This is the fundamental source for the supports crushing during coal mining under the unconsolidated confined aquifer in East China.

In a US-backed project, it will store 100, 000 tonnes of carbon dioxide annually in a nearby saline aquifer.

What they have, however, found is that the carbon dioxide has increased the acidity of the water in the aquifer.

Re-injection to the aquifer is less common.

The concentration of petroleum pollutants in the lower aquifer is considerably higher than that in the upper aquifer.
