Remediation of Contaminated Land for Urban Redevelopment

Overview

A former industrial site, previously used for manufacturing and chemical storage, was identified as a prime location for a mixed-use redevelopment project. However, extensive soil and groundwater contamination posed serious environmental and health risks. BHM Geotechnical was tasked with implementing comprehensive site investigations and strategic remediation efforts to restore the land for commercial and residential development.

The Challenge

• Industrial Contamination: The site was polluted with heavy metals and hydrocarbons.
• Groundwater Risks: Toxic elements had migrated, threatening water safety.
• Regulatory Compliance: Strict environmental guidelines required thorough remediation before development.

Our Approach

A structured geotechnical assessment and remediation strategy were implemented:

1. Detailed Site Investigation

• BHM Geotechnical conducted Phase 2 assessments, including soil and groundwater sampling.
• Laboratory analysis identified contamination levels and pollutant distribution.
• Risk assessments ensured an effective remediation plan tailored to the site’s needs.

2. Remediation Strategy

• Excavation & Bioremediation: Contaminated soil was removed and treated using microorganism-based degradation.
• Groundwater Extraction & Filtration: Advanced filtration and chemical oxidation neutralized pollutants.
• Ongoing Monitoring: Continuous assessment confirmed successful decontamination.

3. Safety and Environmental Protection

• Containment measures prevented further contamination spread.
• Dust control and safety protocols minimized risks during excavation.
• Community engagement efforts addressed public concerns about environmental safety.

The Solution

Our approach combined advanced remediation methods with strict environmental oversight. The site was restored, paving the way for safe, compliant redevelopment.

• Structural Stability: Bioremediation techniques eliminated hazardous substances.
• Water Quality Restoration: Filtration systems ensured groundwater met safety standards.
• Regulatory Approval: Final assessments confirmed compliance for redevelopment.

Results and Impact

The project turned a polluted site into a safe, useful space for homes and businesses. It helped protect the environment and brought new opportunities to the local community.

• Sustainable Urban Development: A once-polluted site was transformed into a vibrant, mixed-use space.
• Environmental Safety: The project upheld high environmental protection standards.
• Economic Growth: The redevelopment boosted local business and housing opportunities.

Conclusion

This case study showcases how BHM Geotechnical’s expertise in geotechnical and environmental remediation successfully transformed contaminated land into a safe and sustainable urban development. Through strategic planning, innovative remediation techniques, and ongoing monitoring, the site was restored, unlocking new opportunities for commercial and residential growth.
