Chapter 15 Freshwater Resources Flashcards
Used & contaminated water released after use by households, industry, agriculture
Wastewater
Water that has few dissolved ions such as salt
Freshwater
Movement of water from gaseous to liquid thru various water compartments such as surface waters, soil, & living organisms
Water cycle or hydrologic cycle
Body of water found above ground: oceans, lakes, rivers
Surface water
Loss of water vapor from plants
Transpiration
Conversion of water from liquid to gaseous state
Evaporation
Physical water scarcity
Use of water is approaching or exceeding sustainable limits
Conversion of water from gaseous state (water vapor) to liquid state
Condensation
Rain, snow, sleet or any form of water falling from atmosphere
Precipitation
water found underground in aquifer
groundwater
underground, permeable region of soil or rock saturated with water
aquifer
process of water soaking into ground
infiltration
uppermost water level of saturated zone of an aquifer
water table
removal of salt and minerals from seawater to make it suitable for consumption
desalination
inflow of salt (ocean) water into aquifer. Happens when aquifer has lost some of freshwater stores
saltwater intrusion
water discharged into environment
effluent
bacteria found in intestinal tract of animals. monitored for fecal contamination
coliform bacteria
drinkable water. clean enough for consumption
potable
ecosystem that is permanently or seasonally flooded
wetland
structure the blocks flow of water
dam
artificial lake formed when river is impounded by dam
reservoir
