Acid mine drainage

Answer 1

An environmental problem related to the discharge of acidic waters resulting from the weathering of sulfide minerals, such as iron pyrite, associated with coal and sulfide mineralization of important metals, such as copper, silver, and zinc.

Question 2

Biochemical oxygen demand

Answer 2

A measure of the amount of oxygen necessary to decompose organic materials in a unit volume of water. As the amount of organic waste in water increases, more oxygen is used, resulting in a higher BOD.

Question 3

cultural eutrophication

Answer 3

ltural eutrophication
Rapid increase in the abundance of plant life, particularly algae, in freshwater or marine environments resulting from input of nutrients from human sources to the water.

Question 4

Nonpoint sources

Answer 4

Diffused and intermittent sources of air or water pollutants.

Question 5

Question 8

reclaimed water

Answer 8

Water that has been treated by wastewater handling facilities and may be used for other purposes on discharge, such as irrigation of golf courses or croplands.

Question 9

Septic tank

Answer 9

Tank that receives and temporarily holds solid and liquid waste. Anaerobic bacterial activity breaks down the waste, solid wastes are separated out, and liquid waste from the tank overflows into a drainage system.

Question 10

Wastewater renovation and conservation cycle

Answer 10

A process of recycling liquid waste that includes return of treated wastewater to crops or irrigation and continued renovation through recharge of groundwater; the reused part involves pumping out the groundwater for municipal, industrial, or other purposes.

Question 11

water pollution

Answer 11

Degradation of water quality as measured by biological, chemical, or physical criteria.
