Abstract:
Two water wells at the Water Resources Research Center (WRRC), The University of Arizona, were used as a thesis study to examine changes in the wells’ efficiencies. Seismic study, grain-size analysis, constant pump tests, and step-drawdown tests were used to explain the layered conditions and the hydraulic characteristics of the water -bearing media. One of the wells R₁ seems to be affected by the recharge tests that have been conducted over a long period; formation losses increased from 14 sec/ft² in 1967 to 19 sec/ft² in 1970. Both wells, R₁ and R₂, exhibited high well loss values, but well R₂ seems to be more highly affected. Losses in well R₁ are suspected as being caused by plugging of the aquifer by fine suspended particles and entrained air. Well losses in well R₂ are probably caused by inadequate well diameter and casing perforations. Boundary effects might be another cause for the change in discharge rates.
