1. Lead gets into water by leaching as old pipes corrode.

  • Industrial waste first go through the water treatment process in order to release the the waste into nearby water bodies.
  • There is a permissible limit of lead and other components set by the concerned authority to discharge the industrial waste water. Hence it is unlikely to get lead into water from this source.
  • Detergents do not contain lead.
  • Main cause is attributed to the corrosion of lead that was already present in pipes and fittings.
