**4. Future Prospects**

Medical geology is truly a multidisciplinary research field, and requires collaboration among researchers, policy makers, and the general public, with groundwater quality research being a fundamental field of this discipline. Hence, for its further promotion, we propose some suggestions that may be fundamental and significant to guiding this discipline:


avoid diseases. Maintaining health does not only include avoiding diseases, but also keeping healthy via an appropriate intake of necessary essential elements through water, food, and other media. Therefore, the geology of health could be a possible replacement for medical geology in the future.
