As reported in the journal Environmental Research, scientists at Bangor University in Wales collected water from the Whitelake River in Somerset following the UK’s Glastonbury Festival 2019 and found worrying levels of both MDMA and cocaine. The researchers tested the river upstream and downstream of the festival site in the weeks before, during, and after the festival. Traces of the drugs were found to be significantly highest during the weekend after the festival in the Whitelake site, downstream of the festival.
MDMA was detected at “environmentally damaging levels,” according to the paper, while levels of cocaine were high enough to impact the local population of European eel, a dwindling species that’s critically endangered and at high risk of extinction. Unfortunately for the eels, cocaine doesn’t provide much of a buzz. Instead, as previous studies have shown, it can result in muscle damage and disrupts their complex lifecycle.
Scientists from Taiwan spotted a spike in the levels of a range of contaminants such as such as ecstasy and ketamine in rivers that flowed in Kenting National Park – home to the annual Spring Scream event.
The experts said that not only does this highlight drug abuse at the concert, but that the drugs may also be having an effect on aquatic life in the region.
Wastewater treatment plants are not set up to remove them efficiently, so they often end up in soil and water. The scientists conclude that drug abuse and its environmental effects are a growing concern.
The findings are published in the ACS journal Environmental Science and Technology.
In a separate study, tests on water collected from indoor swimming pools in the US revealed evidence that everyday pharmaceuticals, such as makeup, could be reacting in a harmful way with the chlorine in the pool.
The analysis found traces of chemicals typically found in skin care products, insect repellent and flame retardants, all of which have the potential to be ingested by swimmers. Previous research has shown that elements of urine including urea, uric acid, and amino acids, interact with chlorine to produce potentially hazardous disinfection by-products in swimming pools.
