiveness wears off over the course of a few days. If one application is missed, then the algae will immediately start growing. Great scientific research and rock solid data.
ayatti26 I had thought the same. The levels in pools are so much higher than these results its would seem rather straight forward. That said there are products out there that perpetuate the myth in order to sell products. That said more research is required as always in science ;)
Thanx a bunch man for going thru the trouble of doing all that. I don't think you could have gotten any more thorough than that explanation and experiment. I have always wondered about all those topics you mentioned. Stay safe in these trying times.
Thank you! Finally some real test results. I wish someone would do this for water in US.
This is my new favorite Garden series.
That is fantastic ! There are 20 or so of them :)
Saved me from bucketing 100's of gallons of water! Thanks for your informative videos.
Stephen, excellent video on the impact of tap water on soil bacteria!
OneYardRevolution | Frugal & Sustainable Organic Gardening I am glad you enjoyed it Patrick! I sure was surprised when I got the results back.
Stephen, your new intro is terrific. well done. your videos are very help, keep them coming. thanks.
Thank you my friend ! I appreciate it ! I will keep them coming as long as you keep watching, sharing ext...
Nicely done sir!
I appreciate the fact that you totally geeked out !
I adore your videos. They bring joy to my brain.
Another excellent video! It would be impossible to water all of my garden without tap water, but it always crossed my mind, and now I know I don't need to worry. I love how you are busting one myth after another. Just today, I was debating with a gardener who was telling everyone to always put epsom salt in the ground around all tomatoes.
The Experiment We have long dry spells here and it gets bad. I could not garden in the spring if I had to only use reserves ;)
I am glad I could inspire conversation with those whom promote methods that just don't stack up like Epsom Salt!
Epsom salt is beneficial for the nutrients it provides. I use it as part of my fertilizer regime
Thank you for this mini-thesis! Great job! Very useful!
I'm a new subscriber, I've found your videos informative, intelligent, not opinionated, not self serving, nice change!
Thank you so very much Carl! Welcome to the community and please let me know if you have any questions at all!
Thank you for a well investigated issue. I'm trying to learn about Chloramine and the effect it has on the fish in my aquaponic system, which is a slightly different issue but it was good to know how chlorine changes as it's distributed. I currently set out buckets of water for a few days prior to adding them to my system, but I'm learning that the Chloramine is still in the water.
I applaud you sir! This is the way I wanted my question answered! You could cover any topic this way and I'm there with my notepad!
Interesting results Mate. Still need to age the water here due to fish not being very partial to chlorine or chloramine.
Cheers.
RobBobs Backyard Farming Fish are a whole new game and I am actually professionally able to speak about it. concentrations as low as 0.2 ppm can harm fish. bacteria however are able to buffer it out ;)
Ageing water will not remove chloramine.
@@topsieBeezelbub It will when exposed to sunlight in an open top container it can. VitC (ascorbic acid) is a much faster method though. 😉
@Randy Cory You sir are a loser. Do you really think folks don't know you have 2 profiles & post the response as well.. Get a life.
@@RobsAquaponics I suspect those accounts might be run by a robot, it seems like there might be thousanands of those posts.
Nicely done chain of custody!
Have you done a study like this on soil fungus as well? One of the other things you may want to test is the presence of heavy metals in the town water, as the chemicals added in treatment make the water slightly acidic and this leaches off metals from the piping as it travels to your residence. I'm currently trialling the use of caravan water filters to see is this improves the health of my garden plants.
Excellent video Stephen! Luckly I don't have to worry about chlorine because the water comes straight from a spring 100ftaway and is naturally filtered with peat and moss. It then goes through a UV light to kill any microbes on the spot so no long term effects :)
That is great !
While the scientific method and UA-cam are rarely mentioned in the same sentence, I'm happy to find that to be the case here.
John Smith That is what I want to bring at least to the gardening corner of UA-cam! I am glad you enjoy it my friend!
Stephen
I am somewhat of a simpleton when it comes to analytical tests. However you do a great job of posting results. I am grateful you are doing all these tests. I am arriving at the conclusion what I have done is good enough. You are proving soil amendments are primarily an extra cost and the added benefit can be marginal.
