Water Testing & Environmental Microbiology

Orion Microbiology provides reliable, ISO-aligned water testing and environmental microbiology services designed to support compliance, risk management and informed decision-making. We work with commercial, public sector and research clients to deliver clear, defensible microbiological data you can trust.

ISO-Aligned Water Microbiology Testing

All water and environmental microbiology testing is carried out in line with relevant ISO standards, ensuring consistency, accuracy and confidence in results. This includes alignment with standards such as:

 

  • ISO 19458 – microbiological water sampling and handling
  • ISO 11133 – preparation and performance of microbiological culture media
  • Applicable ISO methods for indicator organisms, pathogens and general water quality assessment

 

Our laboratory operates within a quality framework aligned with ISO/IEC 17025 principles, giving assurance that results are suitable for regulatory, quality and internal reporting purposes.

Comprehensive Water Testing Services

We provide microbiological testing for a wide range of water types, including potable, process and environmental waters. Our routine and specialist analyses include:

 

  • Total viable counts and general hygiene indicators
  • Coliforms and E. coli
  • Pseudomonas species
  • Legionella monitoring for building and water systems

 

Testing strategies are selected to match your regulatory obligations and operational requirements.

Environmental Microbiology Services

Our environmental microbiology services go beyond routine compliance testing. We support monitoring programmes and investigations that require a deeper understanding of microbial presence and behaviour in environmental systems, supported by clear interpretation and practical insight.

Bespoke & Project-Specific Analysis

Where standard testing is not sufficient, we offer bespoke microbiological analysis tailored to your application. We work closely with clients to design customised testing programmes, including non-routine organisms, specialist sampling approaches and project-specific methodologies.

 

For tailored studies or ongoing support, our Bespoke & Contract Research services provide flexible, collaborative solutions.
