Question

1. An incinerator is

a	a waste treatment process that involves the combustion of organic substances contained in waste materials.
b	a landfill designed to contain toxic chemicals.
c	a disposal site for the disposal of waste materials by burial each day.
d	waste disposal approach that involves several material or mechanisms for isolating the waste from the environment.

2. Eutrophication is

a	a positive form of stress having a beneficial effect on health, motivation, performance, and emotional well-being.
b	the development of high nutrient levels in water that often leads to an algal bloom.
c	a tongue of contaminate-rich water extending away from a point source of groundwater pollution in the direction of groundwater flow.
d	a body of water along a coastline that contains a mix of fresh and salt water.

3. A sanitary landfill is

a	a waste treatment process that involves the combustion of organic substances contained in waste materials.
b	a disposal site for the disposal of waste materials by burial each day.
c	a landfill designed to contain toxic chemicals.
d	waste disposal approach that involves several material or mechanisms for isolating the waste from the environment.

4. Anaerobic decomposition is

a	a graph depicting oxygen depletion followed by re-oxygenation in a stream system below a source of organic waste matter; caused by aerobic decay of the organic matter.
b	decomposition using or consuming oxygen.
c	the quantity of oxygen required for aerobic decomposition of organic matter in a system.
d	decomposition that occurs without using, or in the absence of, oxygen.

5. Pump and treat is

a	a tongue of contaminant-rich water extending away from a point source of groundwater pollution in the direction of groundwater flow.
b	a method to remove contamination by exposing the contaminate to the action or effect of air or to cause air to circulate through.
c	the natural processes of dilution, dispersion, precipitation, sorption, biodegradation, bioaccumulation, volatilization, and/or chemical and biochemical stabilization of contaminants (in general), occurring in terrestrial or aquatic environments, which effectively reduce contaminant mobility, bioavailability, toxicity, or concentration to levels that are not overly harmful to human health and ecosystems
d	an approach to groundwater purification whereby the water is extracted prior to treatment.
