Ticking time bombs - What risk do abandoned oil and gas wells pose? | DW Documentary

Video Description

The extraction of gas and oil poses a greater threat than previously thought. Leaks at disused drilling sites can trigger an environmental disaster at any time. If toxic substances escape, human lives are at risk. Oil companies invest little in securing the former boreholes. Environmental activists are among the few on the lookout for this invisible danger: Of the 20 to 30 million former drilling sites worldwide, only a few are regularly and carefully monitored. From the North Sea to the Alsace region in France to the USA, abandoned extraction sites can be silently causing significant harm to both the environment and human health. Take Bradford, USA: Here, several residents fell ill with mysterious symptoms including hair loss and nosebleeds. Eventually, medical doctor Jeffrey Nordella discovered they were all suffering from chronic benzene exposure caused by methane and crude oil. The substances had escaped over a long period of time from a disused borehole. Elsewhere, gas explosions from leaking production facilities cause enormous damage. In many countries, oil and gas companies are legally obliged to seal abandoned wells immediately. However, the implementation and monitoring of these regulations is sporadic. Activists and whistleblowers are constantly trying to draw attention to this abuse. #documentary #dwdocumentary ______ DW Documentary gives you knowledge beyond the headlines.
