that has been thought to develop randomly following
contamination and then remediation of a site with petroleum.
The emergence of the phenomenon can occur within
months or years of original contamination and with seemingly
no warning. Low-field NMR has been used to study
these soils and, specifically, the processes of water uptake
that occur in them. Critical aspects in the development
of this phenomenon have been identified as wellspecifically,
a dependence on climatic events in the area and
contamination levels that contribute are suggested.
