Doesn't seem like there's a smoking gun here — TBH I'd be more worried about lead pipes, which still exist and are known to be pretty bad. (And disinfectant byproducts in drinking water like chloroform, which are startling high, have known mechanisms of action that cause cancer when ingested orally, and have minimal if any phaseout plan.)
If we were still using asbestos to build new pipes that might be worth looking into, but since it's already phased out and the studies on harm in drinking water aren't conclusive... It seems like there are better uses of effort to improve health via drinking water changes.
