Green & Sustainable Remediation
GSR involves quantifying the secondary effects or unintended environmental impacts of soil and groundwater remediation on the environment and taking steps to minimize these effects while meeting the regulatory and other requirements governing that remedy. Many companies today have implemented environmental management systems and recognize corporate social responsibility management concepts that integrate social and environmental concerns into their business operations. The intent of the GSR approach is to reduce and minimize the environmental footprint of the ongoing remediation project, recognizing that valuable resources are consumed in the execution of this work.
Versar is committed to using GSR practices in the execution all of our projects and tracks and reports our progress using industry-standard tools as appropriate to meet project-specific goals and objectives. Our objectives are to:
- Reduce fuel consumption and transportation costs as a result of integrated "dig and haul" planning with fewer field mobilizations, planned traffic routes, and understanding peak use times.
- Reduce greenhouse gas emissions through use of renewable resources to provide electricity for auxiliary equipment such as solar recharge options or replacement of natural gas-driven equipment.
- Reuse all suitable gray water or water from dewatering operations like land application such as irrigation, recharge ponds, or infiltration galleries, or discharge to surface waters.
- Track and report percentage of excavated clean soil or other material suitably reused onsite.
- Replace/restore ground cover soon after excavation with recovered native species and increase use of permeable materials such as permeable pavements for parking and sidewalks.
- Quantify and report increases in permeable surfaces.
- Incorporate the use of EPA's low impact development techniques for stormwater management (earth dikes and swales); site restoration; drainage improvements;, and green infrastructure to leave sites in a better, "greener" condition than they existed before our arrival.