What I have done is what you and Patrick recommend. That is free and local resources. This I have primarily done, by using wood chip mulch, which I admit, I did not apply perfectly, that is inches and with green leaves, I over did the inches and leaves were non existent in much of it. I also use compost primarily of leaves vegetable scraps and coffee grounds. This process is slow but what the heck, it does not cost much. The wood chips truly keep me from having to water, keeps the weeds down, and will eventually make a rich cover for the soil.
Thanks for helping me evaluate what is happening here because you do it there.
Steve
+Steve Gillespie Steve I am so very happy I can help you my friend! What I hope to do is help people grow food at home using the best possible scientific evidence. Now is my science the best out there no... there are limitations to the Citizen Science I am doing but it is evidence and I hope people take the time to review the evidence and us it to help make their garden decisions.
Gardening is a learning experience for the best of us and as such let me know if you need any help at all. I am always here to help!
Thanks
Stephen I re-watched the video you recommended again and got something new. You are the man!
Steve
Steve you are the man ;) I'm just a garden bum with a camera lol. I am really glad you got something new from the video. It is always my goal to make these videos useful to at least one person!
Excellent information
This is a wonderful and very informative video. Thank you for the detail oriented process and documenting it. I've seen many short videos claiming the opposite with nothing to back them up
Great work and thank you for answering this gardening conundrum.
***** I am glad I can help! These ones take months to put together. I started this one in early April ;) get the study design together, sample wait, add new samples write ;)
this was awesome! Good video very simple to understand.
Glad I could help!
woah woah woah !! nice new intro and logo lol gotta upgrade every now and then, I understand. Sticking to my rain water catchment... up to 900 gallons of storage now.
Permaculture Prepper Thanks my friend! I love the new intro and such ;)
If given the opportunity I use my rain barrel. unfortunately we have not had rain in 5 weeks :(
Permaculture Prepper Up to 900 gallons of water storage. That's great! I planning to buy larger containers for next winter. We need to save all the water we can in California. How long does 900 gallons last you?
not sure yet joe just added the 3rd IBC tote. its in my recent update. ill keep you all in the loop, but so far they are full and looking like they will stay that way if we keep getting rain.
That does sound great! on site storage like that would be nice!
I also am surprised at those outcomes. I think I will continue to use my filter however because my tap water smells and tastes strongly of chlorine.
Another test I would like to see is if fluoride is absorbed by plants.
Organic Gardening in North Carolina I bet you can ask your water authority for their analysis. there is no smell to my water here. You can discuss it with them to make sure your water is clear.
Fluoride was a part of the research for this episode and it does not impact bacteria and there is no evidence to date it is uptake by plants ;) just our teeth ;)
Good!
Organic Gardening in North Carolina why are you curious about fluoride? Are you one of those science deniers who believes that “fluoridated water is dangerous”?
nathan richardson flouride is a neurotoxin and a by product of the phosphate fertiliser industry. In my opinion there is not enough evidence to support that flouride is ever beneficial for our teeth but there is evidence that it calcifies your pineal gland.
You know what does whiten teeth, is anti bacerial, fungal and viral? Coconut oil. Need an abrasive? baking soda. missing out on that fresh breath? peppermint or mint essential oil which also kills anaerobic bacteria.
Best thing about it? No need to go get medical assistance if your child has swallowed a load of toothpaste. They can keep the toxins.
@@yamyams94 HAHAHAHAHH in "your opinion" hahahahahhahhahahah tell me again...where did you study chemistry?
An excellent video and I'm very surprised at the results. Thanks for taking the time to put our fears to rest :)
Perma Allotmenteers I am glad I could help!
Nice new intro and great video! Pretty thorough experiment. I'm sold on your results. Thanks for doing this!
MrChipGardener Months of work finally come together for a re-branding and one large study lol. Thank you for the kind words and really starting this whole series about a year ago !
Here in my part of the world, we don't get much rain at all during the growing season and it is very hot so irrigation is vital to gardening. I've always heard that chlorinated water was harmful to the garden but had no other choice. Now I will use tap water without worrying so much. Thanks!
