Mr Henning Steenberg got in contact with Craggs Environmental after his domestic heating oil tank spilt causing 200L – 500L to seep into his front garden. Craggs Environmental uplifted the remaining contents from the tank and then ensured there was no further contamination in the ground.
Craggs Environmental began work hand digging the contaminated soil this was the best cause of action to the level that we had to go to, 4 tonnes originally quoted to remove in both soil & existing concrete pad. Further PID sweeps were taken whilst we were excavating to understand the level of contamination and ensure contaminants were still present. On the east side of the excavation at around 1.2m depth we discovered an area of soil with excessive PID readings of around 1400-1500ppm, PID readings either side of this area are slightly elevated but not high enough to indicate excessive contamination. Craggs Environmental also removed and disposed of the failed tank.
Before backfilling took place the guys tested the ground and the volume of contamination increased from what was originally thought, we trial pitted down to 900mm underneath the concrete base and still found high VOC concentrations. Further excavation was carried out at site, until the level of contamination was at a safe level, upon completion of this we backfilled the area and reinstated the concrete pad for the tank.
After completing the work Craggs environmental removed one oil tank and excavated around 5 tonnes of contaminated soil and concrete slabs. Mr Steenberg was happy with the work that we did making his house and the environment safe.
