Studies & Assessments

Technical scientific assessments required for planning and licensing support — from geohydrology and ecology to waste classification and rehabilitation planning.

Why Specialist Studies Matter

Robust environmental decision-making depends on sound science. Licensing authorities, lenders, and communities increasingly expect applications and management programmes to be underpinned by rigorous, defensible technical studies — not generic assumptions.

Our multidisciplinary team conducts field investigations, laboratory-based analysis, and technical modelling to generate the scientific evidence base your project needs for licensing, compliance, and long-term environmental management.

What We Offer

Our Studies & Assessment Services

GN 704 & Stormwater Assessments

Technical assessments addressing GN 704 requirements under the National Water Act for mining-related activities, including stormwater and clean/dirty water management planning.

Geohydrological Studies

Groundwater assessments to characterise aquifer conditions, assess potential impacts, and inform water use licensing, waste facility siting, and contamination risk management.

Waste Classification & Assessments (NEM:WA)

Laboratory-based classification of waste streams under the National Waste Classification and Management System to determine hazard rating and appropriate disposal routes.

Ecological Assessments

Baseline flora and fauna surveys and impact assessments to inform environmental authorisation applications and support biodiversity management planning.

Integrated Water & Waste Management Plan Development

Development of IWWMPs that align water and waste management practices with regulatory requirements and operational realities.

Water Balances

Site-specific water balance modelling to quantify water inflows, outflows, and storage, supporting licensing applications and operational water management.

Alien & Invasive Plant Control and Management Plans

Assessment and planning support for managing declared alien and invasive species in line with NEMBA requirements.

Vegetation Removal Permits

Applications for permits required to remove protected or listed vegetation ahead of construction or land clearing activities.

GIS and Maps Compilation

Spatial data compilation and mapping to support applications, monitoring, and reporting requirements.

Rehabilitation Strategy & Implementation Programme (RSIP)

Development of rehabilitation strategies and implementation programmes for closure, mine rehabilitation, and land restoration projects.
