A study last year from Germany’s Free University Berlin found that the psychoactive drugs primidone and phenobarbital were found in drinking water supplies. Oxazepam and others were found in wastewater streams – likely soon to be in the drinking water supplies.
Another study from Spain – this from the Pharmacy Department of the University of Valencia – found numerous pharmaceuticals among the region’s ground water and drinking water supplies. They found 94% of the sediment and 80% of farming soils were polluted with carbamazepine, acetaminophen and others. They also found much of the drinking water supplies, pharmaceuticals were present at levels as high as 112 nanograms per liter. Soils contained lower concentrations, 15 nanograms per liter.
The researchers also pointed out high levels of fluoroquinolones and ibuprofen are threatening fish and otherwise contaminating the environment.
