pipes minimize the leaching of chemicals into the water supply?

Leaching of pipes can be a health hazard issue as toxic chemicals can be released into the water. It is certain that leaching is not visibly seen but can dysfunctional our organs making us severely ill. While looking up for plumbing pipes one should also take into consideration whether the metal leaches easily or not?
In the process of leaching, chemicals migrate from pipes into the water. Water can be contaminated by plumbing pipes and fittings and joining materials. Leaching can also occur when materials are corroded, dissolved, diffused, or detached.
