Groundwater & Surface Water Monitoring
Expert monitoring of groundwater and surface water — helping you manage risk and meet environmental obligations.
Why Monitor Groundwater and Surface Water?
Monitoring surface water and groundwater is critical for:
Development approvals and DAs
Remediation and contaminated land projects
EPA licence and POEO Act compliance
Resource recovery and waste classification
Baseline and impact assessments
Industrial and infrastructure operations
Acid sulfate soil and salinity risk management
Whether it’s to satisfy consent conditions, investigate contamination, or demonstrate compliance, our consultants deliver data you can trust — and advice you can act on.
Our Water Monitoring Services
We tailor every program to your site, risks, and regulatory needs, offering:
Groundwater Monitoring
Installation and gauging of monitoring wells (bores)
Purging and low-flow sampling techniques
Field parameters (pH, EC, DO, redox, turbidity, temperature)
Laboratory analysis of heavy metals, nutrients, hydrocarbons, PFAS, and more
Depth to groundwater and seasonal variation tracking
Contaminant plume assessment and delineation
Groundwater quality compared against NEPM (ASC) and ANZG Guidelines
Used in planning approvals, landfill/leachate assessments, remediation, fuel site investigations, and baseline studies.
Surface Water Monitoring
Creek, stormwater, wetland, and catchment sampling
Flow conditions, aquatic ecology, and riparian considerations
Sediment and water quality sampling
Field measurements and NATA-accredited lab analysis
Comparisons against ANZG 2018 Guidelines, local water quality objectives, or licence limits
Impact monitoring for developments near sensitive waterways or wetlands
Used for EPA monitoring programs, stormwater assessments, biodiversity offsets, and site runoff control.
Regulatory & Compliance Reporting
Environmental Protection Licence (EPL) compliance
POEO Act and local consent condition reporting
Ongoing monitoring and annual return programs
Baseline reporting and development risk assessments
Contaminated land and remediation verification
We prepare clear, audit-ready reports for submission to NSW EPA, councils, or certifiers — aligned with relevant guidelines and decision frameworks.

Frequently Asked Questions (FAQ) - Groundwater & Surface Water Monitoring
Why is groundwater and surface water monitoring important?
Monitoring helps detect and manage environmental risks early. It supports:
Early identification of groundwater or surface water contamination from industrial, urban, or agricultural sources
Protection of sensitive ecosystems, aquatic life, and drinking water supplies
Compliance with NSW environmental regulations, including EPA licence conditions, planning approvals, and the Protection of the Environment Operations Act 1997 (POEO Act)
Baseline data collection before development or remediation activities
What are the common sources of water contamination?
Typical causes of water quality impacts in NSW include:
Leaking underground petroleum storage systems (UPSS), especially at fuel stations
Chemical spills or discharges from industrial sites
Stormwater runoff carrying sediment, nutrients, pesticides, or hydrocarbons
Landfill leachate or contaminated fill material
Disturbance of acid sulfate soils, releasing sulfuric compounds into water systems
How often should water quality monitoring be conducted?
Monitoring frequency depends on your site’s regulatory requirements, contamination risk, and project phase. Common scenarios include:
Quarterly or annual sampling for routine environmental compliance or long-term site monitoring
Monthly or rainfall-triggered sampling for high-risk sites or active remediation areas
Short-term intensive programs for due diligence, development approvals, or baseline studies
We tailor every monitoring program to suit your site's conditions and obligations.
What happens if contamination is detected in groundwater or surface water?
If results show elevated levels of pollutants (e.g. heavy metals, hydrocarbons, nutrients):
A Detailed Site Investigation (DSI) may be required to define the extent and risk
A Remediation Action Plan (RAP) may be developed to address contamination
Ongoing water monitoring and reporting is usually required to track progress and ensure regulatory compliance
Confluence Environmental can guide you through each step of this process.
Can Confluence Environmental help with EPA and council compliance?
Absolutely. We offer:
Site-specific water monitoring programs
Sampling and laboratory analysis using approved methods
Regulatory reporting suitable for NSW EPA, local councils, and water authorities
Expert guidance on interpreting results and managing environmental obligations
Our team ensures you stay compliant — and avoid costly delays, penalties, or remediation missteps.
