Soil contamination is caused by the presence of chemical alternations in the ground.

Soil contamination results from the rupture of storage tanks, application of pesticides, percolation of contaminated surface water, oil and fuel dumping, and the discharge of wastes from landfills. The most common chemicals involved include petroleum hydrocarbons, pesticides, solvents, lead and other metals.

The concern over soil contamination stems primarily from health risks, from direct contact with the soil and soil dust, vapors from the contaminants, and from secondary exposure through water underlying the soil. 

A solution to soil contamination is soil remediation. Soil remediation is a way of purifying and revitalizing the soil by removing contaminants to protect both the health of the population and the environment. The goal of this process is to restore the soil to its natural, pollution-free state. 

Cleanup or remediation of soil contaminants is analyzed and performed by workers within the environmental industry. There are several principal strategies for remediation:

  • Aeration of soils at the contaminated site
  • Thermal remediation to volatize chemical contaminants
  • Bioremediation techniques, like landfarming or bio-stimulation
  • Extraction of groundwater or soil vapor
  • Containment of soil contaminant

However, prior to soil remediation, properly surveying the soil’s condition is vital to understanding the risks associated. During this process, gas detection equipment can help detect and monitor the present containment within the soil and the ground surrounding it.  

GasClam, from ION Science, is a unique in-borehole gas monitoring system developed for the unattended collection of long-term, real-trend soil and ground gas data. GasClam collected continuous ground gas and chemical concentration data, as well as parameters that are known to control it such as subsurface pressure, atmospheric pressure and water level.
