Since two weeks ago, the contractor Veolia is installing the remediation equipment at site Färgaren, Kristianstad. More than one hundred thermal elements are to be installed to a depth of approximately 20 m. Before each thermal element is installed a casing of metal pipe is carefully drilled while the contaminated soil and water returning to the surface is collected and taken care of, to make sure the contaminant is not spread. The thermal element is then installed inside the metal casing and the space around it is filled with controlled material. After that the metal casing is removed.
When all the thermal elements are in the ground, a pipe system close to the ground surface supposed to collect the evaporated gas, including the PCE contaminant, will be installed. The pipe system will transport the gas into a container including tanks filled with activated carbon, which will clean the gas from the PCE and return clean water to the recipient. The pipe system will be installed during May and June.
During the whole installation and the remediation process, supposed to start in August, careful control of soil samples, process water and air quality, is carried out by Hanna Lindvall at Tyréns and member of the MIRACHL team. In certain groundwater observation wells, pressure gauges also continuously measure the groundwater, also taken care of by Hanna.
Swedish television, SVT, was taking notice of the Färgaren remediation project during the first week of the installation. In addition, the local news Kristianstadsbladet also visited the site, resulting in the article Nu ångar saneringsarbetet igång på allvar – Kristianstadsbladet.
