You never quite know what is lurking beneath the surface. We recently removed this underground fuel storage tank from a disused filling station site. When we inspected the tank we found this large corrosion hole which could have been a major source of contamination. A persuasive argument for replacing legacy single skin tanks with modern double skin tanks!
We were asked to carry out an environmental ground investigation at a disused transport depot. Not surprisingly this identified diesel contamination at ~2m below ground level.
There was no sign of any obvious contamination source and given the site’s previuous use as a transport depot, we thought it likely that an abandoned below ground fuel tank might be present.
We therefore went back to the site and carried out a shallow trial pitting exercise which revealed……well, you can see for yourself.
