Groundwater

Explore the crucial topic of groundwater in this 52-minute lecture. Delve into the geological importance, distribution, and movement of groundwater beneath Earth's surface. Learn about aquifers, wells, and springs, as well as monitoring techniques for water tables. Examine factors influencing groundwater storage and movement through porosity demonstrations and hypothetical flow systems. Investigate environmental challenges such as saltwater contamination and sinkholes. Discover the geologic work of groundwater, including the formation of caves and karst topography. Gain insights into city water systems, artesian wells, and the High Plains Aquifer. Access additional resources from Maryland Geological Survey, USGS, and EPA to enhance your understanding of this vital component of Earth's freshwater system.
