Even so, lead still can be found in some metal water taps, interior water pipes, or pipes connecting a house to the main water pipe in the street. Lead found in tap water usually comes from the corrosion of older fixtures or from the solder that connects pipes. When water sits in leaded pipes for several hours, lead can leach into the water supply.

60 million Euros per year. For Vanadium, a very rare soft metal element, the net value in Sweden for this metal is approximately 3 millions/ year with a prize of 280 Euro/kg. However, as the metals in fly ash arent present in metal pieces its not possible to directly recover them using physical methods hence chemical leaching is needed[1]. 2.

Chloramine, Chlorine, Lead and Pipes How Water Treatment

Lead (or any metal) leaching occurs when corrosive water enters an old pipeline and easily reacts with the metal pipes, creating metal ions that enter the water. Chlorine can combine with lead to form an oxide, which acts as a passivation (protective) layer on the inside of the pipes. This protective layer was protecting pipes from corrosive water.
