You are correct in your assessment. I would also add the MDEQ because if they were practicing due diligence (their reason for existence) the Flint disaster might have been avoided.
All of my house was galvanized, including the connection pipe under the yard until 10 yr ago. Then all of the hot water has gone to copper with silver solder and the inlet to copper too. Now some PEX (which may be questionable).
The house has old lead paint, but the kids never ate any so they turned out fine. Same with whatever small amounts of asbestos that are present.
