Groundwater |
|
With this kind of aquifer, nothing is impeding the progress of water as it infiltrates down? |
Unconfined aquifer |
|
With this kind of aquifer, there's an impeding later that seperates water from the surface above? |
Confined aquifer |
|
Where's Edinboro's source of water? |
In ground water near Cooper Hall |
|

25%; 10%; 65% |
|
What watersheds are in Edinboro? |
Allegheny Edinboro Lake Ohio River |
|
What is happening when more water is pumped out of an aquifer than is allowed to recharge? |
Ground Water Depletion |
|
What can ground water depletion do to the water table? |
It can cause a cone of depression in the water table |
|
What's the largest aquifer? |
Ogallala aquifer |
|
This is when ground water is pumped out of the aquifer and the ground sinks because of no recharge |
Subsidence |
|
This is any physical or biological, or chemical change in water quality that adversely affects living organisms, or makes the water unsuitable for desired uses. |
Water pollution |
|
What are the 2 types of concerns caused by water pollution? |
Health problems Ecosystem disruption |
|
With this kind of water pollution, it can be pinpointed exactly where the pollution is coming from? |
Point Source |
|
With this kind of water pollution, it's hard to trace to trace pollution source? |
Non-point source |
|
This type of water pollution causes diseases and the major source is human and animal wastes |
Infectious Agents (pathogens) |
|
This type of water pollution has large populations of bacteria decomposing these wastes can degrade water quality by depleting dissolved oxygen needed by aquatic species fish and other forms of oxygen-consuming aquatic species may die |
Oxygen-demanding waste |
|
This type of water pollution adds toxins to aquatic systems and can make freshwater unusable for drinking or irrigation and can affect human health and harm fish and other aquatic life. |
Inorganic chemicals |
|
This water pollutant adds toxins to aquatic systems, can threaten human health: nervous system damage; reproductive disorders; some cancers; can harm fish and aquatic life |
Organic chemicals |
|
This type of water pollutant can cause excessive growth of algae and other aquatic plants, which die, decay, and deplete water of dissolved oxygen, and kill fish. |
Plant nutrients |
|
This type of water pollution can cloud water and reduce photosynthesis, disrupt aquatic food webs, carry pesticides and other harmful substances, clog and fill lakes, settle out and destroy feeding and spawning grounds of fish. |
Sediment |
|
This type of pollution can cause cancer; disrupt immune, nervous, and endocrine systems |
Heavy metals |
|
This type of pollution can lower dissolved oxygen levels and makes aquatic organisms more vulnerable to disease, parasites, and toxic chemicals. When a power plant first opens or shuts down for repair, fish and other organisms adapted to a particular temperature range can be killed by the abrupt change in water temperature. |
Thermal (heat) |
|

|
What year was the safe drinking water act created? |
1974 |
|
This Act set standards for drinking water |
Safe Drinking Water Act |
|
What are the 3 levels of wastewater treatment? |
Primary Secondary Tertiary |
|
This level of wastewater treatment is physical/mechanical, where larger particles are filtered out and smaller particles are allowed tos ettle |
Primary |
|
This level of wastewater treatment is mostly biological, with dissolved organic wastes are biologically degraded by bacteria |
Secondary |
|
This level of wastewater treatment is physical, chemical, and biological and has various techniques to remove phosphates, nitrates, and other pollutants |
Tertiary |
|
What are the main stages of human use of water? |
Water source: environment Pre-use treatment Home/business Wastewater Wastewater treatment Discharge into the environment |
