is there any risk associated with using (diluted) pee in the garden from people (unnknowingly) having some kind of urinary infections, carrying potentially harmful bacterias?
What about the pee of people taking medicines? can this substances build up (as for the antibiotics mentioned in an earlier email)
in plant tissues and be ingested by people?
Thanks for this discussion

Thanks for the dialogue, interest and opinions. I'm afraid that I didn't say
it well enough - Martha's Vineyard is a small island off the coast of Mass.,
USA. The overwhelming majority of sewage is processed by septic systems at
individual homes, no island-wide septic/sewage. "Individual" in my
context is meant to convey an individual household.
I fully agree that Bears do it [right], and humans can also - pee/poop in
the woods. The "cat scratch" is also an elegantly simple way of nature worth
emulating. And, the Orchard Toilet is a good model from this. I'm all for
difusing waste into nature and natural processes - want us all to move
toward that. Also believe fervently, as you do, in moving away from large
quantities of human waste that is collected [and neglected or] handled by
My start on this path is to separate my [individual] urine and use it to
help my comopst along - a very individual-family and natural process - or to
dilute it and use it as fertilizer on our family garden. My plan is to move
away from [or never join] large, industrial processes for anything. I also
plan to read/study further on what is and stays in urine and what is and
stays in poop - both good/bad and what Nature can/does break down to
good/harmless and what it can not.
