One of China's most critical pollution issues, that of water pollution has taken a turn for the worse, at least on the Huangpu River, the main waterway and water supply for Shanghai.

For the last three months, China has had an elevated instance of pigs dying from Porcine Circovirus, a common swine disease that doesn’t affect humans. At least 10,000 pigs in the counties of Jiaxing and Pinghu have died in the last three months.

China has a had a serious problem with agricultural waste, and now, the swine are showing up dead in the Huangpu River, the main water source for Shanghai. By today, at least 2,200 dead pigs have been fished out of the river where farmers a dumping the dead swine. Eartags on the dead animals verify this.

The Chinese government has issued statements saying that dispite the inordinate number of stricken pigs found floating in the water, the water is safe to drink. The water supply bureau says that they are testing the water hourly and it shows no sign of contamination.

Chinese online beg to differ however, and online microblogs are telling people in Shanghai to be careful of the water they are drinking. Many are questioning the government’s assessment that the water is not contaminated and fit to drink.

The government has 12 boats on the river still fishing the dead swine from the river.

The dead pigs have been tracked back to two farms upriver from Shanghai.
