  • Description:

DSM was appointed to conduct the necessary ground remediation at this former cleaning facility. During the life of the plant, unacceptable levels of both soil and ground water contamination had materialised as a result of the presence and leaching of oils and cleaning fluid.

The decommissioning of the site was the first step in the construction of a mixed used development including a number of residential properties.

The DSM remediation proposal included site wide excavation to a depth of 2m to remove groundwater for treatment prior to discharging to the foul sewer, and the excavation of contaminated soils for treatment prior to reintroducing them to the permanent works.
The bulk excavation operation ensured that any potential sources of contamination and pathways were removed as a watercourse was introduced through the middle of the development.

The specific soil treatment method was considered the most suitable option given the wet cohesive nature of the soil together with the time of year when the contract was carried out.
