Abstract:

Three fundamental issues to be considered in the design of ground water monitoring programs are 1) choice of parameters for characterizing contaminant sources, 2) determining the areal and vertical placement of monitoring points, and 3) the use of data collection and analysis procedures to distinguish temporal trends in water quality. Parameters chosen for ground water analysis should be characteristic of the contaminant source, amenable to the selected sampling method, and available as part of common commercial laboratory services. The siting of the borings, and the determination of well screen elevations should be based on a real-time water quality monitoring program operated in conjunction with the drilling. Drilling techniques which allow samples to be collected as drilling progresses should be given preferential consideration. These considerations will allow individual geologic strata to be sampled and thus allow wells to be installed optimally. Monitoring programs should have overall data analysis goals in mind, and the data collected must be adequate to evaluate the goals of the program.
