Groundwater Risk Assessment
A Groundwater Risk Assessment evaluates whether contamination present on or near a site could adversely affect controlled waters, including groundwater and surface water receptors. Using a staged, risk-based approach, we assess source–pathway–receptor linkages and determine whether unacceptable risks are present.
Our assessments are proportionate to site conditions and development proposals, ensuring that risks are clearly defined and appropriately managed without unnecessary complexity.
What this Service Includes
- Review of site geology, hydrogeology and hydrology
- Refinement of the Conceptual Site Model
- Qualitative groundwater risk assessment
- Quantitative risk assessment using recognised models (where required)
- Source–pathway identification
- Aquifer vulnerability assessment
- Groundwater and surface water risk assessment
- Clear conclusions and recommendations for further investigation or remediation
Our Approach
Our groundwater risk assessments follow a structured, evidence-based methodology aligned with current regulatory guidance and best practice.
Our approach includes:
Proportionate application of qualitative and quantitative assessment methods
Use of recognised models and conservative assumptions where appropriate
Clear justification of risk significance and compliance with standards
Transparent presentation of results and limitations
Practical, regulator-focused recommendations
We focus on providing clarity and confidence for planners, regulators and project teams.
Why a Groundwater Risk Assessment is Essential
A robust groundwater risk assessment is essential where development has the potential to impact controlled waters. It supports planning approval, discharge of environmental conditions and protection of groundwater resources.
By identifying and addressing risks at an early stage, this assessment helps avoid regulatory delays, design changes and unexpected costs later in the project lifecycle.
