Geology: Water Flavored

Define the following terms:
1. Aquifer
2. Aquifuge
3. Aquiclude
4. Aquitard

This is quite an exciting thread...

1. An underground layer of permeable rock that has groundwater in it
2. An underground layer of rock that is completely impermeable and doesn't allow water to flow through
3. same as aquifuge
4. a layer of low permeability

Aquiclude vs aquifuge (Click to Show Hidden Text)

Both are relatively impermeable, but an aquiclude is saturated with water but an aquifuge is not.

That's correct.

Yay! I had to look that one up, lol.

Okay, what is the difference between hydraulic conductivity, porosity and permeability?

[appleshake123]

I believe this is the answer :
[hide]Porosity is the open space in a rock. Permeability- transitivity of water through the rock. Hydraulic Conductivity is permeability except with the hydraulic gradient involved[/hide]

[aherthabey]

That's correct!
Also, you should put a | between what you want to display and what you want to hide, like this:
[hide ]blah|blah [ /hide]

Your turn! (Or Magikarpmaster629 can go again)

What are two ways chemical reduction is applied to clean contaminants and explain both ways.

can either be pumped out of the aquifer, to be treated with chemical reduction ex-situ; or a 'gradient' of the chemical reduction is placed into the aquifer so when the contaminant passes through the gradient it becomes treated.
