For some background, I currently go to school in Chicago and my university does not have filters in their water bottle fill stations. I fill my water bottle usually 1-2 times a day from these stations + am in a 1920s apartment that most likely has bad tap water quality. I'm looking for advice from those who have used/are using a filtered water bottle as an edc and would like to know your opinion on if it is worth it price wise with filter refills. My main concerns are lead, pfas/pfos, and other endocrine disruptors. I've only looked into life straw, larq, and grayl and want to get some opinions prior to putting more time into research, thanks :)

The highest rated I can find are NSF 42 inline refrigerator water filters. I'm looking for a filter that can remove lead in this format.

I'm open to any recommendations. Thanks.

Guys I was talking with my friends about those P&G water purifying sachets and someone mentioned downsides. Now I'm curious about what they are, please help me out!

I moved to India from the UK and have come across what seem to be many fake solutions for wastewater treatment here. The first one is something that is called "bioenzymes" manufactured by fermenting citrus fruit peels with sugar and sometimes added yeast. They also sometimes add rock phosphate when they are to be used on soil. It is claimed that this can treat water, remdiate landfill waste, purify air, act as a soil fertiliser/conditioner and also be a cosmetic cleanser. It is claimed that this solution is actually a mix of bacteria and enzymes, hence the name "bioenzymes". It seems to be based on similar claims made by the people who sell EM solution from Japan. It is often referred to simply as bacteria, bacterial cultures or cultures or microbes. It is widely used across India and is added to sewage filled drains and lakes and millions of dollars are spent on it. Also seems to be promoted in Indonesia. The recipe to make "bioenzymes" seems to be identical to making homebrew. Anyone else come across this? Seems to have no scientific basis and would actually result in polluting lakes and rivers more.

New poster here and new to the sub.

I have moved around quite a bit with my family and now we are Las Vegas where the water is just horrible. Typically it’s good enough to be fine without a filter/softener. I just had a salesman come by and quote us almost 10k and I just about dropped over dead.

What does everyone recommend? I am a contractor so I can install just about anything myself. The plumbing and drain is already there. Just need a rec at this point.

I know water tastes different depending on what's in it -- well water, city water, bottled water, etc. If you find yourself going "holy crap I love THIS particular water" how do you go about trying to find out why? Even if I got a print up of my city water, for example, what about it's contents is giving me clues as to why I like it? What about different bottled waters??

I guess what makes up the various "tastes" of waters and how do you hone in on ones that you will like more than others ?

For an example: I live in a WI city that just got an award for their water being one of the best tasting in the state (I agree it's amazing) but I love Core hydration water above all others. And I don't know why.

I’m a student in college needing some help with a assignment. I’m meant to ask these questions to people who know the water policies in California but all the water companies I contacted didn’t respond and the deadline is coming up so I’m kinda desperate. If anyone here knows about CA water management and is willing to answer some general questions about it please help me out. I just need to show I asked the questions and got responses from someone.

Here’s a Google form I made

Edit: thanks to all that responded it was very helpful

Hi everyone, Sorry if this is not the right place to post I wasn’t sure where would be best. I filled up my water bottle for work before leaving the house today and now I’m realizing it smells and tastes fishy? The bottle is clean, I threw it in the dish washer last night. I use a brita to filter our tap water, which is where the water is coming from. Is my brita the problem or is it our actual water source? I haven’t asked any neighbours yet and I haven’t checked the taps as I’m still at work, just wondering if anyone has experienced this or knows why it might be happening? Thanks for any advice or tips!

Hi all. I bought my first water distiller to support my humidifier. It's a Waterwise unit, so not some cheapo thing from Amazon. The distilling itself seems fine, but there's a smell that comes out of the fan that slowly fills the whole house. My nose is probably more sensitive than most, but clearly something is going on. It's kind of like how a new heater smells when you first turn it on, but not quite the same. I even tried it with filtered water (from a ClearlyFiltered pitcher - not some Brita filter) and the smell is still there.

Has anyone experienced this with distillers before? The manufacturer claimed it's because the device is new, but I'm not buying it since I'm almost 10 cycles in at this point.

I used wilko universal for years in my jug, water tasted great. Just bought a set of 3 universal filters and the water tastes like tap water. It filters through in a few mins which makes me suspicious as my wilko took 10m. Anyone had a similar problem? Or can recommend an alternative system.

