In addition to groundwater maps, these lists also contain technical reports.
Groundwater recharge- and discharge-area maps
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.
Groundwater sensitivity and vulnerability to pesticides maps
Sensitivity is determined by assessing natural factors favorable or unfavorable to the degradation of groundwater when pesticides are applied or spilled on the suface. Vulnerability is determined by assessing how groundwater sensitivity is modified by the activities of humans.
Groundwater-quality classification maps
Groundwater quality is classified by the Utah Water Quality Board based primarily on the total amount of dissolved solids in the water. The lower the total-dissolved-solids concentration, the higher the water quality. Groundwater-quality classification maps show different classes of water in an underlying aquifer (source of undergroundwater). This information can be used to protect higher quality water through more stringent land-use planning.
