Basic Concepts of Groundwater Hydrology

most California regions, the water table is between 10 and 100 feet below the land surface (in some Southern California desert basins it is as deep as 300 feet). It is in California’s numerous valleys and intermontane basins that ground water exists in the greatest quantity (California and Nevada groundwater basins are shown in Figure 1).

Water Well Design and Construction

The oldest known wells,Qanats, are hand-dug hori-zontal shafts extending into the mountains of the old Persian empire in present-day Iran. Some wells are used for purposes other than obtaining ground water. Oil and gas wells are examples of this. …

Groundwater Sampling and Monitoring

water quality for such a well will be gradual. Shallower wells, particularly domestic wells with smaller pumping rates, should be sampled once or twice a year because they are more prone to short-term variations in groundwater quality and contamina-tion. If problems with well bacteria, well degradation, or iron (from a rusting well cas-
