Contaminated Land Sites Remediation

Contaminated site remediation ensures that hazardous chemicals released into the environment are removed and/or treated via proven remedial technologies and management practices. Remediation planning is critical to ensure that remedial projects are in compliance with permitting requirements, are within budget, and completed on schedule. 

Columbia Environmental has successfully managed numerous small and large scale remediation projects to completion, providing technical support for the cleanup of several abandoned mine sites, landfills, former military ranges, gas stations, rail lines, wood treatment facilities, and a distant early warning (DEW) site. Remediation planning begins with a review of all existing site information, ensuring no data gaps are found, minimizing the potential for projects delays and costly overruns. Based on the results of these reviews Columbia may prepare Remedial Options Evaluations (ROE), Remedial Action Plans (RAP); and finally tendering documents.

The remediation of contaminated sites is generally completed using a Remedial Options Evaluation (ROE) framework which includes assessing site remedial activities through selecting, implementing, and evaluating the available remediation options. Preferred methods of remediation are selected using a weighting system in an evaluation matrix including, but not limited to, technical feasibility, cost, schedule, and regulatory compliance to determine the most suitable or appropriate remedial strategy for a unique site under specific conditions.

The objective of a Remedial Action Plan (RAP) is to implement recommended actions and measure progress of restoration and protection efforts in the Area of Concern to ensure the local goals have been met with regard to future use of the site, time frame, regulatory context, socio-economic benefits, and costs.
