The Incident
A leak from the gearbox of a wind turbine caused a large area of synthetic gearbox oil contamination close to a spring well feeding a domestic property. Due to the source of the leak and the turbine spreading the oil across a large area, a significant surface contamination plume impacted and area of approx 1800m2. Concerns raised due to a nearby drinking water supply.
The Solution
The Seed Environmental team were called in to carry out a site investigation to assess the extent and severity of the contamination plume. Seed developed a drinking water monitoring programme to assess if any impact to the nearby drinking water supply followed by a surfactant treatment of all hardstanding areas visibly impacted by the gear box leak.
The Outcome
Following oil degrading surfactant treatment of all visible hardstanding areas and drinking water monitoring over several months, Seed were able to confirm that there was no on-going risk to drinking water supply and that the contamination had been successfully remediated.
