Also, because the source of lead and copper is the customer plumbing, lead and copper sampling is specified to be first draw.. Most other water samples are taken by the water supplier's personnel.Trained personnel using consistent procedures generally yield more reliable data.lthough lead is a known poison, the mechanical and chemical characteristics of the metal continue to keep lead as an important component in many products. In water supply, lead's durability and workability selected it for use as water pipes. Lead alloys (bronze, brass) are used for plumbing fittings.
