This story was so unusual and we believe has such political ramifications,
we wished to put it here even though it may not pertain to the normal
drinking water stories we cover. It turns out that large amounts
of synthetic estrogen used in birth control pills and hormone therapy
are finding their way into water systems. The hormones are excreted
from women’s bodies, pass unaltered through wastewater treatment
plants, and then enter surface water systems. Studies now are
beginning to show that even small concentrations of parts per trillion
are enough to alter the natural hormonal functions of aquatic organisms.
In Europe, male fish downstream of wastewater treatment plants are
developing female characteristics, and losing male traits. Testing
has shown that not only are male fish producing female eggs yoke
protein, but they have also been found to be producing eggs in their
testes. Female fish also are effected by producing eggs at the wrong
time of year.
How will environment be affected long term? The Canadian Department
of Fisheries is currently doing an in-depth study of the effects
in aquatic ecosystems. Preliminary results are beginning to support
that hormone contamination indeed is causing the feminization of
male fish. The study also is looking at how hormones are affecting
invertabrates and frogs.
