Flow to wells in water‐table aquifers is related to anisotropy, vertical components of flow, well storage capacity, degree of well penetration, and changes in aquifer saturated thickness. The manner and extent to which these factors affect water levels may be evaluated with aquifer test data. Families of type curves describe the typical S‐shaped curves of log drawdown versus log time observed around wells in water‐table aquifers. Comprehensive analysis of water‐table aquifer test data is possible with the array of equations derived largely in the late 195O's to 1970's. Erroneous data analysis will result unless complicating factors are fully recognized and taken into account. This paper reviews existing methods which the author accepts and recommends for ground‐water investigator use.
