Video transcript

Hello everyone and welcome to today's video. So the Nubian sandstone aquifer system is considered the world's largest known fossil water aquifer system. The following can threaten the quantity of water in the aquifer system except remember that we're looking for an answer choice that is going to affect something other than the quantity of the water present in this aquifer system. Let's begin by answer choice. A overharvesting and overharvesting in terms of an aquifer is going to refer to over collecting the water that is present in this aquifer. This is going to greatly reduce the quantity of water present there. So we're going to cancel this out because it is going to affect the quantity of water and we're looking for something that won't then we have been in previous paved surfaces. This in previous paid services are going to result in water being collected under them, which is going to prevent this water from going into the aquifer is also going to reduce the quantity of water available there. We're going to cancel this out as well. Let me have changes in precipitation. Well, if it rains more, the quantity of water available in the aquifer is going to increase. But if it rains less the quantity of water available there is going to decrease. This really depends, but this is also going to affect the quantity of water so we're going to cancel it out and soil contamination is the answer that we are looking for. This is actually not going to affect the quantity of the water, but the quality. If we have a contaminated soil, the quality of this aquifer is going to be greatly reduced. Because of this answer choice D is going to be the correct answer choice to this question. I really hope this video helped you, and I hope to see you on the next one.
