A thorough review of existing ground-water information may, in some cases, be adequate to estimate rates of migration of pollutants. Analysis of data from well-performance tests and from hydrologic-data stations near a landfill in Anchorage, Alaska, indicates that pollutants migrating downward toward a confined aquifer that supplies water to three municipal wells near the landfill do not pose an imminent threat to the water supply. The analysis helps alleviate some concerns that pollution of municipal wells is imminent. However, because the errors in estimating hydraulic conductivities may be as great as a factor of three, the analysis should not be used as justification to discontinue monitoring migration of the leachate.
