Environmental Monitoring

Tailored environmental monitoring to manage risk, meet approval conditions, and support defensible, regulator-ready reporting.

Why Environmental Monitoring Matters

Monitoring is required for:

  • Development Approvals (DAs) and construction conditions

  • Environmental Protection Licence (EPL) compliance

  • Contaminated land investigations and remediation

  • Due diligence and planning approvals

  • Long-term operational risk management

We support developers, contractors, operators, and councils in delivering reliable data and insights — aligned with NSW EPA, council, and planning requirements.

  • Compliance with DA conditions and the NSW Noise Policy for Industry

  • Reporting for council, EPA, or community stakeholder requirements

Soil & Sediment Monitoring

  • Soil contamination assessment for NEPM, DA, and remediation

  • Sediment testing for stormwater and construction runoff

  • Acid sulfate soil monitoring and validation

  • Laboratory analysis for heavy metals, pH, TAA, ANC, and more

Soil Vapour & Landfill Gas Monitoring

  • Soil gas sampling for volatile organic compounds (VOCs), SVOCs, methane, and carbon dioxide

  • Vapour risk assessments for redevelopment of former fuel stations, industrial sites, and landfills

  • Soil vapour bores installed to EPA and NEPM (ASC) standards

  • Methane and explosive gas screening for planning and safety compliance

  • Vapour intrusion risk screening to inform DAs, remediation, or site audits

Landfill Environmental Monitoring

  • Groundwater, surface water, and leachate monitoring at active or legacy landfills

  • Landfill gas (methane, CO₂, O₂) monitoring from perimeter bores

  • Boundary monitoring for dust, odour, noise, and vibration

  • Preparation of Annual Environmental Monitoring Reports (AEMRs)

  • Programs tailored for EPA-licensed landfills and nearby developments

Construction & Operational Monitoring Programs

  • Ongoing site monitoring aligned with CEMP, OEMP, or remediation plans

  • Real-time alerts and exceedance notifications

  • Monthly, quarterly, or rainfall-event-based reporting

  • Post-construction and validation monitoring

  • Stakeholder or community-facing environmental performance reporting

Frequently Asked Questions (FAQ) – Environmental Monitoring

Q: What is environmental monitoring and why is it required?

Environmental monitoring involves collecting data on air, water, soil, noise, dust, and vapour to assess environmental conditions and track the impact of construction, remediation, or operational activities. It’s required to:

  • Meet conditions of Development Approvals (DAs)

  • Comply with NSW EPA licences (EPLs) and POEO Act obligations

  • Support remediation or contaminated land investigations

  • Protect nearby communities and sensitive environments

  • Demonstrate environmental performance and due diligence

Q: What types of environmental monitoring are commonly required?

Monitoring programs are tailored to the project and site but often include:

  • Groundwater and surface water quality testing

  • Air quality and dust (PM10, TSP, RCS)

  • Noise and vibration monitoring during construction

  • Soil contamination and acid sulfate soil sampling

  • Soil vapour and landfill gas (e.g. VOCs, methane)

  • Post-remediation and validation monitoring

Q: Who requires or enforces environmental monitoring in NSW?

Environmental monitoring may be required by:

  • Local councils as part of DA conditions

  • The NSW Environment Protection Authority (EPA) under an Environmental Protection Licence (EPL)

  • Certifiers and planners for development or subdivision works

  • Landowners, developers, or financiers undertaking due diligence

  • Contractors and operators managing sensitive or high-risk sites

Q: How often should environmental monitoring be carried out?

Monitoring frequency depends on the site’s risk profile, regulatory requirements, and stage of works. Common schedules include:

  • Monthly or quarterly for operational sites or licence compliance

  • Rainfall-event or construction-phase monitoring for CEMP/OEMP plans

  • One-off baseline or validation sampling for due diligence or remediation

  • Real-time or continuous monitoring in sensitive or high-risk areas

We customise each program based on your approval conditions and site needs.

Q: What happens if monitoring results exceed regulatory limits?

If environmental parameters exceed guideline or licence limits:

  • The exceedance must be reported to the relevant authority (e.g. EPA, council)

  • An investigation may be required to determine the cause

  • Corrective actions, such as dust suppression, treatment, or containment, may be implemented

  • Ongoing monitoring or updates to your environmental management plan (EMP/CEMP) may be needed

We assist with incident response, reporting, and communication with regulators.

Q: Can Confluence Environmental help with compliance reporting?

Yes. We provide:

  • Site-specific monitoring programs aligned with DA or EPL conditions

  • NATA-accredited laboratory analysis and field testing

  • Clear, regulator-ready reports with trend analysis and compliance commentary

  • Support for Annual Environmental Monitoring Reports (AEMRs)

  • Advice on next steps if exceedances occur or if additional action is needed
