Rule Engineering provides site assessment and remediation services drawing on a strong experience base in applying innovative technological strategies and sound scientific principles to develop solutions to environmental contamination problems. Our specialty is applying Risk-Based Corrective Action (RBCA) strategies beginning in early scoping of the site conceptual model to focus not only the remediation but the site assessment to manage actual or potential risks at the site. Rule has provided technical services in site assessment and remediation to a wide variety of sectors in the oil and gas industry including E&P, pipeline and transportation, refining, and retail marketing sites. Our experience working at this broad spectrum of facilities in various subsurface conditions has resulted in the successful closure of many contaminated sites that has resulted in repeat business from our clients recognizing our focus on saving money and eliminating liabilities from their bottom line.
The range of site assessment technologies that have been applied by Rule’s principals and staff include:
The range of remediation technologies that have been successfully applied include:
Our capabilities include state-of-the-art data management, visualization, and modeling software, as well as GIS and CAD programs.
E&P Groundwater Remediation
Western ColoradoSee More
Groundwater contamination due to migration from a natural gas well along natural fractures resulted in exceedances of benzene and methane in surface water and groundwater. After several years of operating a sparge system with little progress, Rule was selected to provide remediation for the site. Our evaluation...
E&P Tank Closures
Northwestern ColoradoSee More
Closures were completed on over 70 produced water holding tanks covering a large area in a remote part of northwestern Colorado. The replacement of the existing culvert pit holding tanks was coordinated with the oil and gas operator to install above-ground tanks with minimal downtime. The tanks and impacted soil...
UST Remediation AS/SVE System
Denver Metro Area, ColoradoSee More
An air sparge/soil vapor extraction (AS/SVE) remediation system was designed based on pilot test data. A total of 6 AS wells and 5 SVE wells were to remediate gasoline constituents in the groundwater by directly volatilizing the constituents and supplying oxygen for aerobic biodegradation. The work included prep...
UST Remediation LNAPL Multiphase System
Denver Metro Area, ColoradoSee More
A multiphase extraction system was designed to address an extensive LNAPL plume spanning multiple off-site properties to dewater the upper low-permeability zone and allow product recovery and vapor extraction in the sand units where the NAPL was trapped. Based on extensive aquifer testing and site characterizati...
Refinery Groundwater Containment System
A containment system was designed under a Consent Order with the WDEQ to prevent off-site migration of contaminated groundwater and LNAPL. An alternative evaluation design was used to select a soil bentonite slurry wall with a series of interceptor. Data from a detailed subsurface investigation was used to desig...
Refinery Groundwater Modeling
A groundwater model was developed to address corrective actions under the WDEQ to provide an understanding of remedial alternatives to prevent off-site migration of contaminated groundwater and LNAPL. A three-dimensional finite-difference groundwater model was used to assist with the design and placement of a gro...
