Initial Situation – area and contamination: The industrial area in R\u00f6dermark, Hessen with a size of 14,8 acres has been used by different industrial companies for the last 100 years, including for the production of electronic goods. As a result there is substantial contamination by organic solvents (CHC). Today the site houses a well-known hardware store and other commercial units.<\/p>\n
History of rehabilitation<\/strong><\/p>\n In the period from 1998 to 2009 remedial actions with soil vapor extraction and groundwater extraction took place. The actions did not achieve any considerable decontamination. From 2010 to 2012 tests for the feasibility of microbiological rehabilitation were performed but also with no success.<\/p>\n Decontamination with ISCORAPID<\/strong><\/p>\n Prior to the start of the remediation with ISCORAPID in 2014 the concentration of CHC in groundwater was 185.000 \u03bcg\/l. The primary contaminant was trichloroethylene.<\/p>\n Within one year GEO-BOHRTECHNIK injected the oxidizer potassium permanganate during four injection events into the underground. After the fourth injection, in the beginning of 2015, the contamination was reduced to 6.579 \u03bcg\/l CHC. By 2016 residual contamination at the monitoring points was 3,8 \u03bcg\/l CHC.<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″][et_pb_gallery admin_label=”Galerie” fullwidth=”on” show_title_and_caption=”on” show_pagination=”off” background_layout=”light” auto=”on” hover_overlay_color=”rgba(255,255,255,0.9)” caption_all_caps=”off” use_border_color=”on” border_color=”#e8e8e8″ border_style=”solid” gallery_ids=”227,228,230,229,231″ \/][et_pb_divider admin_label=”Teiler” color=”#ffffff” show_divider=”off” height=”50″ divider_style=”solid” divider_position=”top” hide_on_mobile=”on” \/][et_pb_text admin_label=”Text” background_layout=”light” text_orientation=”left” use_border_color=”off” border_color=”#ffffff” border_style=”solid” disabled_on=”on|on|on” disabled=”on”]<\/p>\n Projekt:<\/p>\n Auftraggeber:<\/p>\n Aufgabe:<\/p>\n Jahr:<\/p>\n Dauer:<\/p>\n Status:<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row admin_label=”Zeile” disabled_on=”on|on|on” disabled=”on”][et_pb_column type=”4_4″][et_pb_image admin_label=”Bild” src=”https:\/\/www.iscorapid.de\/wp-content\/uploads\/2017\/01\/p_01_chart.svg” show_in_lightbox=”off” url_new_window=”off” use_overlay=”off” animation=”fade_in” sticky=”off” align=”left” force_fullwidth=”off” always_center_on_mobile=”on” use_border_color=”off” border_color=”#ffffff” border_style=”solid” \/][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":" Success story – R\u00f6dermark Initial Situation – area and contamination: The industrial area in R\u00f6dermark, Hessen with a size of 14,8 acres has been used by different industrial companies for the last 100 years, including for the production of electronic goods.
