Why is spring water considered safe to drink?

107 viewsBiologyOther

So, the spring water comes from an underground layer of water, formed from different materials (gravel, sand, silt, rocks)
” Spring water has a natural filtration process through bedrock, which is why springs look clean and pure when it rises to the surface of the Earth” – how? just how? I can understand a modern filter, where the water is getting thought a carbon filter and gets cleaner. But how do the rocks purify the water? How does the water that comes to the surface not contain traces of sand & other stuff?
Thank you,

Carbon filters do the same thing as rock and silt, they just do it more efficiently so it doesn’t have to pass through as much. 

This is also why large-ish sand filters work well for pools.

Now, it won’t take long after the mouth of the spring for contaminants to start being re-introduced and anything marketed as “spring water” will usually have gone through additional chemcial treatment and/or filtering, but after passing through a large amount of sediment at the source it’s about as clean as anything you’ll find out and about naturally or from your filter pitcher or life straw.

Well, it’s basically the same principle as the carbon filter. The surface of the rocks/sand is coarse, so dirt particles will get trapped in small nooks while the water is pushed through the layer. Your carbon filter does nothing else except for having an extra coarse surface so you don’t need a 10 ft tall filter

Does anybody know if you can get H Pylori from spring water?

no water in the wild should be considered safe to drink.

contamination can happen anywhere upstream, you can’t see bacteria.
