g'day joggerman,

seems to be a bit of hype around about roof water usage, the major
contributor will be the sort of cladding you have on your roof, most
have clay tiles or metal so be no problems with that water even for
drinking.

as for what is in the rain well that can be another story, might be
some factors in nearness to industry belching out pollution or major
thoroughfares with their pollution.

i cannot see any problem using rain water collected for vegetables for
one whatever is in rain water for the main settles to the bottom of
teh tank out of harms way, and is any of it realy in a solluable for
to be taken up by plants through the mycorzoria or worms actions?

anoteh with the watering process with vegetables we only ever water
the root zones of plants not over the foliage as wetting the foliage
can cause other issues like encuraging mildews etc.,. also root zone
watering is the most efficient use of water along with mulch to keep
that water from evaporating.

we use rain water some for drinking our tank 22.5k/litre size as
sedimanet in the bottom as did our tanks on our our previous property
we don't routinely get sick.

i would suggest as their may be pollutant matter falling onto you
garden anyway again depending on your proximity to a polluting factor,
that for above ground leaf and fruit crops you simply wash them before
eating them raw. my sugestion also would be anything that may be left
on those above ground crops from your watering would be washed away
with the next shower of rain.
