Groundwater Risk Assessments Services
Where a Controlled Water is deemed to be at potential risk from contamination, be it either a surface water course or groundwater, a Quantitative Groundwater Risk Assessment (QGRA) may be required. Commonly, this is needed to satisfy the requirements of the Environment Agency as a Consultee on a Planning Condition, though assessments may also be undertaken for other regulatory compliance and corporate due diligence purposes.

Groundwater risk assessments can vary from a simple Level 1 Assessment, comparing groundwater concentrations against drinking water or EQS standards, through to more detailed computer based modelling, taking into account fate and transport properties, aquifer properties and contaminant degradation. The purpose of a Groundwater Risk Assessment is essentially to assess what level of contaminant could safely be left in-situ without detriment to a defined receptor and hence is generally used to derive clean up levels during the remediation phase or to demonstrate that a certain level of contaminant is of no cause for concern.
Applied Geology has experience in undertaking groundwater risk assessments in a broad range of situations. This experience has helped many of our clients reduce remedial costs which would have previously been associated with a site by a combination of technical expertise, close regulatory liaison and commercial awareness. Whilst the additional costs associated with a more detailed QGRA may be significant in some cases, these are almost always outweighed by potential financial savings and/or programme improvements.
