As of my last knowledge update in October 2021, cities in Texas such as Houston, Dallas, and Austin have been reported to still have some lead pipes in their water infrastructure. However, the extent and specific locations of lead pipes can vary, and many municipalities are actively working to replace them. For the most current information, it would be best to check local water utility reports or recent studies on water infrastructure.
Lead gets into the water system though old pipes. Older pipes were made of lead. Cities have been replacing them slowly. Older, larger cities such as New York are most at greatest risk because of the large amount of pipes to replace.
Lead pipes were banned in 1969 because lead is poisonous, especially for the vulnerable (children, pregnant women and the elderly). But, many pre-1970s homes will still have lead pipes today and they have been used in the UK for drinking water for almost 2000 years. The lead content in water is significantly reduced by calcium deposits etc on the inside of pipes but many home owners prefer to replace lead with copper pipes when renovating.
Yes and it still widely used even today
Lead is poisonous if it enters the body, so Water pipes are made from other material now instead of lead. It's not as bad as people make out though if you still have some lead pipes, they are not as unsafe as some people believe.
The lead will leach into the water and give you lead poisoning.
Iron replaced lead in water pipes.
I can't think you are talking drinking water pipes because anitfreeze is poisonous. Nor should you have lead pipes or lead solder in drinking water pipes. So either sleeve pipes or heating pipes then. Antifreeze has inhibitors designed to prevent corrosion.

Lead pipes are not considered safe for use in plumbing systems because lead can leach into the water supply, posing health risks such as lead poisoning. It is recommended to replace lead pipes with safer alternatives.
(1) Uisng lead-soldered joints in the pipes or cooling coils (2) getting caught. ;-)
Houses in most modern countries have nor been built with lead pipes for at least 50 years. Older houses should have been re-plumbed
Lead pipes are made by melting lead and pouring it into molds to create the desired pipe shape. The molten lead is typically cast in sections, allowing for the creation of long, straight pipes. Once cooled and solidified, the pipes may undergo additional processes such as trimming or finishing to ensure they meet specifications. Historically, lead pipes were used in plumbing due to lead's malleability and resistance to corrosion, but their use has declined significantly due to health concerns associated with lead exposure.