GrannyBird Birdsong I am glad I could help my friend! no need to worry!
These results are great to hear. I did not expect it to not makena difference, but I did expect it to have some effect.
Thanks for the video! I've never had trouble with using tap water in the garden and am not really surprised by these results. If the choice is tap water or no water at all, the obvious choice is opening up the tap.
I agree. If I have rain water I will use it however it gets dry here !
Great info, Stephen! I've always wondered if chlorine really does harm beneficial bacteria like everyone says! Thanks for sharing your research! Love your new branding, BTW!
CaliKim29 Garden & Home DIY Thank you I am glad you enjoy the branding! The clip was a lot of fun to put together! I was sure surprised by the results ! No need for expensive filters.
That's very comforting to see the results. Thank you once again Stephen
Patrick Meehan I am glad I could help Patrick!
I like the work you did here and agree with these methods of testing. Good job!
AlboPepper Thank you my friend!
Thank you for taking the time to do this, it was an excellent and informative video!!
+Carmen CES It is my pleasure!
I thoroughly enjoy this video Stephen.
I have never question the use of my tap water for my garden and plus the plants are always green and healthy.
***** I am glad you enjoyed it Mary!! your garden looks great my friend!
Great study Stephen. I have been looking forward to this video for a while now. Like many others I assumed the chlorine in my tap water had at least a slight negative effect on my soil. Good to know it isn't much to worry about. I will continue to use my rain barrel though, as its just more convenient for me. Thanks for all the work you put into this.
Bryan Wickizer I use my rain barrel too ;) It is less of an impact to use ;)
I am glad you enjoyed the video and found it useful!
Thank you thank you good sir, you're answering important questions and doing research for free, much respect & love!
Thank you for doing this. This is exactly what I was wondering and you sir put in the work for all of us.
Great video, answered a lot of questions I have. However, I think I'm a little late to the party. As far as I know, chloramine (chlorine with attached ammonia molecule) does NOT evaporate. I don't even think distilling it removes it. Ascorbic acid works (Vitamin C) and other treatment solutions (think aquarium tank amendments) as well as some reverse osmosis filters.
This is a very good information. Thank you so much. I love how scientific it was.
I am glad I could help!
Thank you for this. I’m not convinced that a plate count technique was the appropriate testing method for measuring this. Soil analysis using a shadowing microscope would allow for counting the number of ALL beneficial microbes, not just bacteria. Bacteria are the bottom of the food chain in the soils food web world. Without the fungi, Protozoa, beneficial nematodes, microarthropods and macroarthropods, the nutrient cycling for plants (the poop loop) wouldn’t exist. If a soil is simply full of bacteria (which it often is) and nothing else, it’s not a healthy soil.
If you take fully complete compost that is complete with ALL the microbes needed for healthy plants and soil and analyze a sample using bottled water and then analyze a sample using city water-using a shadowing microscope-I suspect one may observe beneficial microbes struggling to survive.
ALL beneficial microbes, not just bacteria If a soil is simply full of bacteria (which it often is) and nothing else, it’s not a healthy soil - I totally agree!
Very interesting Stephen...I'm still sticking with fresh spring water I get from my property. Thanks for sharing.
Eco Oasis if you have access why not use the local resource ;) I use rain water as much as I can but it has not rained in a LONG time!
It's a wonderful piece of information. I also see comments in different languages, here is mine in Urdu.
سٹیفن، بہت اعلیٰ معلومات ہیں، امید ہے کہ بہت سے لوگ اس سے فائدہ اٹھائیں گے۔
VOTE4TAJ Thank you my friend! So far Google Translate has helped me reply back to those whom reply in other languages. I too hope many people will benefit from the work I do!
You just saved me some money! I was just about to buy a chlorine filter for my garden hose. I appreciate your approach to this and thank you!
Another EXCELLENT video Stephen! Well done! I had a hunch the damage was very minimal. This is very good to know!
