How much Chlorine / Chloramine in your water

[itiwhetu]

I am interested in finding out how much Chlorine or Chloramine is in your water supply.

It has been suggested that my system only works as the level of Chlorine is so low that it has no impact on the system. That may very well be the case and something I hadn't considered.
So my town supply has 0.8mg/liter at source, delivering 0.5mg/liter at the tap. That seems to be the New Zealand standard.
How does that compare with your water supply, please.

more than 3.75 mg/liter
i think they change the chloramine for chlorine every once in a while but it's still a monster amount

My tap water has a mean average 0.46 mg/l but can be around 0.67 mg/l chlorine.

Also has 30ppm+ of nitrate.
Zero ammonia and zero nitrite thankfully.

That is very close to our supply numbers.

My United Utilities water supply comes from Ennerdale Lake and local ground water sources .
The water supply to this area can vary in hardness from soft to moderately soft. The supply is low in naturally occurring fluoride and is artificially fluoridated.
(Hardness Clarke 3.36)
Chlorine residual is 0.74 in total, with free chlorine being 0.71. (mg/l)
Fluoride is 0.959, and no higher than 0.98mgF/l.

There's a whole bunch of trace elements and metals present.

Nitrate is 5.62 mg/l on average.

Vancouver water is subject to filtration (sediment removal), UV and chlorination at source. Vancouver has three reservoirs in the North Shore Mountains. There are eight secondary disinfection stations throughout the system that increase chlorine as needed. The stations receiving water from Seymour-Capilano filtration plants is targeted to have chlorine at 0.8 mg/l upon leaving the stations. The stations receiving water from the Coquitlam filtration plant is targeted to have chlorine at 1.20 to 1.50 mg/l. This is because the UV is not used at Coquitlam.

Chlorination is now achieved with liquid sodium hypochlorite, which replaced the compressed chlorine gas system in 2017.

Covid-19 Notice: Recognizing that many buildings or businesses have been unoccupied for some time, Metro Vancouver has temporarily increased chlorine levels to assist with flushing stagnant water and introducing fresh chlorinated water into premises plumbing. This is a precautionary measure in accordance with guidance from the Canadian Water and Wastewater Association (CWWA).

The tap water in Perth, Western Australia, used to have 7.5 chlorine. The safe recommended level is 2. Not sure if results are in ppm or something else. I just know the WA Water Corporation adds some crap and way too much chlorine to our tap water.

I think you will find that is ppm. Those figures are inline with other commonwealth countries. It just looks like America goes way over board.

I'm fortunate - although I've had my Nitrate Fight I have untreated well water so I don't need/use a conditioner (although I have Seachem Safe on hand in the event of an ammonia spike).

I'm curious if you know or even have the ability to know, what levels of metals, etc.. are in your well water?
Obviously, from your posts, you have healthy fish, but I was wondering about the basic randomness of your country's well water.

Here in Blighty, for a wide variety of reasons, my water supplier can give me very, very extensive breakdown of all of the various elements present in my water supply.
Would I be right in guessing that you don't have access to that degree of info?

I don't know without paying for extensive water testing. I can say that dozens or maybe hundreds of homes get their drinking water from this same water table so I doubt there are any issues of alarm for aquarium use.

Interesting.
I'm sure that your water is fine, but I would still be uncomfortable with the not-knowing
I once lived in an area where 100% of the water was from a deep 'bore hole'...a well, as it were. Even so, the water company responsible was able to provide a full breakdown of the water chemistry. There then came a point when the water broke some standard and the bore hole was closed down.

For yourself and your neighbours, you'd only know something was wrong when your hair fell out, or something.

Well if the neighbors go bald or my fish get hairy, I'll get a little concerned.
As for us, we only drink bottled water.

I have no chlorine in my water. We have a private well, and when they came out to do maintenance several months ago they said they stopped treating it with chlorine because of the pets. I use dechlorinator, but the times I have forgotten there have been no negative effects (cause there’s no chlorine)
