Groundwater Recharge- and Discharge-Area Maps
Map of recharge and discharge areas for the principal valley-fill aquifer, Sanpete Valley, Sanpete County, Utah: Map 174.
These maps show the relative vulnerability of underlying aquifers to surface sources of potential pollution based primarily on the presence or absence of protective fine-grained layers (sediments or rocks) and water levels in wells completed in the aquifer.
Primary recharge areas do not have protective fine-grained layers and vertical groundwater movement is downward; these areas are the most vulnerable to pollution from land-surface activities.
Discharge areas have protective fine-grained layers and vertical groundwater movement is upward; these areas are least vulnerable to pollution. These maps can be used by land-use planners to help properly site facilities to avoid unintentionally polluting groundwater.
