I am harvesting rainwater this year, so any fiberglass or tar will be a
problem there as well. Garden is just to the north of the house, so
wind blows residue from roof into garden.
Gotta be as careful as possible and do the best you can.
I'd guess the newer homes contaminate at a higher rate quickly. Then
drop off emissions in time.
Best practice to balance on this stuff is a question I'd like to see
addressed. My home 35 years dealt with the issue in ignorance.
Not much has changed except water use is way reduced.
Intentional. I've a 350 gallon poly tank that I'm hooking to a
downspout. I'll water using a submersible pump from our koi ponds that
are no more. Also have several 55gal pickle barrels that are terra
cotta colored for other downspouts.
Oz on the other hand is harvesting unintentionally.
Strange you mention that! Before putting on gutter covers so I don't
have to clean gutters, it was not unusual to find nice fat earthworms
in the gutter when cleaning. The only explanation I have is, we have
lots of birds and some must have dropped worms in the gutter on the
way to feed the young.
I've found them too!
Last spring several mornings I found twings and leaves and some gunk on
the pickup hood and was a bit puzzled until I caught one of the
resident robins scratching in the gutter and take off with a worm.
If you mean your rain gutters, go ahead.
If you mean the street gutters, do you know what your neighbors dumped
into the street? Do you know what kinds of herbicides might have run
off their front lawns?
