Reliable Partner for Environmental Projects
Responsible management of the environment and natural resources is a key part of Bosch Group’s sustainability strategy. For over a decade, CDM Smith has supported Bosch as a general contractor for environmental assessments and contaminated site remediation at multiple locations in Japan.
Smooth Transition to Reuse
The remediation laid the foundation for the successful sale of a former Bosch site and its redevelopment into a new shopping center.
Project Context and Scope
After CDM Smith had already been entrusted with extensive site investigations for several contaminants of concern at the former Robert Bosch Japan Higashimatsuyama 2 site from 2012 to 2017, Robert Bosch GmbH commissioned CDM Smith in 2018 to carry out soil and groundwater remediation of site areas impacted with chlorinated hydrocarbons and hexavalent chromium.
Remediation Measures
Remedial tasks at the Higashimatsuyama 2 site included soil excavation of hexavalent chromium impacted soil via over drillings using large diameter (2-metre) augers, dechlorination of VOC impacted areas via groundwater injection of biostimulants, installation of upgradient zero-valent iron reactive barriers, and in-situ reduction of hexavalent chromium to non-toxic trivalent chromium in some site perimeter areas via injection of a mixture of ferrous sulphate and molasses. This process, fairly common at CDM Smith remediation sites in the USA, is unusual in Japan and presented the best approach to the technical challenges associated with overhead powerlines, nearby housing, and an adjacent public street. A planned second in-situ treatment was not necessary, as CDM Smith supported Bosch in the Purchase and Sale Agreement negotiations for the property and thus reached an agreement with the buyer to assume the residual risk of the immobilized areas.
For three chlorinated hydrocarbon source areas, CDM Smith conducted limited soil excavation in near surface areas and in-situ anaerobic degradation for the remaining source areas.
Project Results and Added Value
The former Bosch site Higashimatsuyama 2 site was sold in April 2018 and until 2020 a Shopping mall was constructed and completed by the new owner. The 2-year groundwater monitoring programme, as requested by Japanese regulatory authorities, was executed in parallel to the construction activities and finalized in March 2021 with no exceedance of any official remediation threshold. In June 2021, the Japanese regulatory authorities removed the site from the official contaminated land cadaster. With the successful completion of the remediation prior to selling the property, CDM Smith generated value added for Bosch, since the selling price exceeded the remediation costs by far.
Following the successful remediation at the Higashimatsuyama Bosch site in 2021, CDM Smith, under the direction of Mr Franzel, has continued to advise Bosch on site investigations at various Bosch properties in Japan, including the new Bosch Headquarters building site in Yokohama and several production sites in the Tokyo area.
