Industries polluting Taihu Lake in Jiangsu, China

It's not only climate or rainfall change; industries are also responsible for contamination of water bodies and death of aquatic life.


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 [1].

Do you consider this as a success?Not Sure
Why? Explain briefly.Four years later, a campaign to restore Taihu is showing results. [...] Restoring Taihu to a truly healthy state, however, will be a steeper challenge. [...] The central government, through its Ministry of Environmental Protection, plans to allot $155 million over the next 5 years to clean up Taihu. The ministry is now drafting a work plan. But the challenge, says Qin, will be to pinpoint sources of nitrogen and phosphorous to better stem their flow into the lake [3].
