The remediation company contacted INJECTIS to focus on low-permeability zones contaminated with chlorinated solvents (PCE, TCE, cis-1,2-DCE) in groundwater.<\/p><p>The site is divided into sub-zones, and the overall objectives are based on a 60% reduction of contaminant mass, with target concentrations of chlorinated solvents below 100 \u00b5g\/L. The technical approaches for each zone were developed by the remediation company. Prior to injection, pumping tests and a pilot test using TAM injection were conducted, but both techniques didn\u2019t yield satisfying results. Consequently, the zones were treated using direct injection, with a combination of traditional\u00a0<strong>Direct Push (DP) technology<\/strong>\u00a0and, for the less permeable zones, our\u00a0<strong>SPIN\u00ae Injection Technology<\/strong>. In a zone, after two DP phases, it was decided to also inject a specific sub-zone using the SPIN\u00ae Injection Technology, as DP injections showed poor efficiency due to pollutant concentration rebound and heterogeneous distribution of injected reagents, as evidenced by electrical conductivity (EC) analyses performed by the remediation company (see below).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-05143f6 e-con-full e-flex e-con e-child\" data-id=\"05143f6\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-5ae986e elementor-widget elementor-widget-image\" data-id=\"5ae986e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"800\" height=\"602\" src=\"https:\/\/injectis.com\/wp-content\/uploads\/2025\/04\/ISCO-treatment-of-chlorinated-ethenes-in-clay-soil-monitored-by-electrical-tomography-Bretagne-France-1024x771.jpg\" class=\"attachment-large size-large wp-image-2042\" alt=\"\" srcset=\"https:\/\/injectis.com\/wp-content\/uploads\/2025\/04\/ISCO-treatment-of-chlorinated-ethenes-in-clay-soil-monitored-by-electrical-tomography-Bretagne-France-1024x771.jpg 1024w, https:\/\/injectis.com\/wp-content\/uploads\/2025\/04\/ISCO-treatment-of-chlorinated-ethenes-in-clay-soil-monitored-by-electrical-tomography-Bretagne-France-300x226.jpg 300w, https:\/\/injectis.com\/wp-content\/uploads\/2025\/04\/ISCO-treatment-of-chlorinated-ethenes-in-clay-soil-monitored-by-electrical-tomography-Bretagne-France-768x578.jpg 768w, https:\/\/injectis.com\/wp-content\/uploads\/2025\/04\/ISCO-treatment-of-chlorinated-ethenes-in-clay-soil-monitored-by-electrical-tomography-Bretagne-France.jpg 1386w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-9891f38 e-con-full e-flex elementor-invisible e-con e-parent\" data-id=\"9891f38\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;animation&quot;:&quot;fadeIn&quot;}\">\n\t\t<div class=\"elementor-element elementor-element-7714b1d e-con-full container__l e-flex e-con e-child\" data-id=\"7714b1d\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-b58514b e-con-full elementor-hidden-desktop elementor-hidden-laptop elementor-hidden-tablet_extra elementor-hidden-tablet elementor-hidden-mobile_extra elementor-hidden-mobile e-flex e-con e-child\" data-id=\"b58514b\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-8299d48 elementor-widget elementor-widget-image\" data-id=\"8299d48\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"800\" height=\"602\" src=\"https:\/\/injectis.com\/wp-content\/uploads\/2025\/04\/Afbeelding1-1024x771.jpg\" class=\"attachment-large size-large wp-image-2149\" alt=\"Laboratory optimisation\" srcset=\"https:\/\/injectis.com\/wp-content\/uploads\/2025\/04\/Afbeelding1-1024x771.jpg 1024w, https:\/\/injectis.com\/wp-content\/uploads\/2025\/04\/Afbeelding1-300x226.jpg 300w, https:\/\/injectis.com\/wp-content\/uploads\/2025\/04\/Afbeelding1-768x578.jpg 768w, https:\/\/injectis.com\/wp-content\/uploads\/2025\/04\/Afbeelding1.jpg 1386w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-33bab60 e-con-full e-flex e-con e-child\" data-id=\"33bab60\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-d56314c elementor-widget elementor-widget-heading\" data-id=\"d56314c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Reaction and reagents<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ce62565 elementor-widget elementor-widget-text-editor\" data-id=\"ce62565\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Based on the results of preliminary laboratory and on-site pilot tests, the remediation contractor selected sodium persulfate as the most suitable oxidant for the in situ chemical oxidation (ISCO) of the chlorinated ethenes.

For the low-permeability and heterogeneous zones, the remediation contractor selected the&nbsp;<strong>SPIN\u00ae Injection Technology<\/strong>&nbsp;as the most suitable injection technique.<\/p>\n<p>The selection of the most suitable injection technologies was based on a preliminary study by the remediation company. For this purpose, they developed a method to monitor injection distribution using&nbsp;<strong>electrical tomography<\/strong>, placing electrodes inside monitoring wells located around and within the injection zone. These electrodes allowed for the detection of changes in&nbsp;<strong>electrical resistivity<\/strong>&nbsp;before and after injection.<\/p>\n<p>Since&nbsp;<strong>sodium persulfate<\/strong>&nbsp;is an ionic salt, its presence in the groundwater alters the soil\u2019s electrical resistance. This enables, through interpolation and graphical representation (including&nbsp;<strong>3D visualization<\/strong>), the assessment of the injection\u2019s impact, radius of influence and reagent distribution and allowed adjustment of the injection grid after each injection phase. This ensures the most&nbsp;<strong>homogeneous treatment<\/strong>&nbsp;of the area and maximizes the efficient usage of the injected reagents by optimizing the direct contact between the oxidant and the contaminants.
