This is only one of many polutantant of the water supply.
For years communities downstream of farmlands, have been
injesting the excess of growth hormones and fertiliser that
gets washed off the fields into the rivers. While the chemical
companies give a recommended safe usage, many farmers
under economic pressure use exccess amounts to ensure a
good crop.
I have been involved in a govenment study for most of my life
that is now suggesting I may be suffering from the effects of
some of the chemicals used in the farming area where I grew
up in.
