Microbiological water testing evaluates water samples for microorganisms that may affect public health, regulatory compliance, water quality, and operational performance.

PBR Laboratories provides microbiological testing for drinking water, potable water systems, groundwater, surface water, recreational water, industrial water, and environmental monitoring programs throughout Alberta, Western Canada, and Canada.

Results help organizations determine whether water systems are functioning effectively and whether corrective actions may be required.

What Is Microbiological Water Testing?

Microbiological water testing evaluates water samples for bacteria and other microorganisms that may indicate contamination, treatment failures, distribution system issues, or public health risks.

Testing may be used to:

  • Verify drinking water safety
  • Monitor treatment effectiveness
  • Investigate contamination events
  • Support regulatory compliance
  • Evaluate environmental water quality
  • Monitor recreational water

Who Needs Microbiological Water Testing?

Municipalities Drinking water systems and distribution networks.
Environmental Consultants Groundwater and surface water investigations.
Industrial Facilities Process water and operational water systems.
Food & Beverage Manufacturers Ingredient water and potable water programs.
Commercial Facilities Building water systems and water quality monitoring.
Recreational Facilities Beach and recreational water monitoring.
