Radio 4 on drugs in the water supply

17th September 2014, 12:05

Timely programme on BBC Radio 4 last week about drugs entering the ecosystem via STW's.   The issues of endocrine disruptors, hormonal actives and bisexual fish have been known for about twenty years of course, and to an extent this problem is being alleviated by better tertiary treatment.  Apparently the next generation of problems is coming from drugs associated with neurological  illnesses - and that these are in some cases extending the life of some fish species (though what the implications of that are for local ecosystems can only be guessed at).

The programme spoke to mainly academics, rather than anyone actually responsible for running a STW, which was a pity.  Also, while there was reassurance that the trace levels of these drugs was way below likely harm levels to humans, it failed to discuss  how these drugs react with each other in water bodies - and whether this cocktail effect may be the real threat.
