I wonder what the accuracy of the data is like. And what do you do about damaged pipes? I read that cities lose a lot of water to leaks. Doesn’t that also mean pollutants can get in? And it won’t matter if your pipe is lead or whatever else.
An aside: lead exposure is thought to lead to increase violence. I wonder if Chicago having the most lead pipes is also a contributing cause of their (reputed) crime problem.
