Abstract
This research studies the problem of monitoring the deterioration of small-diameter observation wells. It considers three methods for achieving this task: visual inspection of hydrographs, on-going recording of borehole depth, and analysis of slug tests. The relative merits of these methods are judged in view of the results of a large-scale field survey. The field results indicate that while the first two methods suffer certain disadvantages, the slug test method is a rather reliable tool.
