Name: Score:77 Multiple choice questions
Term 1 of 77
what is the largest resevoir of freshwater
water is redirected from higher to lower points of the river instead of a dam
a) zone of aeration: above water table where pores in the rock do not contain water
b) zone of saturation: where pores in the rock are completely filled with water
a heat source boils water to create steam and power a turbine connected to a generator
groundwater found in pores of sediment and fractures of bedrock
Term 2 of 77
reactive wall
methane and natural gas trapped in the fractures of shlae
a non conformity that traps materials under the surface
a wall of reactive material neutralizes DNAPL as it passes through
a row of wells or gates release chemicals into a plume to neutralize contaminant
-used for DNAPL
Term 3 of 77
what other factors (2)
groundwater found in pores of sediment and fractures of bedrock
the source of pollutant disperses until concentrations are below regulated limits
a layer in the groundwater where the groundwater pressure is zero
permeability: material property for how easiry water can flow through rock a soil
,Term 4 of 77
chemical flushing
underground geologic structures that tend to trap any oil or natural gas if it is present
methane and natural gas trapped in the fractures of shlae
ice cores: layers in ice record prehistoric carbon dioxide levels
greenhouse effect
chemicals are pumped into the ground upstream to be removed later downstream
-DNAPL

the total head/ distance (slope of water table)
, Term 10 of 77
aquitard
impermeable layer that prevents water movement

-extracted by fracking
a heat source boils water to create steam and power a turbine connected to a generator
water is redirected from higher to lower points of the river instead of a dam
