Critical Aquifer Recharge Areas means those land areas that contain hydrogeologic conditions that facilitate
aquifer recharge and/or transmit contaminants to an underlying aquifer. Critical aquifer recharge areas under this title may be established based on general criteria, specifically designated
due to special circumstances, or based on scientific studies and mapping efforts. Factors considered in the identification of critical aquifer recharge areas include depth to water table,
presence of highly permeable soils (specifically Group A Hydrologic Soils), presence of flat terrain, and the presence of more permeable surficial geology. Category I critical aquifer recharge areas
are those areas where the potential for certain land use activities to adversely affect groundwater is high. Category I critical aquifer recharge areas include:
1. Areas inside the five-year time of travel zone for Group A water system wells, calculated in accordance with the Washington State Well Head Protection Program.
2. Areas inside the ten-year time of travel zones in wellhead protection areas when the well draws its water from an aquifer that is at or above sea level and is overlain by permeable soils without an underlying protective impermeable layer.
3. Areas identified as Significant Recharge Areas due to special circumstances or identified in accordance with WAC 365-190-080 (2) (c) as aquifer areas of significant potable water supply with susceptibility to groundwater contamination,
including but not limited to the following:
a. Hansville Significant Recharge Area. The Hansville aquifer is a significant potable water supply that is highly susceptible to the introduction of pollutants. Additional information regarding this aquifer is available from the Kitsap Public Utility District.
b. Seabeck Significant Recharge Area. The Seabeck aquifer is a significant potable water supply that is being developed for use in central and north Kitsap County. Additional information regarding this aquifer is available from the Kitsap Public Utility District.
c. Island Lake Significant Recharge Area. The Island Lake aquifer is a significant potable water supply for the Silverdale area. Additional information regarding this aquifer is available from the Silverdale Water District.
d. Gorst Significant Recharge Area. Aquifers in the Gorst basin are highly susceptible to the introduction of pollutants and provide significant potable water supplies for the City of Bremerton.
e. Poulsbo Significant Recharge Area. The Poulsbo aquifer is highly susceptible to the introduction of pollutants and provides a significant potable water supply for the Kitsap Public Utility District and City of Poulsbo.
4. The department may add, reclassify or remove critical aquifer recharge areas based on additional information about areas of significant potable water supply with susceptibility to groundwater
contamination or based on changes to sole source aquifers or wellhead protection areas as identified in wellhead protection programs
None
