came across this... which is kinda interesting... (well, i never tot of it dat way hahaa)
as the world population starts aging at an increasing pace (human geograghy), the pharmaceutical contaminants in sewage and effluents will start rising at a pace which technology in sewage treatment will need to keep up
which is really true isn't it... as we age and become increasing exposed to pollutants (as my mummy will say - fReE RaDiCalsSS), we start consuming more and more medications...
Just compare the panadol usage of our generation with that of our parents'!!!
where previously we have tolerated certain amount of organic contaminant
(because it is of insignificant amounts) in water... we might not be able to do that in the near future...
... we can never finis upgrading a sewage treatment plant...