Tommyr I am glad you enjoyed the video my friend. I actually thought we would see impacts but recover quickly.
i know im 3 years late, but as gary said, very well put together video, kudos to you and sub'd
I was about to watch about beneficial bacteria from aquariums but I was in the wrong section but then afterall your video was interesting to watch, even though I didn't read the whole title still relatable and worth watching...peace
Glad you stumbled on the video then!
That seems to be a clear answer to my question! Thankyou!
This question ocurred to me today while I was watering my vegetable plot with chloramine treated tap water.
It's good to see that using it is doing no long term damage to the soil ecology.
Thanks for the video.
This is a great experiment! I love your channel.
+Cosas del Jardín Thank you my friend! I am really happy you enjoy the channel!
so many interesting videos - so i subscribe for learning more !
Thanks ***** for put all efforts and times to make this test. This is one of the best the video presentation ever! Your explanation is very percise, educate & answer all my confusion before. I feel so happy with the test result that I don't have to purchase additional filter for garden Hose. Thanks again!!
Sohan Sohan I am glad I could help my good friend! This one took a long time to put together but it was well worth it!
based on these results your right no filter required!
This is fantastic! Thanks for doing this and presenting so well! I would love to see water tests comparing tap water to my rain barrel water. I've always wondered if the rain water gets contaminated by the asphalt shingles on my roof.
Awesome video I have wondered about this forever. I finally had a thought that someone has probably done a video like this. Thanks
Glad I could help !
amazing video.. I've always wondered this.
Great job on the video. The results were suprising to me even though I had never worried about my tap water being harmful to my soil. Thanks
They surprised me as well! I was not overly worried but I would have expected some reaction!
I'm addicted to these great videos!!!!
this is a great experiment. I'd would great to see some other people try to replicate it.
I certainly would love to see others do this work as well!
Very interesting!
I never really thought tap water was killing bacteria in the soil, because it just didn't make sense based on my observations.
My anecdotal experience is that tap water will keep my plants alive, but they won't do any growing, and they certainly don't thrive or put out new fruit. I have a theory that my tap water is either mildly stressing the plant, or somehow interfering with the absorption of nutrients. But the change happens way too quickly for it to be something to do with the bacteria in the soil.
Lately, my rain barrels have been permanently empty and it's been extremely hot, so I've been watering with tap water. Yesterday I tried treating the water to remove any chlorine or chloramine that it might contain, and the garden sprang to life overnight! Suddenly there were flowers blossoming, new growth, fruit returned to growing, etc...
This is anecdotal, so obviously it could be confirmation bias. But it seems like every time the garden gets watered with something other than tap water, it has an explosion of growth, and it doesn't cost much to treat the tap water before I use it. So I'll continue to treat the water. :)
Fantastic video. I'm always impressed by how scientific you work with your samples and get them tested at a Lab. Impressive work. :) --- I can't help to notice all the videos youtube placed in the right hand column, all pertaining to the evils of chlorine in tap water.
***** I am glad you enjoyed the video and the series my friend. I did notice that as well today. I might have wandered into an area filled with some opinions ;)
Love this video. Some of the filters are so expensive. I don't have that much money so I didn't buy any. My garden seems to be doing just fine without any. Thanks for the info :)
+OmgKittys78 Further to this video I am going to be releasing a follow up on the topic. It seems I was a few months ahead of some peer reviewed research that supports the findings here.
no need for expensive filters on most tap water!
Thank you for the kind words my friend!
Great video! I was wandering if watering my mango saplings with tap water would do them harm. As i live in an apartment i had to change their soil with wild soil, not bough, straight from a field!
I will leave the water in a bottle for days before watering them, so the chlorine lvls drop a little!
Thanks for sharing! There's a tendency to get caught up in the whole idealism of organic gardening and spend money you really don't have to spend to grow quality food (i. e. buying a filter to remove chlorine from Tao water).
Well there is a whole market around the industry and its hard to find out what's marketing and what's needed. It's why I do this series I want to know and am thrilled other people enjoy it as well ! That pine needle episode really got me going !
Well bless your heart man for doing such a great service to us all. It's so confusing with all the unsupported information on UA-cam. But, your's is scientific. I've been filling out 5 gallon buckets and leaving them t air for 12-24 hours and filling my 2 gallon watering can to water my vegetables garden. So, no more. I'll go back to using my safe for drinking water garden hose. Thanks for a great presentation.
