    Good day! Tell me please, is there any information on the distribution of the depression cone in the confined aquifer? For some reason, they always depict a funnel passing through a waterproof layer. How can it spread evenly through the clay layer? It seems to me that the depression funnel in the confined horizon should be enclosed between the impermeable layers, or am I wrong? Thanks!

      Hi, great question! We actually made a video on this. Here is the link: ua-cam.com/video/QjnUO0qqIu8/v-deo.html
      In an unconfined aquifer the draw down will look like a funnel but when we are pumping too much from a confined aquifer that has high water pressure we'll just see the water level in our well lower.
      If there is a large amount of pumping over a long period of time and the water pressure has been lowered we'd still get that same funnel shape of the water and also run the risk of running that well dry. This is why it's really important to know how much you're going to be pumping and if other household/municipalities are pumping from the same aquifer.

    Is there any way to find a confined aquifers? This will helps to find the points to dig the well. Can you explain the tools which helps to find confined aquifers?

      Hi Vineesh, first we have to drill a well and see where we find water and when we start drilling through another layer of sediment or rock this area will produce no water. Sometimes when we are drilling we will get a big gush of water when we hit a confined aquifer because that water is under pressure. At this point we have to record how many feet we have drilled. Once we drill multiple wells we can compare where we found water and at what depth. After that we use modeling to give us an estimate or where confined aquifers are and how deep they are.
      As far as tools most drillers use a large drill tip that also shoots out water (or air) which breaks apart the bedrock and pushes any fragments to the surface. This is called a mud or air rotary drill. Hope this helps!
