Copper not good for underground and too expensive, anyway. Galvanized second choice but again is pretty expensive these days

A few months back we had a slight leak right where the main supply
pipe comes through the basement wall and into the meter. Called the
plumber -- who had to call the municipality and get the water turned
off at the curb -- and found out that the pipe was plastic --
polyethylene? They replaced about six feet of it with copper.

That's interesting. Do you mean buried within the earth? Some soils (sadly at the moment I can't recall what types can cause rapid pitting of copper pipes). I recall visiting a large housing estate some 25 years ago where there was a high unaccounted loss of water on the distribution system. The whole estate (about 10 years old) had been serviced by copper pipework which was riddled with pinhole corrosion of the copper. The complete estate had to be resupplied - with polypipe though I cannot recall the type of plastic now.


Yes, buried within the earth. Somewhat sandy soil, but I have no idea of the pH.
