ISC - Groundwater Remediation Services

Soil and groundwater contamination are relatively common. Much of the cost associated with a remediation system is a function of the remediation system design. There is a onetime capital cost associated with new equipment, and there is a continual recurring operation and maintenance (O M) cost. The remediation method selected has a significant effect on O M cost. Treatment methods, such as carbon and resin beds, typically have a low capital cost, but a high O M cost however, regardless of the remediation system selected, a good design can minimize unnecessary O M costs. Typically, site visits are necessary to record data and collect samples to evaluate remediation system progress. If inexpensive preventive maintenance is not conducted, costly, major corrective maintenance may be required later.

Remediation systems include: air strippers; oil/water separators; vacuum extraction systems; catalytic and thermal incinerators; carbon beds; air sparging systems; and biological treatment systems.

ISC’s Specific tasks include:

• Performance of groundwater quality and hydro geologic characterizations of the site and adjacent areas;
• Assessments of the extent and magnitude of off-site contamination;
• Numerical modeling of the groundwater flow system to determine the hydraulic effectiveness of remediation;
• Preparation of QA/QC plans for collection of water samples and the installation of monitoring wells;
• Development of health and safety plans for drilling and sampling;
• Performance of a floodplain encroachment investigation;
• Determination of the effectiveness of monitoring well purging during sampling;
• Preparation of drilling specifications; and
• Performance of groundwater, surface water, and soil assessments at the facility.

ISC has been teaming with one of most advanced groundwater remediation solution companies in Canada, Vertex Environmental Solutions Inc. offers clients a wide suite of in-situ technologies including ISCO, ISCR and enhanced bioremediation which allows Vertex to apply the best treatment to remedy the problem.
