Oil Spills on Land
Since oil was discovered, fuel and oils spills have been contaminating millions of acres of land rendering them useless. Until now, the best treatment was to excavate the soil and burn it, which is costly and unnecessary. DE-OIL-IT safely removes grease, fuel and oil spills from the soil – 100%.
By saturating the contaminated soil with DE-OIL-IT it will float the oil to the surface from varying depths, depending on the type of soil. This makes it possible to skim the oil off, alternatively it will break the oil down sufficiently to make it biodegradable, just as it does when used as a degrader on oil spills at sea.
For spills, which are deeper in the soil, in-site injection techniques can be used to feed the degrader mixture to the required depth.
Remediation of hydrocarbons fromsoil without excavation
Oil Spills on Land Process Overview
- Initial investigative work identifies the specific area(s) of impact.
- Boreholes are constructed in the hydrocarbon contaminated site as well as down gradient from it. The newly constructed boreholes are utilized to administer the proposed remediation process
- The remedial liquid is gravity fed into the impacted area beginning in the source area followed by the down gradient portions of the plume. Environmental monitoring occurs throughout the process in order to chart the degree of remediation occurring and to compare the results with the appropriate criteria.
- Boreholes are constructed at the site for initial plume definition by an independent environmental consulting firm. Subsequent liquid feed and monitoring boreholes are located in a systematic manner by Trinidad Tank & Fuel.
- Soil samples for plume delineation and subsequent monitoring are taken from appropriate borehole locations and submitted to a recognized laboratory for analysis. These will include total petroleum hydrocarbons (TPH) and Benzene, Toluene, Ethyl Benzene and Xylenes (BETX) and other parameters requested by Trinidad Tank & Fuel or by the local environmental authority criteria.
- Following the receipt of the initial soil analytical results, the remedial liquid is prepared and gravity fed into the boreholes at the site and in a manner that does not interfere with ongoing business activities.
- In most cases, 21 – 35 days after the start of the remediation process, soil samples are collected from the treatment area, by an independent environmental consulting firm and submitted to an appropriate analytical laboratory for analysis of Trinidad Tank & Fuel network parameters. These interim samples confirm the rate of hydrocarbon degeneration and establish a remediation time line.
- In most cases, 60 days after the initial injection, another set of samples are collected by an environmental consulting firm and submitted to a recognized laboratory for TPH and BETX analysis. This final procedure confirms the effectiveness of the remedial process by the comparison of the results to the applicable remediation guidelines. This information is compiled in an analytical report by an environmental consultant and submitted to the appropriate regulatory agency for their review. Upon the completion of the soil remediation process, Trinidad Tank & Fuel closes all boreholes and restores them to the original grade in an environmentally responsible manner.
