This is a picture of the white chalky stuff that many people are familiar with on their basement walls. It is often times confused for mold growth. Actually it is just mineral deposits that come through with the water vapor. The biggest thing it tells the inspector is that water vapor is absolutely coming through the wall. So even if his equipment says the humidity is low, (maybe because the weather is nice that time of year), he will know that the humidity has been elevated at some point.
