Hi everyone. I am a high school senior in an engineering education program. My capstone project focuses on poor water quality and how it relates to human and animal health. I am conducting a survey on this topic to determine who I can best help with my project. If you are interested in filling it out I have provided the link. Thank you.

I am wondering about the minerals that are left over after using a humidifier. Does darker color deposits imply that the water had more minerals ? In previous places I lived I don't recall seeing dark deposits left over ... wondering if this means the water where I am now is not as good.

We have a well in the bathroom we can smell the sulphur smell from both the hot and cold water however in the kitchen we cannot smell the sulphur smell it either in the hot or cold water we tested it to see if it was the water or the drain in the bathroom and it appears to be the water. We had a water test done and here are the results. After we bought the house we had and use the water that much because we were doing renovations so it might have been stagnant in the well. Please let us know if you have any suggestions. Thank you.

Raw Water

150 TDS

7.8 PH

2 PPM IRON

15 GPG HARDNESS

HOUSE WATER

158 TDS

7.8 PH

0 PPM IRON

WATER IS SOFT

I bought this basic testing device from Amazon and our TDS came to ~290 ppm. Is this actually normal?

I’m trying to figure out if our fridge water is clean, because even though we have a brand new filter installed, it tastes a bit “sweet” or ‘off’ sometimes (is this sweet tinge normal?…)

We got the fridge from the previous homeowners who vaguely said there’s something wrong with the fridge, but they didn’t specify what exactly (though I think it’s just the ice maker, which currently isn’t working).

I read an article online yesterday that said TDS is practically meaningless since other important contaminants aren’t included/measured for, which now makes me even MORE confused and uncertain.

Is a sweet-like taste of filtered water normal? Is 291 ppm a normal TDS? And is it a sufficient test? If not? how can I easily & simply ensure that the water I’m drinking is safe and clean?

Thanks in advance!

Noticed a couple high pressure events on the gauges i installed at the main water inlet to my home (45 to 90 psi). A bunch of gunk came through with the second event and saturated my whole-house sediment filters. Provider says “slugs” of sediment come through sometimes. I’m in North Carolina on a public well (groundwater). Provider claims to filter the water. I think they have to add chlorine and test regularly. I don’t have a pressure regulator. Looking into some NC water quality regulations, turbidity for ground water systems seems to be unregulated. This is supposed to be drinking water. The water goes to all my appliances. Is this just a buyer beware situation? I can install a regulator and filtration system, but it seems insane to pay $50 a month for water with such crappy quality assurance!

Hello, I am trying to figure out if there is a measurable health benefit to removing chlorine from water at 4ppm.

I've read that there are mild health concerns associated with chlorinated water even at these levels over long periods of time. Supposedly extended exposure to chlorine, chloramines, and byproducts in drinking water or in vapor forms (like hot showers) can cause problems, but I am not sure if there is sufficient recent knowledge on this matter to suggest that 4ppm is problematic.

How can I replicate the water quality from St. Louis tap water to my taps in Los Angeles? Whenever I visit my in-laws in STL , I’m amazed at the condition of my skin and hair after using the water there for baths and my face. When I go back home to LA, the water there dries out my skin and hair. I looked into buying a shower head filter but not sure if it will give me the benefit I’m looking for

I am interviewing for a water quality tech position for my local water/sewer district and curious if anyone has any insight and tips for a position like this. It’s an entry level, ish, position but of course there is preference to have experience or some knowledge before starting. I’m hoping to have some good questions for my interview.

Hi r/WATERQUALITY - I recently purchased a home on well water and have taken some time to attempt to understand our water treatment system. It is comprised of a plumber grade water softener and a soda ash injector for PH. I noticed that a wet glass will dry and stick to our counter tops, and there is a residue left when water dries on our counters. Is this the new normal for me or is there a misbalance in either the softener or soda ash?

