46%Groundwater that is actually usable
Groundwater (IPOR)water that INFILTRATES into the ground, PERCOLATES into geologic material, and moves back into the OCEAN
GravityPulls water into the ground
Ogallala Aquifercorn, wheat, alfalfa grow. if irrigation continues, aquifer will be destroyed i n10 yrs.
Caliche(OG Aquifer) Calcium Carbonate = Limestone layer
Phreatic zonegroundwater in Saturated zone
Nado zonegroundwater in Unsaturated zone
PorousUnsaturated
PermeableSaturated
Water Tablesurface water, lakes, streams, etc. Coincides w/ topography of land.
Rechargedetermined by fluctuation of water table due to climate change.
Aquifera geologic unit saturated with water, through which water can readily move.
(Unconfined) Aquiferopen at the top
(Confined) Aquiferenclosed above and below by strata that do not allow water to pass
DARCY's LAW (Q =KIA)Discharge = (conductivity)(Hydraulic gradient)(cross-sectional Area)
V = K ((h1– h2)/ L)Velocity = (conductivity)(
Restrictions of groundwaterfriction, adhesion to mineral surfaces, porosity, permeability
hard waterlots of calcium
soft waterless than 60 mg/1 dissolves salts
Radonradioactive, insoluble gas (found in VA, second leading cause of lung cancer)
Cone of depressionsink a well into the groundwater system, and we remove water at a rate such that the groundwater table in the local region sinks
NITRATEmost common contaminant of GW
SALTsecond most common contaminant
