Culture, viability PCR (vPCR), and quantitative PCR (qPCR).

Legionella testing is an important component of building water management programs, particularly in facilities with complex plumbing systems, cooling towers, and other aerosol-generating water systems.

Our Legionella testing services support building water management programs, including routine monitoring, investigations and treatment effectiveness evaluations. Culture, viability PCR (vPCR) and quantitative PCR (qPCR) provide complementary analytical options to address the specific objectives and needs of each water management program.

Evaluate microorganisms associated with corrosion, biofilm formation and biofouling. 

Microbial activity can contribute to biofilm development, reduced system efficiency, and microbiologically influenced corrosion (MIC) in industrial water systems, cooling towers, closed-loop HVAC systems, and data center cooling infrastructure.

Our comprehensive MIC testing panel includes the detection and/or quantification of the following microbial groups:

• Iron-Related Bacteria (IRB)
• Sulfate-Reducing Bacteria (SRB)
• Acid-Producing Bacteria (APB)
• Slime-Forming Bacteria
• Denitrifying Bacteria
• Pseudomonas aeruginosa quantification

These analyses help characterize microbial populations associated with corrosion and biofilm-related problems. Results can provide valuable data to support system investigations, treatment optimization, biocide selection, and ongoing water system monitoring.

Microbial indicators for drinking water systems.

Maintaining appropriate microbial water quality is an important part of potable water management in commercial, institutional, industrial, and healthcare facilities.

Our potable water testing services help clients evaluate microbial conditions and support routine water quality monitoring.

Testing includes:

• Heterotrophic plate count (HPC): Measures culturable heterotrophic bacteria and supports evaluation of general microbial water quality.
• Total coliform: Detects indicator organisms used to assess drinking water quality and potential contamination.
• E. coli: Identifies an important indicator of fecal contamination.

These tests support routine monitoring, investigation of water quality concerns, and evaluation of water distribution systems.

Supporting water quality monitoring for medical device processing.

Water quality is critical to the effective cleaning, rinsing, disinfection, and sterilization of reusable medical devices. Our testing services provide data to support water quality evaluation and monitoring under ANSI/AAMI ST108 – Water for the Processing of Medical Devices.

Available testing includes:

• Water chemistry, including applicable metals, anions, hardness, alkalinity, conductivity, and other parameters
• Heterotrophic Plate Count (HPC)
• Bacterial Endotoxin Testing

Testing programs can be tailored to Utility Water, Critical Water, and steam condensate applications, including baseline qualification and routine monitoring.
