Project Detail:
Ensolum operates and maintains a group of combination air sparge (AS) and soil vapor extraction (SVE) and AS-only remediation system trailers owned by the client and deployed throughout the Denver-Jules (DJ) Basin. The client-owned trailers have been in service for approximately 15 years and are rotated throughout the portfolio of groundwater remediation sites as new candidates for remediation via AS/SVE are identified. This leads to a long-term and cost-effective remedy across the portfolio.
Feasibility studies are performed using site-specific and industry-specific knowledge and/or site-specific pilot test data to evaluate sites for active remediation via AS/SVE. Any necessary permits required for operation are procured prior to installation, including air and underground injection control permits and any building permits required by the municipality or county. Ensolum’s engineering team designs the system layouts and coordinates the installation of all aspects of the system, including AS/SVE well installation, trenching), piping installation, and final connections to the trailer.
Operations and maintenance (O&M) is performed biweekly by field technicians to evaluate performance, make adjustments as necessary, and perform routine maintenance work including, but not limited to, blower belt tensioning, oil changes, lubrication, and filter replacement. Data is reviewed by engineering staff on a monthly basis to evaluate whether modifications and adjustments are necessary to maximize performance accordingly.
All necessary parts are procured by Ensolum personnel, and electricians are subcontracted on an as-needed basis to aid in the repairs of aging equipment. Monthly system updates are provided to the client and include information on runtime, modifications to operation, and any recommendations for future operation.
Air samples are taken quarterly by field technicians or as directed by the applicable air permit for each site for laboratory analysis, and the engineering staff performs mass removal and emissions calculations to ensure permit compliance. Regulatory reports summarizing system performance and recommendations are prepared and submitted by Ensolum personnel following client review and approval. Following the discovery of historical soil impacts during construction activities at an inactive upstream oil and gas facility, soil and groundwater delineation activities were performed, and a monitoring well network was installed at the site.
