How can water pollution be solved?

Flexi Says:
Reclamation occurs when people attempt to restore an altered property, such as one that has been mined, to its previous state. The reclamation of a lake and rivers is crucial to protect the fresh water from further pollution and reclaim it back to its natural state. Reclamation have major impacts on the structure and functioning of lake and aquatic ecosystems. Most contaminants enter the water because of humans. Surface water (river or lake) can be exposed to and contaminated by acid rain, storm water runoff, pesticide runoff, and industrial waste. This water is cleaned somewhat by exposure to sunlight, aeration, and microorganisms in the water. For long-term restoration, it is essential to control the source of the problem.
