stuff snipped

While we're on the subject, are normal well-heads open to atmosphere?
in which case, if a local flood covers the well-head, you can expect
a contaminated well? Or are they typically sealed?

Good question. There are lots of "gotchas" to consider - that's one I
hadn't thought of. A friend I know got God-awful sick from giardia (sp?)
that came from a contaminated well. They were seriously ill and it took a
while to recover.
