China’s Taihu Lake, which supplies water to 30 million people, could be threatened as swathes of algae have been found in certain parts of the lake.
Media reports that Jiangsu Province has ordered emergency monitoring by provincial, city and county agencies, while workers in Wuxi City have removed 190,000 tons of blue algae and 1 million cubic meters of silt from the lake.
According to Nanjing Institute of Geography and Limnology, satellite monitoring showed blue algae began to appear in the west and south of the lake on April 3, showing that the lake had entered a sensitive period of annual algae outbreaks.” That said, Taihu Lake has seen an algae outbreak in late May last year, which rendered tap water undrinkable for 10 days.
