Data on physical and chemical parameters related to surface water quality and groundwater quality are presented. The data are based on extensive year-round field sampling. Temporal and spatial trends are described, and data are compared to Alaska Department of Environmental Conservation water quality standards to provide a comparative context.


  • More than 443,000 water quality analyses were completed on samples for the Pebble water quality study.
