| Wetlands may overlie important groundwater aquifers, especially on moraines, eskers, and fluvioglacial deposits. |
| These saline waters get pulled into local aquifers as wells and groundwater supplies are overdrawn. |
| Deep down within fluids or aquifers volatilization is not an important transport process. |
| Shortages have become endemic to many regions, as record drought and population sprawl sap rivers and aquifers. |
| Water can be obtained from streams, rivers, lakes, or underground aquifers, which are used to supply private wells and public drinking water. |
| Irrigation is overwhelmingly the largest use of the water from each of these aquifers. |
