The geographical location and areal extent of each of the areasmonitored is indicated on Plate 1. The selection of the individual wells sampled is governed, to a large extent, by the availability of well Sufficientlogs. informa- tion such as depth, aquifers encovintered, and depths of perforations is desirable for each sampled well to assure that data obtained are useful. -3- are added or deletedWells to, from, the network according to changing groiind vater conditions in an area. For example, a well showing prominent effects of sea-water intrusion is generally removed from productive use and, in many instances, sampling becomes impracticable. Accordingly, another well is substituted, if available. Tests made of ground water quality include mineral and radio- logical determinations. The frequency of sampling, type of analysis, and density of the sampling network for mineral tests depend largely on the conditions in the area being monitored.
