Term
104. Aquifer Depletion[image]
Definition

Def - Groundwater depletion, a term often defined as long-term water-level declines caused by sustained groundwater pumping, is a key issue associated with groundwater use.

Sen -

105. Salt Water Intrusion

Definition

def- is the movement of saline water into freshwater aquifers, which can lead to contamination of drinking water sources and other consequences.

 

Sen-

Such a saltwater saucer of fresh water is maintained full to overflowing by the rainfall, and owing to the frictional resistance of the sand and to capillary action and the fact that a given column of fresh water is balanced by a shorter column of sea water, the fresh water never sinks to the mean sea-level unless artificially abstracted.

Definition

Def -  is the process of removing out-dated, dangerous, or ecologically damaging dams from river systems. There are thousands of out-dated dams in the United States that were built in the 18th and 19th centuries, as well as many more recent ones that have caused such great ecological damage, that they are proposed for removal.


Sen He received his earlier education in his native city, until the removal of his family in 18c8 to Boston.

Term

108. Agriculture effects on freshwater


[image]

 

Definition

Def - Due to inappropriate water management and irrigation technology, water run-off from fields to adjacent rivers, wetlands and lakes is common. This run-off, however, does not only contain soil sediments but also pesticide residues, salts and fertilisers.

Sen - The region contains most of the country's rain-fed agriculture.

Term

109. Recreational effects on freshwater

Def - are sources ofwater that are useful or potentially useful. Uses of water includeagricultural,industrial,household,recreational andenvironmentalactivities. 

Sen - Several of the marine and many species of freshwater algae are peculiar to the island.

 



Term

110Non-point source pollution

 




[image]

Definition

Def - Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage or hydrologic modification. Nonpoint source (NPS) pollution, unlike pollution from industrial and sewage treatment plants, comes from many diffuse sources.

Sen - 

Term

111.Point source pollution


[image]

Definition

def - is a single identifiable source of airWater pollution,thermalnoise or light pollution.

Sen - Water pollution coming from a single point, such as a sewage-outflow pipe

Term

112.Primary waste water treatment



 [image]

Definition

Def - is the process of removingcontaminantsfrom wastewater, primarily from householdsewage

Sen - The wastewater reclamation pond has a certain odor to it. 

 

Term

113. Secondary waste water treatment

 

[image]

 

Definition

Def - is a treatment process for wastewater (or sewage) to achieve a certain degree of effluent quality by using a sewage treatment plantwith physical phase separation to remove settleable solids and a biological process to remove dissolved and suspended organic compounds

Sen -
