Groundwater is the water occurring beneath the earth’s surface that completely fills (saturates) the void space of rocks or sediment.
The above graphics show how groundwater pumping for agriculture use has lead to decreased river flow in several areas in California. It demonstrates the connection between the groundwater and the surface water. It also shows how severe the consequences (environmental … Continue reading “Areal Problems” →
A groundwater basin is defined as an alluvial aquifer or a stacked series of alluvial aquifers with reasonably well-defined boundaries in a lateral direction and a definable bottom. A groundwater basin is three-dimensional and includes both the surface extent and … Continue reading “Groundwater Basin” →
Most of California’s groundwater occurs in material deposited by streams, called alluvium. Alluvium consists of coarse deposits, such as sand and gravel, and finer-grained deposits such as clay and silt. The coarse and fine materials are usually coalesced in thin … Continue reading “Groundwater in CA” →
Groundwater quality varies from region to region. Surface water quality varies because of erosion, runoff, pollution, plant matter, animal waste, and other possible contaminants. Pore spaces in aquifer naturally purify the groundwater, work like a coffee filter which traps sediments … Continue reading “Quality of Groundwater” →
