To this end, urban groundwater samples were collected in the city of Barcelona and a total of 21drugs were analyzed including cocainics, amphetamine-like compounds, opioids, lysergics and cannabinoids andthe prescribed drugs benzodiazepines. Overall, the highest groundwater concentrations and the largest number ofdetected DAs were found in zones basically recharged by a river that receives large amounts of effluents fromwaste water treatment plants (WWTPs). In contrast, the urbanized areas yielded not only lower concentrationsbut also a much smaller number of drugs, which suggests a local origin. In fact, cocaine and its metabolite weredominant in more prosperous neighbourhoods, whereas the cheaper (MDMA) was the dominant DA in poorerdistricts. Concentrations of DAs estimated mainly from the waste water fraction in groundwater samples wereconsistently higher than the measured ones, suggesting that DAs undergo removal processes in both reducing andoxidizing conditions.
