Drinking Water

CRC Planning

Surface water supplies approximately 50% of the State’s water needs for various uses including public water supply. Surface water comes from rivers and streams. Subsurface water, also known as groundwater or wells, supplies 50% of Alaska’s population with wells supplying 90% of the rural Alaska population. Well drillers must keep track of the wells that are drilled and submit this information to the State of Alaska.

Water use data is compiled annually by the Alaska Department of Natural Resources Division of Land, Mining and Water. This data consists of communities and other significant users of water in the state. The Alaska Hydrologic Survey provides technical information that ensures proper and accurate management of the Alaska’s water resources for the benefit of state residents.

Annual water quality reports are required to be distributed to water utility customers. These reports include the contaminants tested for and if any water quality violations occurred. If you haven’t received a report on the quality of your water source, please contact your water utility company. If you have a well, it should be tested annually for possible contaminants. The Alaska Department of Natural Resources oversees water resources and the Alaska Department of Environmental Conservation oversees the water quality of drinking water supplies. The Alaska Hydrologic Survey maintains a database of water quality data reports from a variety of both surface water and groundwater sources throughout the state.

The Upper Copper River Basin, which consists of the Upper Gulkana, Mentasta Chistochina, Mt.Sanford, Tazlina Nelchina, Klutina, Wrangell and Tonsina, has private wells and two coin operated wells as well as water hauling services to meet its drinking water needs. Villages in the Upper Copper Basin have separate water supplies. These types of drinking water sources in the Upper Copper River Basin serve approximately 3,500 people.

The Middle Copper River Basin, which includes the Central Copper and Chitina, has 33 ground water sources, two surface water sources and one ground water (under influence of surface water) source that serves approximately 1,723 people. There are a total of 34 public water systems coming from 36 separate sources.

The Lower Copper River Basin, which includes the Copper River Delta and Bering Glacier, has four surface water sources and serves approximately 2,000 people.
