Soil and groundwater sampling is a necessary step of developing on potentially contaminated land. These processes reveal any hazardous waste in the area that could delay a construction project, but they don’t always make the site unsuitable. Contractors use advanced methods to remove contaminants and reduce their impact on the environment and human activity. The specific remediation method depends on the topography and type of contaminants, and below are several important parts of testing.

What Does the Hazardous Waste Removal Process Include?

1. Test the Location

Comprehensive testing for hazardous waste may include groundwater sampling and an investigation of the soil. Environmental engineers take several samples from the area to a lab, where they can thoroughly research the conditions. This can reveal and measure levels of arsenic, chemical pollution, and even radioactive compounds.

For example, one way researchers get samples is with a membrane interface probe. This device measures chlorine levels without disturbing the surface layer. Some professionals may even have mobile gas chromatography equipment that allows them to conduct detailed soil analysis on-site.

2. Perform Feasibility Studies & Risk Assessment

After testing, your geoscientists will perform risk assessment studies attempt to estimate whether the levels of contaminants are dangerous for humans or the environment. Depending on the results of the soil and groundwater sampling, the assessment may determine that the site is safe to use without remediation.

However, if the risks are high, you will need to conduct a feasibility study to determine the best remediation method. Contaminant mitigation professionals have a variety of techniques at their disposal, with each one working better depending on the toxic materials present.

3. Begin Hazardous Waste Remediation

If the contamination is relatively minor, the geoscientists may start treating the hazardous conditions on-site, usually by being flushing them out with water or chemicals that negate the toxic materials. Your engineer may also recommend burning the area or introducing natural organisms that will break down the contaminants.

If you’re dealing with radioactive material or working close to a watershed, completely removing the affected soil may be the best approach. Your contractor will excavate the topsoil and take it for treatment off-site. Then, they will replace the dirt with clean soil.
