With the increased cost of disposing of contaminated soils Southern Ground Testing are frequently called on the carry out in situ remediation of soils. The technique involves the driving of a perforated cone with a hydraulic valve into the ground using pecussive drilling as shown above and below. A mix of the desired agent such as oxygen releasing compound (ORC) or hydrogen releasing compound (HRC) is pumped into the ground using a hydraulic hopper.
In the case of ORC, the bacteria naturally occurring in the ground are activated into consuming any hydrocarbon contamination within the soil. For full analysis of this technique please refer to www.regenesis.com.
