Domestic Heating Oil Spill, Norfolk
During construction of these residential flats poor workmanship on the fuel lines resulted in heating oil leaks on the pipe work. The problem went unnoticed for a considerable period of time until the residents started to complain of odours.
A significant quantity of heating oil had been lost to ground resulting in contamination of both the soil and groundwater. An in-situ dual phase extraction system was utilised to remove vapours and the contaminated liquids.
The pump system and pipe work was placed below ground. The use of planters removed any visual impact of the system which was operated for a 12 month period and achieved significant improvements in the soil and groundwater quality.
