The city of Wuxi, in east China’s Jiangsu province, was hit by a serious ecological disaster [on 28 May 2007]. A large bloom of blue-green algae in Taihu Lake caused water quality to deteriorate severely. Despite the local water department’s attempts at mitigating the crisis, the water supply to a great number of households was contaminated, the water becoming putrid and very unpleasant to drink. [...] Taihu Lake has suffered from low water levels this year, and the weather has been hot – with little rain -- all of which will have contributed to the algae bloom. However, the local government announced that, “the water quality problem is in no way caused by manufacturing or any other human activity,” when in fact there were local factors causing the algae bloom. The serious eutrophication of Taihu Lake was caused by the great volume of pollutants discharged into the water .
