A River Crisis Prompts Rare Coverage
According to rare reports today from Chinese media, an environmental crisis is unfolding along a stretch of the Leishuei River in Hunan province that impacts the prefectural city of Chenzhou (郴州), home to more than four million people. Abnormal concentrations of thallium — a highly toxic, colorless heavy metal that causes organ damage and cancer through water contamination — have reportedly prompted the city to activate a Level IV emergency response, and residents are stockpiling drinking water.
In neighboring Guangdong province, the Southern Metropolis Daily (南方都市报), a commercial newspaper published under the state-run Nanfang Daily Group, splashed the crisis across its front page today, with the headline: “Thallium Abnormality in Hunan’s Leishuei River.”
According to reports from both the Southern Metropolis Daily and Caixin Media, the crisis began nearly a week ago, on March 16, as automatic monitoring stations along a section of the river between the cities of Chenzhou and Hengyang, population 6.6 million, showed abnormal thallium levels, “causing trans-municipal pollution and threatening downstream water safety” (造成跨市污染,威胁下游饮水安全).
Jimu News, an online official outlet from Hubei province, immediately to the north of Hunan, reports that both Chenzhou and Leiyang cities have established emergency command centers to address abnormalities in local water quality in the Leishuei basin. Local officials have insisted that drinking water remains safe in the area impacted by the abnormal readings. However, Shanghai’s The Paper said in a report this afternoon, adding wider context to the breaking story, that abnormal thallium concentrations had been detected in 17 out of 22 drinking water sources along the Xiangjiang River in Hunan province, a separate basin, since 2020 — pointing potentially to wider and more longstanding public health risks.
It was only yesterday that that local government in Chenzhou finally acknowledged publicly through its government website what local officials had been responding to for a week: “Water quality in some sections of the Leishuei basin has shown abnormalities.” This public statement came seven days after automatic monitoring stations first detected abnormal thallium levels on March 16, and six days after Yongxing County activated its Level IV environmental emergency response, the Southern Metropolis Daily reported.