That the water i drink is the most hydrating? Some waters leave you drier than before so what s the water that you can drink least of and feel most hydrated?

It doesn’t happen all the time but sometimes (usually at home) i have a regular wet mouth but then after i drink water, my mouth actually gets drier. Why does this happen? Does it have something to do with my water filter? How can i assure i get the most hydrating water i can?

Hello,

I'm currently a biotech/UX Design graduate student who wants to focus on working with artificial biological spaces. I'm conducting research regarding a hypothetical device that monitors water quality and was wondering if anyone here would be interested/willing to take the survey. You can find it here.

Thanks!

Recently had to move out of my house and am now renting. What’s the best water filtration system to use for someone who can’t install directly under the sink? Is it a RO tabletop system or maybe a Britta filter pitcher? I’m not to sure what the best option is for renters and would love to hear from anyone out there in a similar situation. Thanks!

Hi I'm a college student in EU looking for a good reverse osmosis filter - preferebly a mobile one (filter pitcher/jug) that doesn't need installment. What the best version I can get in Europe that won't cost me a fortune?

Topic: Artificial Ground Water Recharge

Undergraduate
Civil engineering
Engineering Hydrology
Ground water

A research paper on the topic mentioned

We are given the topic, artificial ground water recharge, to do research on.

I would like suggestions on textbooks (mainly), and if anything else that is a source (websites, this comes to mind) of information.

I have used Google search, GOogle Scholar, Sci-Hub. These are open-source and free. However, I would like some suggestions from other students

Open to questions for clarification

Fluoride & Heavy Metals or Atrizine and Pharmaceutical chemicals?
I have a gravity fed filter at my home and I'm unsure if I should buy the
- Doulton Ultra Fluoride which removes fluoride and heavy metals or
- the Ultra Sterasyl which removes atrazine and pharmaceutical chemicals.

or is there a filter out there that does both I can use in my apartment?

Your adivice on this would be extremely valued.

Hi, we have a dehumidifier in our basement, it is a cement room that gets groundwater and rain water leaking in. The walls have a history of mold. While we work to solve this issue (likely by tearing out and rebuilding), we are getting up to 1 gallon of water a day out of the dehumidier. It seems a shame just to keep pouring it down the sink. But, I know it is not safe to drink.

Has anyone successfully reclaimed and reused dehumidifier water for any useful purpose? Right now the think I can think of is watering plants, but we have very few indoor plants, and the season where we get the most dehumidifier water (western Oregon, rains every season but summer) is the one where the outside plants can least benefit from additional water.

Thanks in advance.

I recently purchased the Bluevua RO100ROPOT-Lite and was initially impressed by its sleek design. However, I quickly noticed something alarming.

The internal TDS meter on the machine reads 3 ppm, but when I tested the water myself, it measured 30 ppm. After some research, I found a blog post from the manufacturer explaining this phenomenon, which they referred to as TDS creep. While I understand that TDS creep is common in RO systems, the extent in this machine seems extreme. After sitting idle for just an hour, the first 50ml of water had a TDS of 100 ppm, despite my raw water only being 160 ppm.

To investigate further, I conducted an experiment. I fed the system filtered water with a TDS of 6 ppm and flushed the system thoroughly until the output water also measured 6 ppm, effectively eliminating any residual TDS creep from the previous water. After letting the machine sit idle for 1 hour, the TDS of the first water produced measured 20 ppm. After 3 hours, the TDS rose to 30 ppm.

How is this possible? Am I missing something? How can filtered water with an initial TDS of 6 ppm end up with a higher TDS after passing through the RO system? I haven’t added any ions back into the water. Interestingly, if I allow the system to filter over 300ml, the TDS gradually drops back to 6 ppm. Initially, I attributed this to TDS creep, but now I’m not so sure. This behavior is confusing and concerning. Can anyone explain what might be happening?

Is this just some weirdly TDS creep or internally their filter is leaking materials? This "TDS creep" thing seems very common in this machine as I saw several amazon reviews about it.

edit: what is worse, my 6ppm input water is now 90 ppm after filtering!! where are the icons from????? is the filter leaking??

Just came across this brand and curious to see what the consensus is.

It looks like a new brand so I’m immediately Skeptical, but it looks like they have legit certifications for their water filter, which goes along way IMHO.
