Sensitive Sites

Overview

what_we_do_pic.jpgLEAP has significant experience in dealing with complex contamination issues on sensitive sites such as those commonly investigated under Part 2A of the Environmental Protection Act 1990. By developing in-house a series of tools and techniques, LEAP is able to assist with planning and costing investigations and assisting with capital grant or internal funding bids. Communication with all stakeholders is a key strength of the LEAP team, and the full range of intrusive investigation techniques are supervised by LEAP’s highly experienced professional staff.

Description and Investigation Design

The site was a former gas works and bulk oil storage depot that was subsequently redeveloped with sheltered accommodation for the elderly, and commercial and residential properties. The Local Authority had prioritised the site for inspection under Part 2A due to its potential to present a significant risk of significant harm to current occupiers, as well as groundwater and surface water. LEAP was employed to undertake Preliminary Risk Assessments on a number of the high priority sites in the district using the unique Phase 1+ report which includes a costed site investigation design and an outline specification document.

The site investigation design included targeting of known former gas works and bulk oil storage structures as well as unbiased investigations of the wider site. The investigation design and outline specification documents were used as the basis for internal and central government funding applications.

Site Investigations

LEAP won the contract for the detailed intrusive investigations at the site, which was occupied throughout the investigations requiring close liaison with residents, property owners, managers, and the Local Authority client. Two phases of soil and groundwater investigation were carried out, with the emphasis on providing the optimum information with the minimum disruption. The investigations included shallow soil sampling inside and outside the former gas works structures; free phase product sampling and testing; deep aquifer drilling and sampling; soil vapour sampling and assessment; and soil asbestos surveys and analysis.

Upon completion of the investigations, the monitoring wells were decommissioned to the satisfaction of regulators and landowners.

Added Value

LEAP was required to undertake a preliminary risk assessment of the site to assess the potential for significant harm, and to design and cost an initial investigation for funding. LEAP worked alongside the contaminated land officer and environmental health department to deliver a scheme that was sensitive to the current land use, scalable in design and costing, yet comprehensive in addressing the various potential risks posed from the past use of the site.

Testimonials

"The principal attraction of working with LEAP was their innovative approach to the organisation and execution of site investigations.

The site was a sensitive residential development and LEAP proved adept at designing and managing the investigation to minimise the impact on the residents.
