My understanding is that more recent inspections were simply not required - they are a matter of state law.

I would expect some SDWA (Safe Drinking Water Act) suits to be filed - that is a federal law (somewhat ironically, it was pushed into enactment by a Republican Congressman; his district was in long Island and rich housewives were a major constituency - they were concerned about their children).

What it all says to me is that a little care and trouble early on could have prevented a catastrophe later.
