Abstract
There is an implicit relationship between the frequency of sampling and the value of information obtained. This relationship is briefly explored by a study of nitrates in aquifers of the Quaternary age and fluorides and sulfates in aquifers of the Cambro-Ordovician age in Iowa. The ambient distribution of these chemicals, in general, is positively skewed with a significant number of observations in the lower end of the feasible range. It is shown that a much broader perspective of the distribution of these chemicals in ground water can be obtained by studying a whole spectrum of parameters (quantiles) ranging from the minimum to the maximum, rather than just the mean or the median alone. Simple random samples of varying sizes drawn from the available data base revealed that many parameters of location, such as the quantiles, of nitrates, fluorides, and sulfates in selected aquifers can be estimated closely by samples of sizes 50, 100 and 250. Results based on such hindsight warrant further investigation of the behavior of sampling distributions of a set of high priority chemicals in different hydrogeological environments.
