i need to know info about spring water, not the spring water u get from a water bottle, but from a real spring

Question

i need to know do animals survive better in spring water and some qualitys about it...bc im doing a science project and have to write a report and im using spring water...

and why it keeps killin my tadpoles...its a science project and i need help NOW!! or i will fail =(

Answer 1

A spring is a point where groundwater flows out of the ground, and is thus where the aquifer surface meets the ground surface. Dependent upon the constancy of the water source (rainfall or snowmelt that infiltrates the earth), a spring may be ephemeral (intermittent) or perennial (continuous). Water issuing from an artesian spring rises to a higher elevation than the top of the confined aquifer from which it issues. When water issues from the ground it may form into a pool or flow downhill, in surface streams.

Minerals become dissolved in the water as it moves through the underground rocks. This gives the water flavour and even carbon dioxide bubbles, depending upon the nature of the geology through which it passes. This is why spring water is often bottled and sold as mineral water, although the term is often the subject of deceptive advertising. Springs that contain significant amounts of minerals are sometimes called 'mineral springs'. Springs that contain large amounts of dissolved sodium salts, mostly sodium carbonate, are called 'soda springs'.

Water emanating from karst topography should not be confused with spring water, since part of it is likely to originate from watercourses that may have found its way through the ground from a sinkhole in the surface at a higher altitude. In such cases, it will not have been subjected to as great a degree of ground filtering as spring water, which has continuously passed through a porous aquifer.

Here is a super good link on this:

Good luck!
