HYDROGEOLOGICAL ASSESSMENTS

LWRC provides specialist hydrogeological investigations and groundwater advisory services in support of environmental approvals (EIA’s, WUL’s), ESG-aligned developments, mining operations, infrastructure projects, industrial activities, and water-resource management initiatives across Africa. Our assessments are undertaken in accordance with internationally recognised hydrogeological best practice principles, regulatory frameworks, and client-specific environmental and operational requirements. We follow a risk-based source–pathway–receptor approach to identify, assess, and manage potential groundwater-related impacts within the local and regional environment.

LWRC combines practical field investigations with advanced technical analyses to develop defensible hydrogeological conceptual models and support informed environmental, operational, and ESG-related decision-making. Our investigations are aligned with project programmes and regulatory timelines to assist clients in reducing approval risk and maintaining efficient project delivery.

Depending on project scope and site-specific requirements, our hydrogeological services may include:

  • Hydrocensus and borehole surveys
  • Geophysical investigations (electrical resistivity, electromagnetic and magnetic surveys)
  • Borehole siting, drilling supervision, and aquifer testing
  • Packer testing and hydraulic characterisation
  • Baseline groundwater investigations and greenfield assessments
  • Groundwater impact and risk assessments
  • Mine dewatering and water management assessments
  • Numerical groundwater flow and contaminant transport modelling
  • Groundwater remediation and mitigation support
  • Hydrochemical and geochemical investigations
  • Hydropedological investigations and soil-water interaction assessments
  • Groundwater monitoring programme design and interpretation
  • GIS-based hydrogeological mapping and spatial analysis
  • Water and salt balance assessments
  • ESG and sustainability-driven groundwater risk evaluations

LWRC focuses on delivering technically robust, practical, and programme-aligned hydrogeological support tailored to the operational, environmental, regulatory, and sustainability requirements of each project. LWRC’s hydrogeological assessments and specialist reports are compiled in accordance with applicable National Water Act (NWA) and Environmental Impact Assessment (EIA) regulatory requirements, including relevant GNR and specialist reporting guidelines.

Early Groundwater Screening for EIA & WUL Programmes

LWRC provides early-stage groundwater screening reports shortly after appointment to help EAPs, engineers, and project teams identify groundwater-related risks before applications are locked into programme.

This upfront input is particularly valuable because EIA and WUL processes are time-sensitive, with prescribed public participation periods, specialist study requirements, authority review periods, and potential requests for additional information. Early groundwater screening helps avoid late-stage technical surprises that can delay submissions or weaken application quality.

Our early screening reports assist with:

  • Identifying groundwater sensitivities, receptors, and potential impact pathways
  • Confirming likely Section 21 water-use triggers and specialist study requirements
  • Defining whether fieldwork, drilling, pump testing, modelling, or monitoring is required
  • Supporting realistic project timelines and scope planning
  • Providing early input into EIA, WUL, IWWMP, and ESG-related project planning
  • Reducing approval risk through proactive, technically defensible groundwater input

LWRC’s approach allows groundwater issues to be identified early, scoped correctly, and integrated into the broader environmental application process — helping clients maintain programme-aligned submissions and avoid unnecessary delays.

In summary, our hydrogeological assessments may include:

  • Hydrocensus and borehole surveys
  • Geophysical Surveys (electrical resistivity, EM, magnetic etc)
  • Borehole drilling and supervision
  • Aquifer testing including packer tests
  • Baseline Investigations / Greenfields
  • Groundwater Impact Assessments
  • Mine dewatering
  • Numerical Groundwater Flow and Transport Models
