Lambda Consult was founded in the early 1980s by Reinout Lageman, as a consulting firm in the field of international assessment studies for groundwater exploration and exploitation. In the mid 1980s the company became also involved in environmental issues and the development and application of novel in-situ ground and groundwater remediation technologies like Electro-Reclamation (also called Electro-Remediation), Electro-Bioremediation and subsurface containment and remediation barriers like Electrokinetic Fences and Electrokinetic Biofences.

In 1987 Lambda Consult was one of the founding companies of Geokinetics BV, the first company in the world which developed and commercialized the technology of Electro-Reclamation and its derivative remediation technologies. As managing partner in Geokinetics BV and later on as technical advisory partner of the Holland Environment Group, Lambda Consult has been and still is involved in groundwater assessment studies and groundwater modeling, numerous in-situ ground and groundwater remediation projects, polluted site assessments, feasibility studies, remediation plans, and environmental investigations all over the world. In the United States we have given technical backup to Geokinetics International Inc. from 1995 till 2002. In Japan we have given technical support and training from 2002 till 2005 in the field of in-situ Electro-Remediation as consultant of Holland Environment BV to the companies Shimadzu, Asanuma, Fuji Environ and Mirai. Since the beginning of 2008 we support and train Showa Denko Corporation in Japan in the same field. In that year we have also been involved in a pilot project in Italy for the in-situ removal of elemental mercury from soil and groundwater in cooperation with Saipem S.p.A.
