The big, real answer is: it depends on where you live. In the United States, the big turning point was 1986. That’s when Congress amended the Safe Drinking Water Act and basically said, "No more lead pipes for new construction or repairs." If you built a house after 1986, you probably got copper or plastic instead. But here’s the kicker: homes built before that date were happily left alone.
Think of it like your favorite pair of jeans. The company stopped making them in 1995, but you can still wear them. That’s exactly what happened with lead pipes. Millions of homes across America were still sipping water through old lead straws for decades after the ban. Some still are today.
But Wait—What About Flint?
You might remember the name Flint, Michigan from the news. That wasn’t a case of old pipes, really. It was a case of a city switching its water source, and the new water was so corrosive it literally ate away the lead inside the old pipes. Suddenly, a problem that had been quietly sitting underground exploded into a national crisis. It was the wake-up call nobody wanted, like finding out the weird smell in your car is actually a forgotten sandwich from last month—oops.

That event in 2014 pushed cities to stop pretending. Governments started realizing that "invisible" doesn't mean "gone." Today, the fight is all about digging up those old lines, one house at a time.
