EnISSA

What EnISSA does

EnISSA is a Belgian-based specialised environmental services firm, operated as a trade name of Witteveen+Bos Belgium N.V., that provides High Resolution Site Characterisation (HRSC) investigations for soil and groundwater contamination. Founded within Witteveen+Bos around 2009 and commercially deployed from 2010, the company serves environmental consultants, brownfield developers, regulators, and industrial problem owners across eight European countries (Belgium, Netherlands, France, Germany, Denmark, Switzerland, Hungary, and Spain).

The company's core offering combines direct-push sensor technologies with laboratory-quality field analysis. Its proprietary toolset includes the MIP with GC-MS Detection system (identifying individual VOCs every 30 cm along probe depth), the Optical Image Profiler using UV fluorescence for PAH and fuel/oil mapping, the Hydraulic Profiling Tool for continuous permeability profiling, Electric Conductivity dipole measurements, the GroundWater Profiler for multi-depth sampling, and on-site GC-MS analysis for soil gas and indoor air. Results stream in real time to a proprietary Data Dashboard accessible both on-site and remotely, and feed into 3D visualisation models that integrate HPT, EC, groundwater interval results, and concentration volume estimates. EnISSA operates with two direct-push rigs, two field labs, and five operational field teams coordinated from Vilvoorde, Belgium.

EnISSA generates revenue through professional services — project-based HRSC investigations and drilling/sampling campaigns — priced on a quote basis tailored to project scope. The go-to-market is enterprise field sales with direct engagement, multi-language website presence (NL/EN/DE/FR), case studies, and demo request CTAs targeting consultants and problem owners. Named enterprise and mid-market customers include Arcadis Netherlands, Robert Bosch, A+E Consult, and Wescon Miljökonsult AB. The company has no external venture funding and operates as a specialised business unit within Witteveen+Bos Belgium N.V., which provides institutional backing and access to broader consulting relationships.

Others

• Geoprobe Systems: US manufacturer of direct-push drilling rigs and tooling (the equipment platform EnISSA uses for MIP, HPT, and GWP investigations). EnISSA's service model relies on Geoprobe equipment, making them an enabling infrastructure peer rather than a direct competitor.
• Solinst Canada: Manufacturer of groundwater monitoring instruments, sampling equipment, and water level data loggers used in site assessment and contamination studies—an enabling technology peer to EnISSA's groundwater and drilling operations.

Direct peers

• Cascade Environmental Group: US-based direct-push services firm offering MIP, HPT, and other HRSC logging services for environmental site characterization. Closest comparable service provider in business model and toolset, though operating in North America rather than Europe.

Broad incumbents

• Arcadis: Global design and consultancy firm and an EnISSA customer; also delivers brownfield site assessment and remediation advisory at scale, making it both a buyer and a broad competitive overlap in the same end markets.
• AECOM Environment: Global infrastructure consulting firm with substantial environmental services practice including site assessment, PFAS investigation, and remediation advisory that overlaps EnISSA's enterprise and developer segments at much larger scale.
• Haley & Aldrich: US environmental and geotechnical engineering firm with deep HRSC and high-resolution site characterization practices serving industrial, real-estate, and public-sector clients comparable to EnISSA's segments.
• SLR Consulting: Global environmental and advisory consultancy with site investigation, contamination assessment, and remediation services aimed at industrial, developer, and infrastructure clients across Europe.
• Wood Environment & Infrastructure (Wood plc): Large global environmental services and consulting firm with site investigation and remediation capabilities that overlap with EnISSA's delineation work, typically as part of much broader portfolios.
• Witteveen+Bos: Dutch engineering and environmental consultancy and EnISSA's parent group. Operates broadly in water, environment, and infrastructure, overlapping with EnISSA's HRSC services through larger, multi-disciplinary project work.

Regional players

• TAUW Group: European environmental and engineering consultancy headquartered in the Netherlands with site investigation, soil/groundwater, and remediation services directly comparable to EnISSA's end markets, though without EnISSA's specialization in MIP-based HRSC.
