Groundwater Chemistry and Water Quality

  • PDF iconAquifer Sensitivity (Susceptibility) Analysis (pdf): Provides a summary of Oregon's approach to evaluation of the relative potential of an aquifer becoming contaminated from activities at the surface.
  • PDF iconGroundwater Training Manual (pdf): Contains basic information about groundwater hydrogeology (i.e., the origin, occurrence and movement of groundwater). Also discussed are groundwater contamination and protection, well construction, and data that water systems should consider collecting.
  • PDF iconNatural Factors Influencing the Composition of Groundwater (pdf): Describes natural compositional variations (and causes) that might occur in groundwater. Groundwater is not constant in its chemical and physical characteristics. Seasonal changes in taste, odor and appearance are also common.
