I don't see that as a problem knowing what dogs will sometimes eat.
Heck, they are even known to grab a snack from kitties litter box
without getting sick.(although it makes me sick thinking about it)

Someone I know just tore out their preformed pond because they
thought their
dog got sick from drinking the water (I'm not complaining since I
now have a
new pond...I just have to decide where to put it and start
digging). Does
anyone know if this is possible? DK

Biologically filtered pond water much better than what animals
usually get.

It would be interesting to measure the nitrate level and compare to
water quality specs for potable water. I don't know what the
symptoms
of nitrate ingestion are...
