Efforts to relate shallow ground‐water quality to the land use near a well lead to several statistical difficulties. These include potential uncertainty in land‐use categorical data due to misclassification, data closure, distributional skewing, and spatial autocorrelation. Methods of addressing these problems are, respectively, the establishment of limits on minimum buffer radius, the estimation of contrasts, rank‐based tests of association, and sub‐sampling to prevent buffer overlap. Relations between the presence of purgeable organic compounds in ground water and land use are used to illustrate these problems and methods.
