Consider the borehole record below (in particular the Water Depth column).

There is a blackwhite inverted triangle at a depth of 23.5020 m. What is the meaning of this symbol?

The white inverted triangle indicates the depth at which water was struck.

There is a whiteblack inverted triangle at a depth of 32.2050 m. What is the meaning of this symbol?

Why has a range been given toThe black inverted triangle indicates the depth to which the water rose after 20 minutes.

My new question is why does the depthwater rise above where it was originally struck? What is this implication of this? Is the location of the black inverted triangle the true location of the water table within the soil? Why was water struck lower than this?
