Soil and groundwater remediation
At a site in northern Indiana on behalf of a multinational client, Troy Risk operated a groundwater remediation system to cleanup the source of chlorinated solvent impact to a groundwater aquifer system. Prior to 1988, the site was occupied by a manufacturing facility. In March 1995, chlorinated volatile compounds (CVOCs) were detected pursuant to due diligence for real estate refinancing. From ...

Alberta Tier 2 Soil and Groundwater Remediation Guidelines
The Alberta Tier 2 guidelines for soil and groundwater remediation are used when considering site-specific conditions implemented through modifying Tier 1 remediation guidelines. It is also applied to remove exposure pathways that do not apply to specific sites. Compared to Tier 2 remediation guidelines, a lot of information about a site is needed to implement Tier 2 guidelines. The required ...

Alberta Tier 1 Soil and Groundwater Remediation Guidelines
The Alberta Tier 1 Soil and Groundwater Remediation Guidelines are developed and updated by Alberta Environment and Parks through the legislative basis provided by the Water Act(Government of Alberta, 2000) and the Environmental Protection and Enhancement Act(Government of Alberta, 2006). The Tier 1 guidelines are generic and were created to protect sites that are found on the more sensitive side ...

The no. 1 choice for improving the performance of soil and groundwater remediation
Adsorption of Contamination The number one challenge associated with most site remediation designs and methodologies is that 90% to 95% of all environmental contaminants; including hydrocarbons (LNAPL), chlorinates (DNAPL), and heavy metals; are present in a sorbed (i.e., absorbed or adsorbed) phase onto soil and bedrock surfaces within both saturated and unsaturated zones. As such, the absorbed ...

In Situ Thermal Remediation of DNAPL and LNAPL Using Resistance Heating
Electrical resistance heating (ERH) is an in situ thermal treatment for soil and groundwater remediation that can reduce the time to clean up volatile organic compounds (VOCs) from years to months. The technology is now mature enough to provide site owners with both performance and financial certainty in their site-closure process. The ability of the technology to remediate soil and groundwater ...

Source area remediation of TCE in soil and groundwater Fort Wayne, Indiana
TRS Group, Inc. (TRS) was retained by Clayton Group Services to perform an Electrical Resistance Heating (ERH) remediation of trichloroethene (TCE) in soil and groundwater. The guaranteed remediation contract required both the baseline TCE mass in soil and groundwater to be reduced by 90% and 1,588,000 kilowatt-hours (kW-hrs) of energy to be applied to the subsurface. TRS was able to input the ...

Electrical Resistance Heating: a Hot New Approach to Soil and Groundwater Remediation
Electrical Resistance Heating (ERH) is an aggressive remediation technology that can quickly reduce the mass of volatile organic compounds (VOCs) in soil and groundwater by over 99%. The process is often used to clean sites where other technologies have had limited success. Larger ERH sites are cleaned within 6 to 12 months and smaller sites can be cleaned in half that time or less. The ...

Chlorinated VOC Groundwater & Soil Remediation - Case Study
Summary Burns & McDonnell was retained to perform soil and groundwater remediation of chlorinated volatile organic compounds (VOCs) such as perchloroethylene and trichloroethylene (PCE and TCE) at a warehouse facility in Dallas. A historical spill of the chlorinated VOCs behind the warehouse building resulted in the contamination of soil in the immediate area and shallow groundwater leading ...

Liberating contaminants for easy recovery
The number one challenge associated with most site remediation designs and methodologies is that 90-95 per cent of all environmental contaminants are present in an adsorbed phase onto soil and bedrock surfaces within both saturated and unsaturated zones. Contaminants, including hydrocarbons (LNAPL), chlorinates (DNAPL) and heavy metals, are sorbed onto the substrates and so have reduced mobility ...

The Phase 1 Environmental Assessment
In today’s world where every property is subject to potential environmental risks a Phase 1 Environmental Site Assessment or ESA is an appropriate action to take. An ESA can help determine if the property has been contaminated by previous or current activities. The ESA can help protect the purchaser of a property from environmental risks prior to the closing on a property. Lenders ...
