Is the water pure from spring, river, and lakes?
In general, no. Most surface water (rivers and lakes) is slightly turbid. The turbidity can originate from different kinds of matter in suspension, such as: fine sand, clay, slime or microorganisms, and colloidal particles that are particles of organic matter from leaf decay, cortexes and other vegetable substances in decomposition.
