What Aqualysis does

Aqualysis Waterlaboratorium is an accredited water analysis laboratory headquartered in Zwolle, Netherlands, established in 2014 as a Gemeenschappelijke Regeling (shared service organization) jointly owned by five Dutch water boards: Waterschap Vallei en Veluwe, Waterschap Rijn en IJssel, Waterschap Drents Overijsselse Delta, Waterschap Zuiderzeeland, and Waterschap Vechtstromen. The laboratory operates under RvA L230 accreditation (NEN-EN-ISO/IEC 17025) and ministerial recognition AS2000 and AS3000, providing legally defensible data for regulatory reporting under the EU Water Framework Directive (KRW) and Dutch Water Act.

The company delivers a multi-disciplinary service portfolio spanning chemical analysis (organic, inorganic, metals), hydrobiological research (macrofauna, phytoplankton, diatoms, vegetation, fish, amphibians), bacteriological swimming water testing, waterbed/sediment research, and environmental DNA (eDNA) analysis. Core analytical platforms include High-Resolution Mass Spectrometry (HRMS) for non-target screening, LC-MS for PFAS detection at 0.05–0.5 ng/l across 50+ compounds, GC-MS for pesticides and volatiles, ICP-MS for metals, qPCR for species-specific DNA, and Solid Phase Extraction for sample preconcentration. The company maintains an in-house macrofauna reference collection being DNA-barcoded through the ARISE program. Its specialized "Brede Screening" offering integrates sensors, HRMS, and eDNA into a three-layer monitoring architecture.

Commercially, Aqualysis operates on a quotation-based, pay-as-you-go professional services model with revenue derived from commissioned monitoring and research contracts. Five co-owning water boards are the dominant customer base, supplemented by municipalities, provinces, Rijkswaterstaat, and private engineering bureaus. The organization runs 24/7 emergency sampling and processes over 40,000 samples annually, including routine monitoring networks, KRW compliance testing, Quickscan Stedelijk Water (60 urban water bodies for Waterschap Rijn en IJssel), and swimming water quality control at ~100 locations. Pricing is not publicly disclosed; service specifications are published via the Producten en Diensten Catalogus.

Core offering

Aqualysis is an accredited water laboratory (RvA L230) that provides comprehensive water quality research services, including sampling, chemical analysis, bacteriological testing, hydrobiological research, and eDNA-based species detection, primarily for Dutch water boards and other public-sector clients. The laboratory is equipped with modern analytical techniques such as High-Resolution Mass Spectrometry (HRMS), LCMS, GC-MS, ICP-MS, and qPCR to detect contaminants, monitor biodiversity, and support regulatory compliance.

Product overview

Aqualysis is an accredited water laboratory (RvA L230) offering comprehensive water quality research services. The portfolio consists of core sampling and analysis services (Monsterneming, Chemisch Onderzoek, Hydrobiologisch Onderzoek, eDNA Analysis) and specialized sub-products (PFAS Monitoring, Bacteriological Swimming Water Research, Waterbed Research, Toxicity Testing, Quickscan Stedelijk Water). The eDNA analysis service enables species detection without catching organisms, while the chemical analysis covers organic chemistry, metals, and inorganic parameters.

Scale indicators7 records

Recent moves7 records

Expansion highlights5 records

Broad incumbents

• ALS Global (Environmental): ALS is a global analytical services network with a strong European water-testing practice, including PFAS and metals panels; it overlaps with Aqualysis's chemistry and emerging-contaminant capabilities while serving international industrial and municipal clients.
• SGS Water & Environment Netherlands: SGS is a global testing, inspection, and certification incumbent with a Dutch environmental laboratory footprint covering water, wastewater, and emerging contaminant analyses; comparable in offering breadth but operating across multiple industries and geographies.
• Bureau Veritas Laboratories (Netherlands): Bureau Veritas operates environmental and water-testing laboratories in the Netherlands supporting industrial compliance, PFAS monitoring, and wastewater characterization; a broad incumbent serving similar regulated customers with a wider service portfolio.
• Eurofins Environment Testing Netherlands: Eurofins is a global environmental testing incumbent operating a broad portfolio of accredited water, soil, and air analyses in the Netherlands, including PFAS and pesticide panels; it competes with Aqualysis for private-sector and municipal water-testing contracts while serving a much wider geography.

Others

• Deltares: Deltares is a Dutch applied research institute in water, subsurface, and infrastructure that co-developed pesticide extraction methodologies used by Aqualysis; it operates as a knowledge partner in national water-quality research rather than a direct competitor for routine lab services.
• TNO (Netherlands Organisation for Applied Scientific Research): TNO is a Dutch applied research organization that co-developed the large-volume pesticide extraction method later refined by ILOW labs (including Aqualysis); it is an R&D partner rather than a commercial competitor, but its methods underpin the analytical capabilities Aqualysis now operates at scale.
• Naturalis Biodiversity Center: Naturalis leads the ARISE DNA-metabarcoding program in which Aqualysis participates by contributing its macrofauna reference collection; Naturalis is a biodiversity research partner rather than a competitor, but the collaboration is central to Aqualysis's eDNA roadmap.

Regional players

• Wetterskip Fryslân Laboratory: The in-house laboratory of Wetterskip Fryslân is one of the six ILOW member labs serving the Frisian waterschap; it competes with Aqualysis for the same Dutch water-board analytical mandate and shares methodological standards via ILOW coordination.
• Waterschap Hunze en Aa's Laboratory: The laboratory affiliated with Waterschap Hunze en Aa's is another ILOW member lab serving a regional waterschap in the north of the Netherlands; it offers overlapping sampling, chemical, and biological analyses under the same national water-monitoring framework.

Direct peers

• AQUON: AQUON is another ILOW-affiliated Dutch water board laboratory serving waterschappen with chemical, biological, and eDNA analyses; it is the closest domestic peer and former employer of Aqualysis's current director, making it the most directly comparable competitor for shared water-board contracts.
