Pore spaces are the voids in a soil media, in other words, it is the space between the soil particles of sand silt or clay. The space has either air or water in it. An aquifer has millions of pore spaces that are filled with water and acts as a reservoir that we get our water if pumped out or comes to the surface if it is a spring. I hope that helps.
It is one in the same you can use the terms interchangeably. The definition that UC Davis uses is defined as an undesirable change in groundwa- ter quality resulting from human activities
Jerry Delsol Thanks for replying. I have another question. Does the capillary fringe do?? Does it draws water from the saturated zone, and the plants receives waters from the soil??? I'm kinda confused.
Mr. Calculus..Groundwater or water underground can be divided into two zones; unsaturated zone and the saturated zone. The former is water that is directly under the soil surface and is organized into 3 levels or zones, the soil zone, intermediate zone and the capillary fringe which is a transition section between the unsaturated and saturated zone or aquifer. The soil zone extends down about 6-8 feet where most of the plants' roots reside and ultimately where they get their water. As for the Capillary fringe it is found near the bottom of the intermediate zone and and draws water from the top of the aquifer which is the start of the Saturated zone. The Capillary fringe is under negative pressure so water will be drawn up the very small soil pores. In other words. plants receive water from the soil zone that is located in the unsaturated zone and will not draw water from the saturated zone (aquifer). I hope that answered your question.
Jerry Delsol Yeah, I understand now. Thanks for the help! This will be my final question. Difference between unconfined aquifers and confined aquifer? Is it that unconfined aquifer is between the surface water?? Saying that could get contaminated because it doesn't have a layer of impermeable stuff to shield it?? And the confined aquifer is between aquitard and aquiclude so it won't get contaminated by something from the surface? I hope I'm on the right track here.
Mr. Calculus...you are definitely on the right track the confining layer does indeed help protect the confined aquifer. And the unconfined aquifer does have a higher rate of pollution than the confined aquifer. But if the confining layer is comprised or is not continuous it too can be polluted.
Thank you! You made easier to visualize the dynamics in both aquifers.
Thank you Neal I appreciate your comment.
This is a great video, very clear description
Thank you so much for the encouragement I appreciate it.

Ursula Thanks for viewing!
Kyle thanking for watching.
Many thanks for very helpful guidance..
Great description
Best explanation.
This helped so much! Thank you!
This was amazing. Thank you for the help. However, can you explain confined-artesian vs. confined-sub artesian aquifers?
thanks!! this is very helpful.
Thank you. Big help.
thank you it helped me a lot!
Thnx :) Helped a lot!
nice lecture.
thank you so much
Helped me a lot thanks
+jasvinder singh Thanks for watching I am glad I could help!
Thank YOU!!!
very helpful! thanks
tell me more about pore spaces!!!!!
very good! :)
thank you very much
Bay you are welcome and thank you for viewing my video on aquifers!
what are difference between definition of groundwater pollution and groundwater ccontamination
It is one in the same you can use the terms interchangeably. The definition that UC Davis uses is defined as an undesirable change in groundwa- ter quality resulting from human activities

Is aquifer groundwater?
Yes an aquifer is another name for groundwater. Thanks for watching.
