Serious Is our tap water drinkable? Do we really need to boil first?

[eatshitndie]

sinkieland tap water has never been drinkable. Back to the 70s they have overchlorinated it, and it used to be so bad you could smell the chlorine in it. Then they try to blend sai chwee with the potable water supply until some scientist told them even after many filtrations and treatments, sai chwee was still toxic. Now sai chwee is used for industrial purposes, but too late. sinkies already consumed it. U ever ask yourself why sinkieland got so many cancer cases or not?

sewage water that goes thru’ reverse osmosis filtration system in sillycon valley has been found with a wide range of pharmaceutical compounds that cannot be filtered away. can you imagine the amount of fentanyl residue in the sewage water in california? this is why r.o. water in the bay area is banned from being mixed into water for household faucets and or drinking. it is pumped thru’ a different plumbing system and is still used for industrial washing and watering of pubic parks and large landscapes, including golf courses.

Boiling water is a very expensive way to treat water. If you really want to treat the tap water, use a reverse osmosis system. It will remove all the chemical contaminants that boiling cannot remove. Best is distillation, but RO is where the sweet spot for water treatment is.

r.o. cannot remove a wide range of pharmaceutical compounds.

Flouride europe banned for decades, sinkies still drinking. Brain dmg is not an issue here

flouride is still in use in sillycon valley water treatment plants to minimize dental cavities.

Really? Not doubting you, but aren’t these fairly large organic molecules which will not pass through the membrane? Or is it that the pores in the membranes are still too large?

those that pass thru’ r.o. membranes are made up of chemical compounds with tiny molecular structures, some smaller than the water molecule. some organic compounds pass thru’, and these are usually volatile organic compounds or voc’s. you’ll need multi-staged carbon filters like a solid block activated carbon (sbac) filter to filter out voc’s.

Aren't most pharmaceuticals organic compounds, so based on carbon ring structures that are much, much larger than a water molecule? According to this: https://pubmed.ncbi.nlm.nih.gov/18656225/

RO systems have excellent rejection of pharmaceuticals. I suppose it depends on the quality of the RO membranes used too...

Edit: Yes, the membrane is important. Just found this: https://www.sciencedirect.com/science/article/abs/pii/B9780444626578000100
Use the wrong one, and you don't remove pharmaceuticals.

Double steam distillation is the best, but it's just too expensive for large scale use.

I do think, but not like anal asshole like you. Happy with my answer ? If not happy, you can go fuck yourself with my blessings.

so easily triggered. you must be very stressed. my condolences

3 pharma compounds are especially troublesome for r.o. membranes (% retention in some of the most stringent membranes): acetaminophen (44.8–73%), gemfibrozil (50–70%) and mefenamic acid (30–50%). this is based on research in 2008. some get thru’ some don’t depending on membrane used. it’s better to augment the r.o. system with an sbac filter. r.o. as a standalone solution is not recommended if you truly care about the quality of water that you drink. of course, newer r.o. systems today have better membranes and usually comes with advanced carbon filters and uv as a complete system.

Aha, thanks for the info!

 

[nightsafari]

after purification by distillation, one needs to add 6.9 drops of this to every liter.

haha!! you always got everything figured out long before I got there!

simi si sbac filter?

 

[eatshitndie]

simi si sbac filter?

solid block activated carbon or sibei-ai-ci (ai-tua-liap-nee) filter.

 

[nightsafari]

solid block activated carbon or sibei-ai-ci (ai-tua-liap-nee) filter.

better than 69% efficacy!!

Not to go too far off topic, but the difficulty of removing crap from water is why China is long-term fucked, with 80% or more of its groundwater sources polluted with heavy metals, industrial organic compounds, fertilizer runoff, oils, and also pharmaceutical compounds from farming, etc. Can't even trust the bottled water there.

Yes correct. except that sai chwee was labeled as safe for human consumption and many politicians were drinking it to publicize it. Which is why I said it was never drinkable in the first place. First too much chlorine and now mixed with sai chwee.

Certainly, but after filtering and witnessing the before and after of your filtered tap water, you might not want to anymore.
