Product Recovery & Spill Response

VertaseFLI was instructed by the client to recover free phase product following a spill from a heating oil tank where product had escaped into the ground and nearby stream. VertaseFLI was asked to provide an initial solution to recover this product and limit further impact to the stream before a remediation strategy could be finalised. The site itself was located in a busy carpark at the rear of an office block in a built up area and any solution provided would have to minimise disruption to the residents.

Further Information

After installing spill response equipment into the stream, VertaseFLI undertook site investigation works to establish the mobility of the product and its distribution. Due to the busy nature of the office car park and to minimise disruption, this work took place over a weekend.
Once the location and the likely flow path of the product had been determined, VertaseFLI mobilised several discrete, low impact skimmer systems to site to recover the free phase product. The systems consisted of automated self-contained down-borehole band skimmers, selected to reduce the disturbance of the product-groundwater interface, therefore reducing potential mixing and emulsification in the well and providing an efficient method of product separation and recovery in a compact space.
The skimmers utilised a self-contained low power solution running off a solar panel so no external power supply or generator was required. The systems were designed to be extremely quiet. This combined with the small foot print (1.5m x 1m) resulted in minimal disturbance to the client’s tenants in the nearby office building.
Product levels were reduced from nearly half a metre in places to millimetres and the site is now in the process of being closed out.
All works were undertaken in consultation with and approved by the Environment Agency.
