Why Is Flint’s Water Still Unsafe? Or Is It?

Can someone help me out? Flint reconnected to the Detroit water system in October, and it was supposed to take a few weeks after that to clean out the pipes. So what happened? I keep seeing pallets of bottled water being delivered to Flint, but shouldn’t the tap water be safe by now? Has it been tested for lead levels in the past month or two? I’ve been trying to check this out, but I can’t seem to find anything definitive.

I feel like I must have missed something. I don’t know how hard a thorough round of testing is, but it sure seems like that would have been a top priority starting in early November. Is it being done?

UPDATE: Here’s the answer:

  • Over time, the lead pipes in Flint built up a protective mineral coating—or scale—that prevented lead from getting into the water.
  • During the 17 months it was used, acidic water from the Flint River corroded away the scale, exposing fresh metal.
  • Even if the water is now good, it’s going to take a while before the scale rebuilds. In the meantime, lead can still leach into the water.

Back in December, the Flint Utilities Director announced that they planned to boost the level of phosphates in the water to aid in rebuilding the scale. They also hired a firm to begin testing of high-risk homes. Normally it can take up to five years for scale to rebuild, but presumably the additional phosphates will reduce this time. Still, it might be quite a while before the water is safe again, which explains the continuing pallets of bottled water.

THE TRUTH...

is the first thing despots go after. An unwavering commitment to it is probably what draws you to Mother Jones' journalism. And as we're seeing in the US and the world around, authoritarians seek to poison the discourse and the way we relate to each other because they can't stand people coming together around a shared sense of the truth—it's a huge threat to them.

Which is also a pretty great way to describe Mother Jones' mission: People coming together around the truth to hold power accountable.

And right now, we need to raise about $400,000 from our online readers over the next two months to hit our annual goal and make good on that mission. Read more about the information war we find ourselves in and how people-powered, independent reporting can and must rise to the challenge—and please support our team's truth-telling journalism with a donation if you can right now.
