Traditional remediation approaches often focus on reducing the contaminant levels to the risk-based levels at low cost in a short period of time. In contrast to a traditional remediation approach, green and sustainable remediation (GSR) is a holistic approach to remediation that also minimizes ancillary environmental impacts. The GSR approach addresses a broad range of environmental factors and community impacts during all remediation phases. The objectives of GSR aim to achieve remedial goals through more efficient, sustainable strategies that conserve resources and protect air, water, and soil quality through reduced emissions and other waste burdens. GSR also simultaneously encourages the reuse of remediated land and increased longterm financial returns for investments. Ultimately, the GSR approach strives to maximize the environmental, social and economic benefits (often known as triple bottom line) associated with a project. Though the potential benefits of GSR are enormous, many environmental professionals and project stakeholders do not utilize GSR technologies because they are unaware of methods for selection and implementation. However, with continued public awareness of sustainability issues, GSR will increasingly be pursued. This study provides an overview of the elements of GSR, a review of initiatives to foster GSR best management practices, a summary of metrics to assess the sustainability of GSR, and a review of selected case studies that highlight the net environmental, economic, and societal benefits of incorporating GSR for site restoration.
