Why Site Investigations Matter
Redevelopment, acquisition, or change of land use all come with environmental responsibilities. A robust site investigation helps you:
- Identify potential contamination early
- Avoid costly surprises during construction or acquisition
- Demonstrate due diligence to regulators, investors, and stakeholders
- Understand what remediation or management may be required
- Confirm whether a site is suitable for its intended future use
EGA combines technical expertise with a practical, outcome-driven approach, so you get clear answers rather than just data.
