JPG are currently involved in the Geoenvironmental studies of the commercial development of 52 acres of land within the Lancashire Business Park, Leyland.
The wider site area holds a medieval legacy, with the site historically occupied by Lower Farrington Hall (with moat), Farm and Mill between 1848 and 1982. During the 1980’s and early 1990’s, both the northern and central parts of the site were utilised as a refuse tip, predominantly for foundry waste.
A combined phase 1 desk study assessment and following phase 2 site investigation were undertaken. The following potential sources of contamination and geo-environmental constraints encountered are as follows:
- Refuse Tip (Foundry Waste)
- Locally deep made ground
- Heavy metals and total petroleum hydrocarbons within the refuse tip soils
- Potential for hazardous ground-gas
- Potential for obstructions and sub-structures in regards to Farrington Mill (which lies outside of the archaeological point of interest)
Surface water sampling and chemical testing was undertaken within the River Lostock, flowing adjacent to the site. This was to enable a wider environmental impact understanding of the site, to inform the environmental risk assessment
Geotechnical testing of the soils within the former refuse tip is currently being undertaken to establish a suitable solution for re-engineering the site for future commercial development.
This project is currently ongoing with gas and water monitoring being undertaken weekly.
