Geoenvironmental Services
Managing ground risk, unlocking development value, and delivering compliant, sustainable sites across the UK
Arthian’s Geoenvironmental team helps clients understand, assess, and manage environmental risks in land and groundwater so development can proceed safely, sustainably, and in full regulatory compliance. We combine environmental scientists, chemical engineers, geologists, and contaminated land specialists into a single multidisciplinary team — giving you a holistic, planning‑ready assessment from the outset.
Whether you’re progressing a brownfield redevelopment, discharging planning conditions, or managing complex contamination, we provide the clarity, evidence, and technical assurance needed to move projects forward with confidence.
Why Choose Arthian?
A genuinely multidisciplinary team — environmental consultants, chemical/environmental engineers, geologists, hydrogeologists, and regulatory specialists working as one.
Planning‑aligned reporting — structured to meet the expectations of the EA, NRW, SEPA, NIEA, and local authorities.
Integrated geotechnical + geoenvironmental capability — reducing duplication, cost, and programme risk.
Clear, pragmatic advice — not just data, but actionable pathways to unlock development.
National coverage with rapid mobilisation — supporting projects from small infill plots to major regeneration schemes.
Our Geoenvironmental Services
Phase 1 Desk Study (Preliminary Risk Assessment)
A robust Phase 1 PRA establishes the conceptual site model (CSM) and identifies potential pollutant linkages before intrusive work begins.
Our service includes:
- Historical mapping and land‑use review
- Environmental database screening
- Site walkover and preliminary CSM
- Planning‑ready reporting aligned with BS 10175 and LCRM
Phase 2 Intrusive Investigation
We design and deliver targeted intrusive investigations to confirm ground conditions, contamination, and risk pathways.
Typical scope:
- Soil, groundwater, and gas sampling
- Boreholes, trial pits, window sampling
- Ground gas and vapour monitoring
- Laboratory chemical analysis
- Updated CSM and risk assessment
Contaminated Land Risk Assessment
We undertake detailed quantitative and qualitative risk assessments to support planning, development, and regulatory compliance.
Our assessments cover:
- Human health risk
- Controlled waters
- Ground gas and vapour
- Waste classification and materials management
- Remediation requirements and regulatory engagement
Remediation Strategy & Verification
Where contamination is identified, we develop proportionate, cost‑effective remediation strategies that satisfy regulators and minimise programme delays.
We provide:
- Options appraisal and remediation design
- Materials management plans (CL:AIRE)
- Waste minimisation and sustainability assessments
- Contractor tender support
- Verification and validation reporting
Brownfield Redevelopment Support
We support developers, planners, and landowners through the full lifecycle of brownfield regeneration.
Services include:
- Pre‑acquisition due diligence
- Feasibility studies
- Planning condition discharge
- Integrated geotechnical + geoenvironmental assessments
- Regulator liaison and technical negotiation
Waste Classification & Materials Management
We help clients manage soils and materials efficiently and compliantly.
- Waste Acceptance Criteria (WAC) testing
- Soil classification (hazardous / non‑hazardous)
- CL:AIRE MMPs and DoWCoP compliance
- Reuse, recycling, and disposal strategies
