Groundworks case studies

Contaminated sites case studies:

Former Ilford site, Marly, historical and technical preliminary assessment in accordance with the Contaminated Sites Ordinance (CSO)

From 1980 until 2013, Marly was home to a cutting-edge factory producing film and photographic paper. Owing to the site's industrial past, it was deemed to require further investigation and was entered in the Register of Contaminated Sites. Ecosens carried out a historical survey of the site.

Subsoil remediation using excavated soil (stopping contamination at source), Lupfig/Hausen (AG)

As a result of previous production processes, there was soil and groundwater contamination on the former Reichhold Chemie site in Hausen and Lupfig. To enable the site to be developed and built on in the future, cutting-edge technology was used to ensure that pollutants present in the ground could be reduced to a minimum. Under the planning and management of Ecosens AG, excavation work incorporating the site's groundwater was undertaken.

Shooting range case studies:

Decontamination project and site remediation for 50 m and 300 m shooting ranges at Sohr, Windisch

The municipality of Windisch needed to remediate the 50 and 300 m bullet trap at the decommissioned Sohr shooting range in line with statutory site decontamination requirements. Due to its position in the agricultural zone, the remediation work entailed breaking up all concrete structures and recultivating high-grade agricultural land. Ecosens AG provided support to the municipality of Windisch at all stages of the project, from planning to implementation.

300 m shooting range at Oberlaupen, Wald, project development, submission and site remediation

Remediation of bullet trap, in line with statutory site decontamination requirements, at the decommissioned Oberlaupen shooting range, which is situated on a steep hillside in a forested area of agricultural land. The exposed position of the bullet trap represented a huge challenge in terms of logistics and accessing the site. The work to remediate the site included removing and disposing of almost 1,000 tons of heavily contaminated material from the bullet trap. Following the clean up, the area was recultivated in line with the surrounding habitat and trees were replanted.
