Re: Hydrogeology C
Ogallala, Ozark plateau, and the Mississippi river valley aquifer Since the answers to this are rather ambiguous, I'll go ahead and ask a question:tm-scioli wrote:Name 3 major aquifers in the US
Give a basic definition of the term 'aquifer' and explain what properties make it different than something that isn't an aquifer.

Re: Hydrogeology C
An aquifer is one or more geological strata that are water bearing and capable of transmitting water at an appreciable rate. An aquifer refers only to the zone where all pore spaces and interstices are saturated with water.

Re: Hydrogeology C
I'd say that's mostly right. However, aquitards and aquicludes can also have pore spaces filled with water. The difference is, aquifers have high permeability which allows them to transmit water with a reasonable speed, whereas aquitards and aquicludes transfer the water slowly or not at all.tm-scioli wrote:An aquifer is one or more geological strata that are water bearing and capable of transmitting water at an appreciable rate.

Go ahead.

Re: Hydrogeology C
1. Lnapl is light non aqueous phase liquid(Less dense than water I guess) and Dnapls is dense non aqueous phase liquid(denser than water) 2. Do you mean transmitivity- the water flow rate in an aquifer? If not, guess I have to learn more.tm-scioli wrote:1. LNAPl vs. DNAPL
2. what is transitivity?

Re: Hydrogeology C
Yeah, 2 is my bad. The correct spelling is transmissivity, and it's specifically the horizontal flow rate of water of the entire thickness of the aquifer (it's usually measured as hydraulic conductivity times thickness

Re: Hydrogeology C
I ran into a question regarding the time of a contaminant reaching other wells. The question was: Approximately how long will it take for the BTEX to travel from the source (well E) to the nearest well in danger of being contaminated? The answer was: 2-4 years. How am I supposed to solve this? Any expertise would be greatly appreciated!
