I thought I had an electronic book about this topic, but I can't find it in my files, so I'm hoping someone here can point me to it
online. Some things I remember about it are:
Discusses in depth the use of earth to filter
urine, and earth closets;
Relates the account of a wealthy landowner insisting on enclosing the sewers, and the rise of cholera and dysentery in the region;
Tells about the well in a (his?) garden in town that the
local authorities wanted him to fill in, but he tested the
water and it was clean even though there was manure applied in the garden above.
Does this sound familiar to anyone?
