Information on Faecal Coliforms

First of all, let me state that I don't work with water samples.

It has always been my understanding, however, that coliforms can be
present in water without being from humans with the exception of E.
coli.  That is why E. coli (in all its various strains and forms, which
are irrelevant here) is tested for to determine fecal contamination of
water.  I believe species of Enterobacter can occur in nature, but
they're obviously also found in human feces.

Will you environmental micro people say yea or nay to this?  I don't
want to mislead anyone.  I can't comment on point 2 and 3 as I just
don't know.
