A Zambia Air Force pilot flew his helicopter close enough to the ground to see riverbanks full of dead fish. He was tasked in late February with assessing the environmental damage of a massive spill of concentrated acid and toxic heavy metals from a Chinese-owned copper mine that contaminated the Kafue River, the country’s most important waterway.
“You could see a layer of oil or film over the water,” he told ADF. “It looked a bit white-ish, cream-colored, and we saw a lot of dead fish. We put lime in the water to raise the pH level. It took us about five days.”
Fifty million liters of toxic mining waste poured into the Mwambashi River, a tributary of the Kafue, just outside of the mining town of Chambishi on February 18 when a sub-standard earthen wall of the company’s toxic waste reservoir collapsed at the Sino-Metals Leach copper mine, which is owned by the state-run China Nonferrous Metals Industry Group.
The waste contained concentrated acid, dissolved solids and heavy metals. Investigators have detected signs of pollution more than 100 kilometers downstream on the Kafue.
“A river has been effectively killed,” Luwi Nguluka, director of communications for the Wildlife Crime Prevention organization in Zambia, told ADF. “This acid spill is an ecological disaster. It will take years to truly understand the long-term consequences. River ecosystems will require time to regain balance, and the loss of biodiversity and livelihoods classifies this as an act of ecocide.”
