Natural Resources Planning Flashcards
Earth Day
The first Earth Day was April 22, 1970.
Metropolitan Water District of Southern California
was established in 1927 to create the Colorado River Aqueduct. The Colorado River Aqueduct, a water pipeline to Los Angeles, was built between 1933 and 1941 and is owned and operated by the Metropolitan Water District of Southern California.
Rachel Carson
Author of Silent Spring, which was published in 1962. In the book, Carson examined the dangers of chemical pesticides, such as DDT, on plants, animals, and humans. The book greatly influenced the way people think about the environment.
Effluent Standards
set restrictions on the discharge of pollutants into the environment. Effluent guidelines reduce the discharge of pollutants that have serious environmental impacts. The EPA has effluent guidelines for more than 50 categories.
Point Source Pollution
is discharged directly from a specific site, such as a sewage treatment plant or an industrial pipe.
Non-Point Source Pollution
contaminated runoff from many sources
Potable water
water that is safe to drink
Aquifer
one or more strata of rock or sediment that is saturated and sufficiently permeable to yield economically significant quantities of water to wells or springs. an aquifer includes any geologic material that is currently used or could be used as a source of water within the target distance limit. Wells can be drilled into aquifers and water can be pumped out. Precipitation eventually adds water (recharge) into the porous rock of the aquifer. The rate of recharge is not the same for all aquifers, through, and that must be considered when pumping water from a well.
Estuary
an area where freshwater meets saltwater
Lagoon
a shallow body of water located alongside a coast
Marsh
a type of freshwater, brackish water or saltwater wetland found along rivers, ponds, lakes, and coasts. It does not accumulate appreciable peat deposits and is dominated by herbaceous vegetation.
Reservoir
a pond, lake, tank, or basin that can be used for the storage and control of water, and can be either natural or man-made
Surface Water
includes rivers, lakes, oceans, ocean-like water bodies, and coastal tidal waters
Swamp
a freshwater wetland that has spongy, muddy land and a lot of water
Watershed
a region drained by, or contributing water to, surface water
