Soil/Groundwater Contamination Detection & Mapping

AGL carries out investigations to define and delineate contaminants present and the vertical and lateral extent of contamination of a site. We integrate geophysics, stratigraphy, sedimentology and geochemistry to evaluate a contaminated site. First of all, geophysical and passive soil vapor surveys (using the Amplified Geochemical ImagingTM technology) are used to identify the “hot spots” of the site, and thus act as tools to optimize the locations of boreholes so that the site can be efficiently characterized. The potential for contaminant migration is evaluated using the physical and chemical properties of the contaminants and soil. We also undertake an assessment of risk exposure on human health and environment, and cost-benefit analyses of all applicable remedial approaches to clean-up.

These are done with consideration to cost while maximizing geophysical data quality.

Anthropogenic Land Subsidence Prediction

Land subsidence is used to indicate the lowering of the ground surface. It is a familiar follow-up phenomenon of a variety of natural events that add up to the geologic history of many areas such as the deltas. Studies have revealed it is greater when the geological processes (e.g. compaction) are set in motion or accelerated by man’s engineering activities such as fluids (e.g. oil and gas) withdrawal from the subsurface. 
The consequences of subsidence in coastal areas are similar to sea-level rise, and include:  

  • Increased coastal flooding
  • Degradation of the groundwater quality of coastal aquifers     
  • Loss of fresh water ecosystem through salinization
  •  Reactivation of faults
  • Failure of man-made structures 
AGL has the expertise to model and monitor compaction and the consequent subsidence of oil fields, and recommend remedial actions. Proactive management is the only way land subsidence can be managed.

AGL is committed to creating economic value, but mindful of the way it is done. Therefore, it is the company’s commitment to provide a safe work environment both in our offices and field.

Our commitment to HSE is ‘bed-rocked’ on the following basic principles:
•All accidents/injuries are preventable;
•The protection of life and health at work is a fundamental worker’s right. Workers have a duty to take care of their own safety as well as the safety of anyone who might be affected by what they do or fail to do;
•Information is important for development and implementation of effective HSE programmes. The collection and dissemination of accurate information on environmental/job hazards and hazardous materials, surveillance of work places, monitoring of compliance with policies and good work practices;

•Workers and management have certain responsibilities, duties and obligations. For example, workers must follow established safety procedures; management must provide safe work places, PPE’s and ensure access to medical facilities;

•Environmental protection must be enforced through the application of sustainable environmental practices in project planning and execution.

Job trainings, pre-work inductions, inspections, audits and HSE meetings are avenues used by AGL for communication of hazards, unsafe acts etc.
HSE performance indicators are continually monitored and statistics updated. Corrective actions are taken to keep statistics at manageable levels. For example, incidents are categorized by their degree of impact, this forming the basis of follow-up as in notification, investigation, analysis, lesson learning and improvement.
