Depth of GW in oxidized zone


-I have two borelogs. Please take a look at them. I can't make out the depth of groundwater from them. My professor told me something about its being oxidized. He said it means that the first 3m have been dried out so the borehole does not give us the usual depth of GWL. But I didn't understand exactly what he meant. So I wonder how I should find the depth. Please help me. -Also as you see, in these borelogs there is some numbers about sensitivity which is the strength/residual strength of vane test. I don't know I should use this data in which part of my report and to calculate what! -Beside with what you see, I have also some dynamic cone penetrometer logs that my professor told me it's good for finding about variations of layers in underground. So I wonder if it's of anyother use in geotech investigation report. I really appreciate if you can give me some guides. Thank you so much¤t=16.jpg¤t=20.jpg

The groundwater levels normally will vary through the year. It should be monitored to determine the highest and lowest levels within the borehole depths. A good geotechnical investigation should be project specific. Information needed depends solely on a project. It is very difficult to tell how to use data to calculate and so on.
