"Bath" England, which is a small town that is nearly a big city, on the head of the seven estuary, has "specifically good" bathing water, hence the name, "Bath", it was the Romans that made the town important.
The water is still there.
Its not a trademark thing when you are testing specific waters from a geochemical area.?..
What difference the water from a natural warm spring against say Mud.
Are there other areas of specific scientific interest in this natural spring thing...
If fact, lets go opposite of dirty, clean water, how clean is it, and do specific spring waters do anything against the usual corporation pop tap water.
On to water filters...
I use one in my own home, activated charcoal, it "Helps" in some small way, I aint sure what we collect in it, but it does work in filtering the water.
This is just one tap in the kitchen that supplies all our drinking water.
Why?.
How do they work, if indeed at all, and what do they do, and where do you need them more than others.
[..I am thinking more of the show, because I already know what how when and how often about filters being somewhat of a time served apprentice on water filters being I use a hefty on one my pond...]
Investigating a used water filter may fit the brief quite well... just what can you see when you cut a used one open?..
If you want real dirty and messy, I can mail you the pre-filter strainer contents of my pond?..
Or just ask anyone local who has a pond, I aint sure fish "waste" is not hazardous in transport?.. do the security at airports want to search through fish "poo"?...
And Tap water... just how do they prepare it for use?.
[..again, I have "been there", I have studied commercial tap water, and how clean is clean,]
I suggest the team get down and dirty in seeing just how water is made clean for use in taps.

Water filters might be an interesting subject to look at. Spring waters and hot springs less so, or more problematic due to cost and location.
Water treatment seems more suitable for other shows, and also runs into the problem of the specific ways of cleaning it and the standard of water quality varying between states. There are also questions about it being viewed as a political myth, since at least one place in the US currently has contaminated water (it was a big story over there) and the US Government recently removing Federal laws regarding the quality of water stored in reserves.

Spring water, you can collect "Samples" from commercially sold bottled water?...
You just need to namer location of the spring, not the brand?...
And a certain naive phrench brand is disgusting in comparison... you just need to name it as a "popuar brand from france"

The water in Bath comes from one particular pool that still bubbles up water on the site to this day, it's the only source and measures only 20x80 metres. www.dorsetgeologistsassociation.com/RWG/hotsprings/2007_Hot_springs.pdfIt is all controlled by the one organisation, Bath council under a Royal Charter and would fall under product testing in that case. They might allow it though if asked. Other larger hot spring areas might have different sources that could be used. Unfortunately in this country anyway if you know the source you can probably find out the brand I sure the same is true in other countries, due to the need to trace back where drinking water is sourced. Oh and if you ever do go to the City of Bath with its Cathedral. Georgian buildings etc. don't put your fingers in the Roman Baths after 2000 years they are infested with bacteria that will do unpleasant things to your skin. |

I would almost expect anyplace the got a sample from would want to keep the samples anonymous. |

There are a number of public springs you can collect samples from is you so wish.
Buxton Spring water has a very public "fountain", in that its a public access place you can fill your boots with if that is your wish.
I suspect that there are many other public springs that have been "Tested" by an environmental 'elf, and allowed to stay public, that you can if you so wish collect water from.
If you have the time, you can always trace water sources back to source, say public rivers etc?.
"Product testing"....
Not to name names, but you could test a number of commercial filters by "Type".
That would get around product testing.
I am considering this as sort of the idea they used to test certain "Fuel boosters" by type rather than product name?..
There are micro screens, activated charcoal, chemical, etc, test a batch of "safe" filters that have been passed by that environmental 'elf organisation as safe to use, and see which does the best work and for how long.
Test them all on the same "safe" tap water batch, some signed off for public tap water use, and then test them again on an "Unsafe" water batch sourced from say dipping a 50 gallon drum in a public river.
Not an overly polluted river, just one that you would expect to see wildlife drinking from?..
Send off for examination by a reputable testing facility with a control of untreated water, and compare results.
Run them for maybe two days or two weeks solid at max capacity, then break open the filter and compare inside with an unused one?.
You may have to set up a remote testing facility 'stream side' for the untreated river water?.. just set it running and let it go for a week.

The legally in the UK Spring water comes from underground there is no river to trace it back to, they take the source water from where it seeps from the rock into their bottling plant, or nowadays use boreholes that go down into the aquifer they are tapping.
The companies own the rights to these and in many cases there is no right for the public to take samples, the various bodies responsible for public health can yes but not the general public.
There may be a few places such as Buxton were there is a publicly available source that's not often the case.
You could test public springs, yes there's one not too far from me, but the water companies would say it's not the same as "their" water.

Spring water is most likely impractical to look at. Even discounting legal aspects, the fact is that they don't have the time, money or resources to get a significant number of samples. Nor do I think it would be considered 'cost effective' due to the nature of the testing requiring the use of a lab (hence sidelining the hosts) and not giving much if anything in the way of visual results.
Filters might be a more interesting and practical thing to look at, especially since they might be able to create water that contains higher than normal levels of contaminants that could be quickly and easily tested in shop with simple visual chemical tests. Maybe add in a part where they see if they could make an 'ultimate' filter or alternate uses for water filters.

(as in, it probably wouldn't get gasoline out of water, but it is rated to defeat Montezuma's Revenge.) |