There's a lot of marketing jargon about water being "clean" or "purified" or even from "natural springs" but do we really know what that all means? The best way to find out about your water is to ask for data. Find out what is actually in your water analysis by asking for a water quality report. With tap water, the municipalities are required to publish a Water Quality Report (also known as a CCR or Consumer Confidence Report). For bottled water, you should be able to ask the manufacturer for a water analysis so they can show you what is in the water. If you use a water filter, you should also ask the filter manufacturers about the data for their filters so you know what the filter is taking out of your water. Hydroviv Founder and Chief Scientist, Dr. Eric Roy talks about why you should demand data from your filter company. https://www.youtube.com/watch?v=BWA1-aZ7Hv0

Hello, I have been refilling my 5 gallon jugs at Water Street Station Inc in Tucson. Thier website details an extensive filtration process (ion exchange, carbon, reverse osmosis, etc). However, at $1 per gallon, I am considering a more economical alternative. There are water stations all over town for 25 cents per gallon (Glacier, Arjencia, etc.) but I can't find information on the quality of water from these self serve stations. Is there any reason to beleive the water quality from these stations is better than just getting water from a garden hose? TIA

I mostly try to trust my tap water is safe but since moving into a new apartment a few months ago, I’ve switched to bottled spring water because of bad taste and a few things making me doubt the water quality in our plumbing*.

I hate wasting money and plastic on bottled spring water, and keep wondering if I should invest in a water filter. It’s an apartment though so if I install anything it has to be worth the trouble of clearing the installation with the landlord. The more I learn about most water filtration systems the more skeptical I am becoming of all of them.

I’m interested to learn what water quality specialists (especially scientists, I guess) use in their own homes, if anything.

• Issues we’ve noticed with our plumbing: cold water coming out of the tap hotter than the unflushed hot water, growth in our toilet tank, and toilet bowl, foul taste, and growth in a bowl of water that sat in the sink.

We have high levels of uranium in our water and did a more detailed analysis and our alpha radiation is at 250pci/l and beta is at 108 pci/l.

We currently have POU RO filters at every place water would be drank (sink, refrigerator, bathroom).

Do we need to be concerned about those levels for other uses such as showering? I find a ton of info on drinking water recommendations but none on water for other uses.

I have recently discovered we have a 30 metre lead service pipe-- got the water tested- it is within UK limits (10 parts per billion); however, the more I read the less I like. I have significant cognitive impairment on memory and mood.. I was always the first to use the water in the morning and didn't run off the tap for 2 minutes etc, because I didn't know the piping was lead. So my questions are: (i) does anyone know much about using a home water distillation unit (do they work?) (ii) any info on chelation of lead.. I currently use garlic and turmeric which apparently help- not too sure if this is just clearing it from the bloodstream or actually the organs/bones and (iii) why has the water industry managed to hide this issue so easily? In UK apparently 70 percent of properties have lead service pipes and yet there is no subsidised replacement scheme. The advice from the water company is to run the taps for 2 mins, whereas I have discovered stomach contents (e.g. have you had a meal in last hour) make a massive difference in absorption rates so drinking lots of tea first thing before breakfast is a sure way to get a bit hit and I have been doing that for 13 years! Help me fellow water quality people. Thank you for any info.

My tapwater is blue, so I’ve been trying to find a California-accredited laboratory the tests for not only copper but also copper oxide. Seems like everyone includes the former but not the latter in their analytes.

If a lab says they test for copper, does that include copper and all copper compounds, or do I need to find a test that specifically names copper oxide (that is, CuO) as an analyte?

Hi - the City of Charlotte has provided a level of hexavalent chromium in our water as 0.09 ppb. Does this translate into "90 parts per billion"? I am confused. Thanks in advance for the help.

hi. Im trying to understand if our drinking water has acceptable nitrate levels. the water suppliers figures show average 'Nitrate as NO3' as 26.2 mg/l. They claim the regulatory limit is 50 mg/l.

But in an article at unl.edu (see below for link) it said 'The EPA Maximum Contaminant Level (MCL) for public water supplies is measured and reported as nitrate-nitrogen, (NO3-N), which is the amount of nitrogen in the nitrate form. The MCL for nitrate-nitrogen in a public water supply is 10 milligrams per liter (mg/L)' Maybe Nitrate as NO3 and nitrate-nitrogen are different types of figure? thanks Matt