I am so glad I could help my friend. I too find it frustrating when I can’t find information that has some research to it.
im a young man experimenting with compost tea formulations for hydroponic/aeroponic systems, and your videos seem very informative. i think im gonna have to subscribe.
Thank you Mark! I hope you enjoy the videos!
I still recommend this video to people all these years later
I appreciate that !! Thank you
You're like the myth busters of gardens
Its what I enjoy doing ;)
Wow, Debunking stuff left and right up in here. Love the details and explanations - thanks!
+wiitele that is my pleasure ;) I just follow the science!
thank you so much for doing this video its been something I have been concerned with. I will feel better watering with my hose now also.
***** I sure feel better about watering my garden ;) I am glad you enjoyed the video!
in water deposit fed irrigation systems, (such as BLUMAT) the water temperature gets a problem in hot summer due to its lower O2 saturation values in higher temperatures as you can see from aquarium tables. water poor in oxygen takes O2 from the soil & roots worstening their conditions. i'll cover the deposits by ivy & blackberry plants etc. for shadowing them.
I like your new logo. Another earth-shattering episode! Wow. I'm surprised, but not overly surprised. The last 2 compost piles I've made, I've used regular tap water and the piles turned out fine. It would be interesting to know exactly how long it takes for all chorine to evaporate from standing water.
Growing with Joe Thank you! I am glad you enjoyed the new branding! I am super happy with it!
I sure was surprised about these results. I bet the Cl would take 24 to 48 hours.
Very well done. Thank You for showing the test results. It showed it is OK to use tap water. Also, GREAT NEW LOGO...
iamnjorganic Thank you for the kind words my friend! It is ok to use Tap water ;)
I love the logo as well I am glad that everyone else seems to enjoy it!
Well thought out testing. Don't know about Canada but in the States different areas evidently use different levels of Chlorine. I lived in a few places that the chlorine smell of the water was so strong I couldn't stand to drink it. Would be interesting to see testing from those places.
***** It really would be interesting however the hold time on these samples are so short someone has to be there and have a lab available.
I have smelt the same a few times but that is usually after a boil water advisory and they have to purge the lines. They do tell everyone to run the water for an hour in every tap kind of thing. by the end the water is gone.
I want to thank you for the great video. I have always heard the u should leave water sit for 24 hours but have never seen any proof I spend hours filling pails with water and leaving them sit the recommended time. I bought a 250 gallon tank last year for next season. I am going to still continue to let my water sit but will not feel as guilty if I water out of the tap somedays. Thanks for the great work please continue. Especially since u are in my nex of the woods
+Wayne Loustel It is always good to meet local gardeners! I felt guilty when I used hose water but in light of this I am not worried at all. That said I prefer my rain water but tap is a good back up!
This is what we were looking for!
An interesting experiment and reassuring to know. Thanks for taking the time to run this testing.
Foodie Laura I am glad I could help my friend!
Like always, a great informative video, thanks Stephan.
***** I am glad you enjoyed it!
Thank you for all the work in bringing us this.
Eric White I am pleased you enjoy the work. it makes it worth it!
Amazing, love this channel and this series especially.
Thank you my friend ! The first Friday of every month I post one of these videos !
I hope you have a fantastic day!
phxtonash I did! I am a little tired but it was a good one!
in summer, i programmed 5 starts for my drip irrigation system each day, so i assume, that watering frequency also affects soil's microbes due to less time for their recovering from 1 irrigation to the next...
Thanks for a thorough test.
Hugh Janus I am glad you enjoyed them my friend!
***** I'm new to gardening, but I notice after a rain, I live in NYC, my plants seem to just grow more and look much better. Also, I filter my water.
There are a few people whom have said that. I wonder what the difference could be. I rely on city water only when I have to more so because I try to keep the costs down and tap water costs money ;)
Interesting.
Thanks for the comprehensive testing.
Shinintendo I am glad I could help!
We had a question, and by cracky you answered it!
I’ve been wondering about this topic for a while now. Great research.
