Phase 2 contaminated land assessments are undertaken to obtain information on soil and groundwater conditions, usually where a potential issue has been identified during an initial assessment.

This will generally involve intrusive investigation works such as the excavation of trial pits, advancement of boreholes or installation of monitoring wells.

Soil and/or groundwater samples are then sent for chemical laboratory analysis, and the data obtained forms the basis of a quantitative risk assessment.

Adeptus carries out all phase 2 sampling  and investigation works in line with BS 10175 best practice guidance, and risk assessment to the standards required by Environment Agency publication CLR11.

'More' is not always better, and with experience and insight it is possible to optimise an investigation regime, balancing costs constraints against the level of data and surety required.

All of the above should be based on a well defined conceptual site model (CSM) (generally developed at phase 1). Phase 2 assessment should focus on reducing or eliminating uncertainties to refine the CSM.

The methods utilised will be determined by the nature of the site, access, geology, and the contaminant linkages of concern.

Phase 2 Assessment Objectives

A phase 2 assessment may be required to discharge a planning condition, investigate potential environmental liabilities, or to enable the development of a remediation strategy.

The common objective in all of these cases is ultimately to ascertain the presence and extent of ground contamination affecting the site, and whether there is a significant risk to human health or the environment.

Where a regulator, such as the local authority or Environment Agency are involved, the scope of a phase 2 investigation should be agreed with such parties before proceeding on site, in order to ensure the relevant concerns are addressed and subsequent risk assessment will be acceptable.

Many investigations can be conducted efficiently with the use of simple machine-excavated or even hand-dug trial pits, which also allow visual inspection of the soil profile or any made ground. Where sampling at greater depths, or groundwater monitoring is required, a borehole investigation and monitoring well installation may be necessary.

Phase 2 Site Investigation Report

Our phase 2 investigation reports are always prepared by the engineer supervising the works on site and retrieving the samples. Chemical concentrations returned from lab analysis are screened against generic or site specific assessment criteria, with overall assessment findings presented in a concise report and summarised in plain language.

Where necessary, we will also liaise with any third parties such as the local authority before commencement and after the works, to ensure the investigation objectives are properly established and addressed in the report.
