Here's one that turns the whole "we're fixing the pipes" headline on its head.
Providence, Rhode Island. May 2010. The Providence Water Supply Board announced a plan to replace the city's aging lead water service lines. On paper this is unambiguously good news, fewer lead pipes, less exposure, the kind of infrastructure work anyone would applaud.
Except they were only going to replace half of each line. The part that ran under the public street, yes. The part that ran from the sidewalk to the customer's house, the "homeowner's portion", would stay. Those stretches of old lead pipe, the ones actually connected to the kitchen faucet, would remain in the ground.
The problem with this is not a philosophical one. It is a chemistry one.
When you replace only the public portion and leave the homeowner's portion, you end up with a new copper pipe soldered into old lead pipe. You have also disturbed the old pipe in the process, bending it, cutting it, jostling its biofilm. Both things together spike lead in tap water for weeks afterward. The disturbance knocks loose accumulated lead scale that had been settled on the pipe's interior. The joint between new copper and old lead creates galvanic corrosion, a small electrical current between the two metals that accelerates lead leaching into the water passing through.
The partial replacement made the lead problem worse, not better, for the family in the house.
Emerging EPA research was already showing this. The partial replacement was, in a measurable way, more dangerous than leaving the old pipe alone.
Providence Water was not being evil. They were being practical. The public portion of the line was their legal responsibility; the homeowner's portion wasn't. Working on the homeowner's side required the homeowner's money, or at least their permission, and a lot of homeowners said no or couldn't afford their share. So the utility replaced what it could replace. The result of doing its job by the letter of the law was to hand the customer a worse exposure than they had the day before the truck pulled up.
A local advocate in Providence caught it.
She organized. She publicized. She posted to the lead safety peoples group email list. She forced a public meeting. By September 2010 the Water Supply Board agreed to suspend partial replacements and wait for federal guidance. A small city had gotten its utility to stop, on its own, without federal intervention.
Eight months later the American Academy of Pediatrics wrote directly to the Administrator of the EPA asking her to end partial lead pipe replacements nationally. The AAP letter got forwarded to the same email list and amplified to the few hundred lead safety people on it. A corrosion engineer replied with the underlying chemistry in plain language so anyone could cite it. A pediatrician somewhere read it and showed it to her state senator. The letter moved.
That is how the fix-that-was-making-it-worse eventually slowed down in the United States.
There is no CIA for lead. There is OSHA for your job, EPA for your outdoor air and water, CPSC for your toys, FDA for your food, HUD for your paint in federally subsidized housing, and thirty state and city departments running frontline work, and on this particular issue, the lead safety people on a single email list doing the cross-disciplinary briefing that no single federal office was staffed to do.
Every person in this story was doing an endpoint job. The utility engineer. The water board. The EPA researcher. The advocate, doing what nobody was paying her to do. Primary prevention, the systemic move that says don't do partial replacements in the first place because the science says they're worse, was not in anyone's job description, until an email list and a local protest made it one.
That's what the rest of this book is going to be about.
