A master\u2019s thesis of the Danish Tech.

Also, the diffusion rate through water is 1\/10,000 of that in air for TCE, so it is a slow process. The long-term emplacement of several weeks is many orders of magnitude longer than the exposure to the borehole water. The carbon felt is also isolated from the carrier liner with a diffusion barrier.   <\/p>\n<p>&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; parentOrderClass=&#8221;dsm_faq_0&#8243;][\/dsm_faq_child][dsm_faq_child dsm_title=&#8221;Will the borehole water affect the contaminant distribution in the hole wall material?&#8221; dsm_content=&#8221;<\/p>\n<p><strong>Yes<\/strong>, if the borehole water is contaminated or not contaminated. However, the recommendation is that the borehole be sealed with the Flute liner and FACT system immediately after the hole is drilled and developed. Due to the slow diffusion rate of many contaminants through water, the borehole water exposure should have only a small effect on the pore water. The FACT in 2 weeks\u2019 time is expected to draw contamination from several centimetres in the borehole wall depending upon the porosity of the formation or fracture volumes. Very high contamination of the borehole water may produce a relatively uniform background everywhere in the hole wall. A rapid drilling method such as air rotary should help to reduce that exposure.     <\/p>\n<p>&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; parentOrderClass=&#8221;dsm_faq_0&#8243;][\/dsm_faq_child][dsm_faq_child dsm_title=&#8221;Is the carbon concentration of contaminant a direct measure of the contaminant in place?&#8221; dsm_content=&#8221;<\/p>\n<p><strong>No.<\/strong> The carbon contamination is measured as grams of contaminant per gram of carbon. The level of contamination in the carbon is proportional to the diffusion coefficient for the contaminant and the concentration gradient between the formation pore space and the carbon. The initial carbon concentration is zero. The carbon concentration should be a relative measure of the<br \/>availability of the contaminant in the formation.   <\/p>\n<p>&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; parentOrderClass=&#8221;dsm_faq_0&#8243;][\/dsm_faq_child][dsm_faq_child dsm_title=&#8221;How is the FACT analysed?&#8221; dsm_content=&#8221;<\/p>\n<p>The usual method is to section the carbon, submerge it in methanol to extract the VOCs and to analyse the methanol in a GCMS.
