In June 2017, the Chinese government made a second amendment to the Water Pollution Prevention Act. Based on the first regulation of Water Pollution Prevention Act in 1996, the amendment will increase the punishment for water pollution and the penalty ceiling may be raised to 1 million yuan. According to the statement of the Minister of Environmental Protection, the second revised version further strengthened the responsibilities of local governments, and refined and improved the drinking water safety protection system. Since the legislation in 1984, this law has made a significant and positive contribution to improving the water environment in China. However, the quality of water environment in China is still not promising.
