The situation is quite serious - groundwater is important source for water use, including drinking water, and if it gets contaminated, it's very costly and difficult to clean.
Pollution is a serious one. Water pollution, air pollution, and then solid hazardous waste pollution. And then beyond that, we also have the resources issue. Not just water resources but other natural resources, the mining resources being consumed, and the destruction of our ecosystem.
While cheap products are exported to western countries, the waste is dumped mostly in China's back yard, contaminating its air, water, soil and seas.
We copied laws and regulations from western countries, but enforcement remains weak, and environmental litigation is still quite near impossible.
The motivation should come from regulatory enforcement, but enforcement is weak, and environmental litigation is near to impossible. So there's an urgent need for extensive public participation to generate another kind of motivation.
One thing most people would agree is that climate change would add further uncertainties to our already quite tight water supply situation in China.
