Hi collective, 

Does anyone have any experience of this?  I have a situation where a caterer
at a festival had chucked a lot of waste oil - 10's of litres of used chip
fat - out of the back of their concession into the ground, where as well as
making a horrific mess for all the ops contractors - contaminating tentage,
power cabling, signals wires, plumbing etc etc. It had soaked into the
ground at the base of a moderate sized Lawson cypress.  Discovered during
the breakdown period, so it had soaked well in to the ground.  I had  the
affected surface soil scraped off where possible, disposed of, and replaced,
but could not go down far (~100mm ave), because of roots.

 

                I have only found scattered bits on the web - it appears
that there is a considerable BOD (sorry - biological oxygen demand) from the
organisms that metabolise the oil; plus  - probably - direct clogging of
pore spaces and reduction in gaseous exchange.

Has anyone come upon this as an issue, or have any links to info/research
about it.  The oil is likely to have been a mix of Palm and Rape.
