Nilsson Laboratorios is a Spanish company specializing in integrated water treatment and Legionella prevention, serving businesses, industrial facilities, hospitality operators, and public administrations across Spain. With more than 20 years of professional experience, the organization delivers end-to-end solutions that combine accredited laboratory analysis, field sampling, technical consulting, water treatment services, and specialized personnel training. Clients rely on Nilsson Laboratorios to achieve regulatory compliance, safeguard public health, and maintain the quality and safety of water in their installations. The laboratory's core analytical offering covers four principal water matrices. Drinking water analysis (análisis de agua de consumo) verifies potability through both microbiological testing — including total coliforms, Escherichia coli, Enterococcus, and heterotrophic plate counts — and physicochemical testing covering turbidity, pH, conductivity, nitrates, nitrites, hardness, chlorine residuals, and other parameters required under Spain's Royal Decree 140/2003 on quality criteria for water intended for human consumption. For wastewater (aguas residuales), the laboratory conducts studies to quantify critical discharge parameters that industrial and municipal clients must demonstrate before releasing effluent. Analytical scopes typically encompass biochemical oxygen demand (BOD), chemical oxygen demand (COD), suspended solids, nitrogen and phosphorus speciation, heavy metals, and relevant microbiological indicators, supporting compliance with Spanish and EU Water Framework Directive effluent limits. Continental water analysis — covering rivers, streams, aquifers, springs, and private wells (aguas superficiales y subterráneas) — characterizes both physicochemical and microbiological quality for environmental monitoring programs, water abstraction permitting, irrigation suitability assessment, and ecological status evaluation under the EU Water Framework Directive. The laboratory collects and processes field samples from diverse surface and groundwater environments throughout its operating territory. Legionella analysis is a flagship capability. Nilsson Laboratorios performs culture-based detection and quantification of Legionella pneumophila and other Legionella species in water samples drawn from high-risk installations including cooling towers (torres de refrigeración), steam boilers (calderas de vapor), hot and cold water distribution networks, decorative fountains, and other aerosol-generating systems. Sampling protocols, analytical methods, and reporting follow Spain's Technical Sanitary Regulation on Legionella Prevention (Real Decreto 865/2003), enabling facility owners and operators to meet their mandatory legal obligations for Legionella risk management and control. Nilsson Laboratorios holds ISO/IEC 17025 accreditation across its laboratories, the internationally recognized standard for testing and calibration laboratory competence. This accreditation confirms that the laboratory's sampling procedures, analytical methods, equipment calibration, uncertainty estimation, and quality management systems meet rigorous technical requirements set by a national accreditation body. ISO 17025 certification is particularly critical for clients whose test results must withstand regulatory inspection or legal scrutiny, and it underpins the reliability and traceability of every analytical certificate issued. The company operates two accredited laboratory facilities: one in Zaragoza, serving mainland Spain and particularly the Aragon region, and one in Lanzarote, providing direct coverage across the Canary Islands. This dual-site infrastructure minimizes sample transport times, preserves the integrity of time-sensitive microbiological specimens, and allows rapid field-sampling response. Both sites operate under the same quality management framework, ensuring consistent and comparable results regardless of which facility processes a given batch. Beyond analysis, Nilsson Laboratorios offers technical consulting and bespoke project design for water treatment systems — including reverse osmosis (ósmosis inversa), desalination, cooling tower chemical dosing, and pool water management — adapting each solution to the specific characteristics of the client installation. The company also delivers a structured training curriculum for maintenance personnel, with courses covering water operator qualification (manipulador de aguas), steam boiler operation, Legionella risk management for hazardous installations, osmosis and desalination operation, pool maintenance, and correct sample collection technique. Courses are offered under Spain's subsidized training scheme (100% subvencionables), making professional qualification accessible to clients across hospitality, healthcare, industry, agriculture, and municipal services sectors.
