The Incident

A single skinned plastic oil storage tank failure allowed an escape of kerosene to impact soils adjacent to a protected 17th century structure.

The site in Co. Tipperary was located in a karstified area with extremely high groundwater vulnerability. The leak source occurred just 100m from the drinking water abstraction well. These risk factors led to severe impact to the localised groundwater table and to the onsite drinking water abstraction well.

The well served both the dwelling and the stud farm providing drinking water for both human and animal consumption.

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. A temporary mains water connection was arranged to maintain the functionality to the stud farm and allow the client to remain in residence. Seed deployed light non-aqueous phase liquid (LNAPL) skimmer pumps to remove the heavy surface contamination from the abstraction well before commencing a groundwater treatment & monitoring programme. The programme included gathering data on groundwater directional flow over a period of 12 months from 8 monitoring wells installed around the farm and stud along with laboratory analysis of groundwater samples for presence of kerosene contaminants.

The Outcome

Following the successful remediation and groundwater monitoring programme, Seed identified a safe location for a new drinking water abstraction well to be installed within the site boundaries. This new well was monitored over a period of time to ensure continued compliance with generic assessment criteria for drinking water. Seed’s works safely returned the drinking water amenity to the dwelling and stud farm from the new onsite abstraction well, this also significantly reduced the costs to the client of maintaining a permanent mains connection for the dwelling and stud farm.
