DESCRIPTION
A power point of vocabulary relating to water resourcesTRANSCRIPT
Water resources
Aquifer
Chlorinated hydrocarbon
Inorganic Fertilizer
Desalination
Dissolved Oxygen
Euphotic Zone Photosynthesis producing most
oxygen
Eutrophication
Increased Nitrates,
Phosphates (naturally or
culturally) from external sources
Evaporation
Floodplain
Groundwater
Natural Capital
Water, trees, grassland, soil, etc…notice the change in allocated natural capital for wildlife versus humans
Natural Recharge
• If we leave it alone how much will these areas recharge their supply?
Nondegradable pollutant
• Plastics, Lead, Many Inorganic Toxins, Mercury
Slowly Degradable Pollutant
• Material that does biodegrade but occurs slowly over time to acceptable levels
Oxygen Demanding Wastes
• Waste products which require Oxygen in order to break down. They remove lots of DO from water…
Point source
• Single point of pollution source
Primary and Secondary Sewage Treatment
Large solids are
filtered out
Primary
90% of leftover waste is digested
by aerobic bacteria
secondary
Recharge area
• Area where water passes through to an aquifer
Reliable Runoff
• Can be depended on and calculated on a regular basis
Salinity
Saltwater Intrusion
Using freshwater faster than it can be recharged so saltwater intrudes
Sedimentary Rock
Septic TankAerobic bacteria decompose waste and sludge settles. Effluent flows
out into ground
Sludge
Leftover, toxic chemicals, infectious agents, and settled solids removed from waste water
Surface Runoff
Water Pollution
Chemical or physical influences which may be harmful to living organisms
Water Table
Zone of AerationZone of
saturation
Zoning
• Regulation (by law or interpretation of law) how parcels of land and the water present shall be used
