Well-Withdrawal Footprint Mapping
A simple method for mapping groundwater withdrawals at wells provides an intuitive visualization of the magnitudes by displaying an area, the 'footprint', centered on each well to represent its volumetric rate. Footprints for closely spaced wells are combined to equitably display the area corresponding to the combined withdrawals. The size of the footprints on the map are controlled by a user...
Groundwater Use in the United States
Groundwater is one of our most valuable resource—even though you probably never see it or even realize it is there. Groundwater is essential for irrigation and human use in many parts of the country. The use of groundwater in the United States in 2015 is described below.
Domestic Water Use
Domestic water use is water used for indoor and outdoor household purposes— all the things you do at home: drinking, preparing food, bathing, washing clothes and dishes, brushing your teeth, watering the garden, and even washing the dog. At the U.S. Geological Survey (USGS), domestic water use refers to the amount of water that is "self-supplied", or water withdrawn directly by users, such as from...
Bacteriological quality of groundwater used for household supply
In fractured bedrock aquifers used for domestic supply conditions can exist where contaminants such as bacteria are not filtered out by the soil. Once in the fracture system, little additional filtration takes place. The results of a synotic sampling of domestic wells in the Lower Susquehanna River basin, Pennsylvania and Maryland, showed that bacteria concentrations were higher in areas with high...
