Paper Summary

Groundwater extraction in Irricana, Alberta, was based on short pumping tests, leading to overestimation of safe yield. A new test revealed aquifer boundaries were not considered, causing excessive drawdown. This study suggests a better method for estimating storage depletion to improve groundwater management.
