Summary
Groundwater monitoring involves the measurement and assessment of groundwater levels and quality over time. It is essential for managing environmental risk, supporting compliance, and informing geotechnical and remediation decisions across Australian projects.
Definition
Groundwater monitoring is the process of measuring groundwater levels, flow, and quality over time to assess environmental conditions, contamination, and subsurface behaviour.
Why It Matters
Groundwater monitoring is critical for ensuring environmental protection, regulatory compliance, and informed decision-making.
Managing Contamination Risks
Groundwater can act as a pathway for contaminant migration. Monitoring helps:
- Identify the presence and extent of contamination
- Track movement of contaminants such as hydrocarbons, heavy metals, and PFAS
- Assess risks to human health and the environment
This is a key component of a contaminated land investigation.
Supporting Environmental Compliance
Monitoring programs are often required under:
- National Environment Protection (Assessment of Site Contamination) Measure (NEPM)
- State EPA guidelines and regulations
- Development consent conditions
They provide evidence that environmental risks are being managed effectively.
Informing Remediation and Site Management
Groundwater monitoring supports:
- Design and implementation of a Remediation Action Plan (RAP)
- Evaluation of remediation effectiveness
- Ongoing site management and validation
It ensures remediation strategies are targeted and effective.
Understanding Groundwater Behaviour
Monitoring also informs geotechnical and engineering considerations such as:
- Groundwater levels affecting excavation and stability
- Dewatering requirements
- Long-term ground behaviour
When It's Required
Groundwater monitoring is required where groundwater conditions may impact environmental, regulatory, or engineering outcomes.
Contaminated Land Investigations
Monitoring is essential during:
- Preliminary and detailed site investigations
- Ongoing contamination assessment
- Validation and long-term monitoring programs
Often undertaken alongside groundwater sampling and installation of groundwater monitoring wells.
Development and Approval Processes
Monitoring may be required as part of:
Construction and Dewatering Activities
Monitoring is critical where construction may:
- Intersect with groundwater
- Require dewatering
- Influence groundwater flow or quality
Often integrated with Geotechnical Investigation, Geotechnical Monitoring, and Environmental Monitoring.
Long-Term Environmental Management
Monitoring programs may continue post-construction to:
- Track long-term groundwater quality
- Ensure compliance with regulatory requirements
- Support site closure and validation
