Yes. They were installed many decades ago and haven't been replaced because a) it would be extremely expensive to do so and b) there are additives which AIUI prevent or at least significantly reduce leaching. I'd be shocked if the EPA's cost estimates turns out to even be within an order of magnitude off the actual cost. Maybe they're just measuring the cost to utilities for the parts not on private property. |

Hard water (high in calcium and magnesium) can form a scale on the inside of copper pipes. In a way this acts as a protective layer, as the water doesn't actually come into contact with the copper.