Standing ovation! Well done, sir!
Great video. Certainly flies in the face of what most people believe...Thanks for your scientific approach to gardening. My own science background appreciates it.
I am glad it helps. Turns out this week a group of scientists figured out how to count the bacteria in tap water with out culturing. They found 8000 per ml. This is not to worry as all of them are good or neutral.
So if the tap water has some it should be no surprise the same water does not kill them in our garden !
That means the tap water was potentially the additive factor as shown by your numbers, right? Seems like another control you'd need to perform is to plate the tap water alone, and you'd likely see similar numbers. I'm afraid this new info blows up the use of plating to test soil bacteria disruption. I agree with the earlier concern that bacteria type and diversity is ignored, so this isn't a valid test. Reading about chlorination, it often inactivates and doesn't actually kill bacteria. This is why we it must be constantly present in the tap water, and why they don't just try to treat and then remove the chlorine at the time of treatment.
Also, another factor may be that given that chlorine acts as an inactivator as well as a killing microbes (this experiment ignored the rest of the food web including protozoa, nematodes, microarthropods, and fungi to name a few) chlorine could potentially disrupt the balance that healthy soil strikes in the constant struggle of aerobic vs. anaerobic, predator vs. prey, etc.
I really appreciate that you took the time to do this experiment. The world needs more, careful examination of how we use chemicals to protect and possibly harm ourselves and the other life in our ecosystem. Farmers have been doing it wrong for decades, wiping out their soil biology with conventional till, synthetic fertilizing, and systemic pesticides and herbicides.
Well, karlin, how about you do all those tests and then you can tell us your results. He is doing specific test to verify specific claims not testing for every single variable. Let me quote you "this experiment ignored the rest of the food web including protozoa, nematodes, microarthropods, and fungi to name a few", are you aware that those (plus the others not named by you) add up into the hundreds of thousands if not the millions. Nice way to show us how many microorganisms you can name. I hope you have more than a few millions of dollars to pay for all those tests.
Excellent video! I'm glad you are taking science and debunking some of the folklore.!
naturebc I am very glad you enjoyed the video !
@Alberta Urban Garden Simple Organic and Sustainable Many gardeners remove chlorine for a different reason than what was stated. I was taught that filtering out as many adulterants as possible (including chlorine) will lower the PPM and allow higher nutrient absorption. If the PPM is too high because of the presence of chlorine and minerals, it does not matter how much nutrients are added or available once the water itself has reached saturation ppm levels. Please let me know how you feel about this concept and if you have info on it. This is video was great as are your others. Thank You.
very interesting and the sound is perfect. great job, stephen
Oren Kirschenbaum Thank you my friend. the new track was much more difficult to get right when I faded it as it is much louder than my last one. I am not sure if it is in the sweet spot of not too loud but you can still hear there is a clip.
Using an aerator/bubbler helps speed up the process when wanting to remove chlorine.
Nice video
That is good to know! I am glad you liked the video !
Thank you for the research, Stephen! I have been watering my raised beds through drip irrigation, connected to county water with no issues whatsoever! I do use airstones in my water tanks in the hydroponic greenhouse to get rid of the chlorine. It would be interesting to know what kind of effect it has under hydroponic nutrient conditions, as well as compost tea! Great video! I also like the new intro ; )
Keyplayr61 Greenhouse Hydroponics And Gardens I think hydroponics and compost tea might be a little more touchy it sure would be an interesting to see.
Awesome video. You never cease to amaze me my friend. But I've gotta say I do not like the whole "statistically different" shennenigan. :-)
suburban homestead lol its hard not to use the numbers to make a point ;)
I am glad I could help my friend! I continue to enjoy learning from you and hopefully making my videos just a little more enjoyable to watch!
You are right Colin which is why we used an RPD analysis with a conservatism of 100. This allows us to say something meaningful with only one sample.
It would be much better to have a number of duplicates to narrow it however as with everything I am doing this on my own and am somewhat restricted.
Thanks. I am going to use pond water for my bonsai tree farm
Thank you so much for making this video - this is something I've been wondering for some time now! Much appreciated!!
I am glad I could help Kim :)
