Aquifers – Water in Porous Media Understanding Groundwater (Oregon State University)

Porosity vs Permeability

Sources of Porosity in Media Well-sorted, high porosity Poorly-sorted, poor porosity Sorted porous rock, very high porosity Cemented sorted rock, very low porosity Solution porosity in rock Fracture porosity in rock Freeze and Cherry (1979)

Porosities of Typical Media Freeze and Cherry (1979)

Aquifer Types - Media Understanding Groundwater (Oregon State University)

Aquifer types - Geometry Understanding Groundwater (Oregon State University) Unconfined Confined

Aquifer Types Ward and Trimble Fig after Heath (1983)

Groundwater - Surface Water Interactions Understanding Groundwater (Oregon State University)

Gaining … …and Losing Reaches Understanding Groundwater (Oregon State University)

Groundwater Recharge Where does the groundwater that you drink, come from? Understanding Groundwater (Oregon State University)

Groundwater Concerns Water Quality Septic systems Home, garden, and automotive chemicals Fertilizer Applications Commercial use of pesticides Animal lots Hazardous materials used in business and industry Transportation/handling of bulk fuels & chemicals Storage tanks--underground and aboveground Storage lagoons Landfills and dumps Urban runoff
