Rivers, wildlife and raw sewage
Cocaine pollution in rivers and lakes may disrupt behaviour of salmon, study finds
"Traces of cocaine that pollute rivers and lakes may accumulate in the brains of salmon and disrupt their behaviour, according to researchers who warn of unknown consequences for fish populations."
“Better wastewater management, particularly reduced raw sewage discharges, could help lower any risks to wildlife and their ecosystems."
"Existing wastewater treatment efficiently removes many illicit drugs, including cocaine and benzoylecgonine, but a main source in waterways is raw sewage that can come from storm overflows and misconnects in household plumbing."
