  • As this is relevant to my job, here’s the score:

    This process has been coming for a few years now.

    Some old houses had small sections of their “service line”- the pipe between the main and the internal plumbing of the house - made of lead. The amount of lead that leaches into the water depends on the chemistry (the Langelier Index) and the contact time. There is currently a requirement for regular testing to see if water that sits for 8+ hours leaches enough lead (& copper) to be dangerous if someone drinks it for 20 years.

    The difficulty of replacement is that records from before the 60s are spotty and may not note the material of the line. This will require potholing in front of every house to try to determine the material.

    My town was already planning this out, and was starting to get prices from contractors.
