| The Application of Environmental Isotopes to Hydrogeology and Environmental Geology |
| Stable isotopes, as labels of the origin of water, have become important tools in hydrology and environmental geology.Ef-forts have also been made at using stable isotopes to quantify some hydrological processes in nature. The difficulty, however, lies in the determination of the labels. Many environmental radioisotopes, as chronometers, can be used in groudwater dating, but only tri-tium and radiocarbon are suitable for practical purposes. Nevertheless, radiocarbon is not easy to tackle in that it is difficult to deter-mine the initial carbon -14 activities at the time when the water reaches the water table. |
