when did the us stop using lead pipes?
1986
present-day water-supply systems use a network of high-pressure pumps, and pipes in buildings are now made of copper, brass, plastic (particularly cross-linked polyethylene called pex, which is estimated to be used in 60% of single-family homes), or other nontoxic material. due to its toxicity, most cities moved away from lead water-supply piping by the 1920s in the united states, although lead pipes were approved by national plumbing codes into the 1980s, and lead was used in plumbing solder for drinking water until it was banned in 1986. drain and vent lines are made of plastic, steel, cast iron, or lead.

for many centuries, water pipes were made of lead, because of its ease of processing and durability. the use of lead pipes was a cause of health problems due to ignorance of the dangers of lead on the human body, which causes miscarriages and high death rates of newborns. lead pipes, which were installed mostly in the late 1800s in the us, are still common today, much of which are located in the northeast and the midwest. their impact is relatively small due to the fouling of pipes and stone cessation of the evolution of lead in the water; however, lead pipes are still detrimental. most of the lead pipes that exist today are being removed and replaced with the more common material, copper or some type of plastic.
