  • Contaminated Soil Remediation Works - KDC
    some 300mm to form the development platform An existing stockpile of some 6 500m3 of contaminated soil mixed with concrete brick and metal was identified as a potential development platform material Contamination consisted of total petroleum hydrocarbons of various natures and varying degrees of weathering Hydrocarbon concentrations ranged from 2 000mg kg to around 7 000mg kg The client approached SEPA to enquire if the waste stockpile could be re used in the development platform under the provisions of a Waste Management Licence Exemption KDC provided support for this application and was also commissioned by the principal contractor for the Project to complete the bioremediation works Hazardous Waste Stockpile Chemical analysis results of the soil indicated that petroleum hydrocarbon contamination would classify the material as hazardous waste under the WM2 guidelines The conditions of a Waste Management Licence Exemption prohibit the re use hazardous waste in engineering works for a development As such treatment of the contaminated soil was required to lower the contamination concentrations to a level where the waste could be classified as non hazardous thus enabling its use in the re development Sustainable Options Sustainability analysis indicated that by segregation of the concrete brick and metal from the stockpile the remaining soil could be utilised in the construction of the development platform Suitable hardcore could be crushed and also used in the development platform Remedial Works KDC submitted a Working Plan to SEPA in accordance with the requirements of their Mobile Plant Licence Control measures included the installation of cut off trenches as a contingency to prevent leaching hydrocarbons migrating off site during the bioremediation work KDC also completed the initial physical screening and sorting of the stockpile in conjunction with bioremediation of the fines and soil using a windrowing technique Bioremediation Works All material was successfully

  • Former Gasworks Soil Remediation - KDC
    a rapid delineation exercise which involved excavating a series of strategically placed trial pits across the former gas works processing areas to observe ground conditions collect samples and complete on site rapid hydrocarbon analysis During the delineation exercise contamination was identified using visual observations and a Site Lab Field Hydrocarbon UV Fluorescence Testing System for chemical analysis For this project real time decisions were made giving rapid and increased accuracy of contamination delineation with significant cost savings Our report concluded that some 3 000 tonnes of contaminated material required removal comprising granular made ground sands and river gravels saturated with hydrocarbon products Given the confidence in our findings KDC agreed to warrant the quantities requiring removal Soil Washing The strategy proposed that affected material should be carefully excavated and segregated for transport to an off site soil washing facility This was viewed to be the most practical and sustainable remedial technique under the available budget and timescales The washed material is made available for re use and hence is not subject to associated landfill costs As a contingency a landfill tax exemption had been put in place some of this exemption was utilised for the filter cake from the washing treatment and for some silty clay materials that the soil washing plant could not treat The excavation works were supervised by a KDC Scientist and due to diligent segregation of the materials the total quantity of soil transported off site from the delineated area was some 2 600 tonnes This gave significant cost savings which were passed on to our delighted client Health and Safety Health and safety on site was of paramount importance all personnel required to be in the vicinity of the dig area wore respiratory protection safety glasses disposable coveralls and gloves A decontamination unit was set
