In-Situ Remediation Of Hydrocarbons Without Excavation!

Methodology Overview

  1. Initial investigative work identifies the specific area of impact.
  2. 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.
  3. 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.


Detailed Methodology

  1. 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 Spilltech Environmental.
  2. 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 Spilltech Environmental or by the local environmental authority criteria.
  3. Following the receipt of the initial soil analytical results, the remedial liquid is prepared and gravity fed into the boreholes at the site in a manner that does not interfere with ongoing business activities.
  4. 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 Spilltech Network parameters. These interim samples confirm the rate of hydrocarbon degradation and establish a remediation time line.
  5. 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 via 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, Spilltech closes all boreholes and restores them to the original grade in an environmentally responsible manner.
