Summary appraisals of the Nation's ground-water resources; Alaska
Chester Zenone, Gary S. Anderson
1978, Professional Paper 813-P
Alaska has enormous surface-water resources, but many of the streams are frozen for most of the year and most contain glacial silt that makes them unacceptable for human use. These factors lend special significance to ground water as a water-supply source, even though perennially frozen ground (permafrost) profoundly modifies ground-water...
