I can understand COD and BOD being relevant if you're treating water to a standard for discharge in to an eco system, but what effect does it have on what colour water can you need? Likewise with pH and temperature?

Ah, so now I see where the 'water container' jibe comes from. Are you looking for serious answers or just out for a fight JMPC?

Quote: | as for bacteria needing light to grow . nonsense | I never mentioned bacteria. Algae and/or mould needs light to grow. A steel or black plastic water container will help defeat this.
You also need to use a good water filter or purifier if you are in any doubt about the quality of the water source or if you're storing the water for longer than a couple of weeks.
Place a clear water container in the garden and fill it with rainwater (not tap water which has been chlorinated) then see how many days it takes for it to start to go green.

There's 2 things which you don't want to happen in the water:
- something which will make it taste minging
- something which will make you ill
The two things aren't necessarily the same. Generalisation, but algae will taste bad, but not make you ill; too much bacteria will make you ill. You can get little tablets to add to the water, which kills almost all the bacteria and somewhat (but not completely) neutralises the taste. Black rather than clear containers will reduce algae growth.

Oh dear! that didn't turn out very well.
Needless to say, I cannot **** through a keyhole Fortunately our floor is tiled so the resultant mess was easy to clean up.
But on a more serious note, do the concerns over cleanliness of water container and light resistancy only apply if you are using non chlorinated water? Surely the Chlorinated water will kill harmful stuff when it is put in the container (I'm assuming the container is reasonably clean to start with). And as long as the container is gas tight, the Chlorine will remain in the water while the container is stored full, thus keeping any bugs at bay. This is assuming that you are using Chlorinated tap water and you are confident of the quality of the source; in my instance its mostly from water points on a Caravan site so its mains fed and used within hours. If you're travelling overland, especially in third world, I guess the choice of container may be more critical.

Having owned and used a motorcaravan for a number of years (no longer though), 'fresh' water from a water point on a campsite loses its freshness due to the chlorine after a couple of days, then gradually tastes worse and worse. So, if you're travelling ie spending time with the vehicle and constantly topping up the water containers every few days or so, things are less critical. If you're 'stocking up' on supplies before going away from running water for any longer, then you'll need some kind of purification system (or a strong stomach and not too fussy on taste!)

Whilst we were travelling we used a ceramic water filter, others we were with just put tablets in their jerry cans. I'm glad we went with the filter route, as every so often the filter would clog with silt and debris and we'd have to give it a gentle scrub. One time whilst doing this we found a worm living in the bottom of the filter housing. Nice!

In the last 100years or so, we have become accustomed to ever increasing levels of cleanliness.
The end result is that we cannot tolerate drinking contaminated water, or eating rotten food.
1,000 years ago you would not have had an alternative.
Farmyard animals drink water and eat the grass that they have already urinated and defecated on.
Roger
We used to be able to do the same.

Farmyard animals don't (at least ruminants).......at least they don't eat areas they've defecated on:
Notice that the field is quite well grazed, but tufts of grass remain. This is where cow pats are, and the cows instinctively avoid them. Also, cows won't drink water that tastes funny. Note, they will drink it if its contaminated but doesn't taste funny, so certain bacteria can harm cows. Hence ponds and streams etc in a field of cows are fenced off, to prevent them drinking from them.
Certain other animals do, and have an immune system to cope. For example pigs and chickens. Other animals, eg all rodents, rabbits, actually eat their own poo and effectively it gets a second pass through their digestive system. The reason? Vegetable matter is difficult to digest compared to animals, so herbivores have a much larger digestive tract. (Notice how large a cow is, compared to a lion, for the same approx length of animal). Rodents and rabbits would be severely disadvantaged in the food chain (vulnerable to predators) if they were fatter and digested the food once, not twice.

Cows urinate and defecate onto the grass. Rainwater will wash any poisons into the ground. This will be absorbed by the grass and subsequently eaten by the cows.
The poisons that are washed into the streams will be drunk by the cattle in the farms that are further down the valley.
Years ago it was acceptable for humans to drink water from mountain streams.
This is no longer considered safe.
Our immune system has been depleted to the point that we cannot ingest any thing that has not been cleaned to laboratory standards.
I wonder how far back we would have to go before we found one of our ancestors who could drink sea water and survive?
I assume sea birds can!

No worries, I see what you're saying but cows aren't dirty animals (well, relatively....) and if they're in dirty conditions or nosing through their own dung, then the farmer's not doing his job properly! I could bore you to death with grazing systems and the nitrogen load cattle put onto grassland, but its way too off topic!
But basically yes, animals tend to have a 'naturally resistant' immune system, and that humans have tended to live more and more in concrete jungles, rather than the natural surroundings we all (10,000 years ago) were once in.

May be opening a different can of worms or algae/mould/bacteria.
Why does bottled water come in transparent containers? Is it difference between spring water (naturally filtered??) and rain water/stream water?
Or is it down to the amount of exposure to sunlight?
When travelling I use several water containers and avoid having water from different sources in the drinking water containers. The main water tank is a 70 litre stainless tank and this is used as general purpose water. Drinking water is either in 20l black water bladders or in transparent spring water containers.
One advantage of the water bladders is the minimal amount of space they take up when empty in comparison to a 20 litre jerry can.

Probably because:
1. Its been purified/processed to not have any algae in it
2. Marketing reasons - would be difficult to sell water in an opaque bottle

Simon your " other nasties " bit threw me, i read this as bacteria, which are mostly considered nasty.
Rodger, what are you on man. animals eating their own faeces, ?
As with many subjects on here , there are those who genuienly want to debate, those that listen intently and respond with fact, experience or a theory. perfect.
some just take the **** ( pun fully intended)
the thread has digressed somewgat, but mostly relevant stuff.
for those further interested in the subject i can suggest two books
1. how to **** in the woods
2, Humanure the art of composting human waste.
for further reading. some of you could do with the help.

Terence, let me explain.
The point I made about animals eating the grass on which they have already urinated and defecated on was queried by Paul C yesterday. I answered his query and he replied that he was satisfied.
Did you actually read his query and my response?
Your condescending ways, your hypocritical accusations and your general surly attitude do you no favours.

I think TBF was only trying to be humourous, if we can't have a giggle every now and again, its going to be not so good. Don't take it too personally.
