Pete Buttigieg forced to explain that lead is poisonous to obtuse Republican

Drinking lead can damage people's brains, but Kansas Attorney General Kris Kobach opposes a plan to remove lead water pipes.

In their letter, the attorneys general wrote, “[The plan] sets an almost impossible timeline, will cost billions and will infringe on the rights of the States and their residents – all for benefits that may be entirely speculative.”

Kobach repeated this nearly verbatim in a March 7 post on X (formerly Twitter).

Buttigieg responded by writing, “The benefit of not being lead poisoned is not speculative. It is enormous. And because lead poisoning leads to irreversible cognitive harm, massive economic loss, and even higher crime rates, this work represents one of the best returns on public investment ever observed.”

  • As an actual water service professional, I kind of get it. If you control pH and add corrosion inhibitors like orthophosphate, lead pipe are not a problem. Flint fiscal managers decided to skip this to save money.

    Unfortunately the plan is a largely unfounded mandate ($15B won’t even cover 10% of lead lines) with a timeline that will further jack up the price due to everyone competing for materials and contractors.

    The vast majority of lead poisoning comes from old paint, not lead water pipes (and leaded gasoline before that … or now if you live downwind from a general aviation airport as piston aircraft STILL use leaded gas. Yet we won’t ban that ‘cause rich people own those planes).

    Not that it isn’t good to remove lead. It’s just the aggressive timeline. It would be smarter to have a longer timeline where it is paired with replacing the main as well, as it is a smaller marginal cost to do both at the same time. The corrosion control can buy us plenty of time. I personally have a lead connection and a state licensed lab detected zero lead in my water.

    But to phrase it as a state’s rights issue and claim the benefits are speculative is stupid.

    • As an actual aviation professional, I'm going to object to "waterworks made of lead pipes: too expensive to fix. 100LL aviation gasoline: Rich people refuse to change."

      First of all, rich people own jets, which don't burn leaded gasoline.

      Aircraft tend to last longer in service than cars do; airplanes are expensive machines. You'll also find that they don't change very quickly because certifying aircraft components such as engines is a very expensive thing to do. Plus, YOU go get an insurance company to cover a new type of aircraft they don't already have accident statistics for.

      But, things are happening. So lemme tell ya what has, is, and will be done to reduce and eliminate leaded gasoline from our skies:

      1. The Light Sport rule. in 2004 new certification standards for aircraft, pilots and repairmen were created which opened up the small end of general aviation. We basically didn't have anything that resembled Europe's "ultralight" rules. USA's Ultralight rules (FAR part 103) more closely resembled Europe's "Microlight" rules. The vast majority of light sport aircraft are powered by Rotax 900-series engines, or Jabiru or the occasional Continental O-200, all of which can run on unleaded automotive gasoline. Every single hour of instruction I've given to a student has been on unleaded gasoline. There's a proposal right now to expand the Light Sport rule that will do anything from increase the scope of what can be certified as a Light Sport Aircraft, and to open their operating limitations. For instance right now as I type this it is illegal to operate a Light Sport Aircraft for compensation or hire except to provide flight training. They're looking to open them up to things like aerial photography, pipeline patrol etc. which would not only allow these operations to be performed on unleaded gasoline, but less gasoline overall. A Cessna 172 burns between 6 and 8 gallons of 100LL per hour, a Flight Design CT burns between 2.5 and 5 gallons of premium MOGAS per hour. Every operation that can switch to a Light Sport Aircraft can reduce their carbon footprint and eliminate their lead footprint.
      2. Diesel engines. I've seen both Cessna and Diamond install turbo-diesels based on some Mercedes-Benz engine, intending to run these on Jet-A fuel which is and always has been unleaded. It's been slow going though; Diamond only offers this on their Twinstar model (and they had some issues with it for awhile; there were some made with Lycoming gasoline engines) and Cessna canceled theirs.
      3. The EAGLE initiative has set a goal to Eliminate Aviation Gasoline Lead Emissions by 2030 by finding a fuel acceptable to replace 100LL in service. This is non-trivial, the testing on all the various engines in service on some surprisingly old aircraft, not only their power plants but the fuel systems as a whole is significant. Many airplanes can't tolerate ethanol as a fuel additive because it will react with sealants used in the tanks and lines, for instance.
  • From what I have heard the inside of old lead water pipes is usually covered in several layers of calcium carbonate, at least in areas with hard water, these layers prevent the water from getting in contact with the lead. So if you live in an old house with lead pipes you do not need to panic. New lead pipes that lack this calcium carbonate layer are what is in fact dangerous to health and therefore should not be installed anymore.

    Edit: Downvotes for stating facts that do not fit the popular narrative, really? Reddit moment ...
