Why Microbiological Testing is Critical for Water & Wastewater

Bacteria, viruses, and other pathogens in water are a direct threat to public health and environmental safety. Whether it’s water for human consumption or wastewater being discharged, microbial contamination must be monitored and controlled.

At SWA Enviro, we offer accredited microbiological testing services to:

• Drinking water suppliers
• Mineral and packaged water bottlers
• STP/ETP/CETP operators
• Industries discharging wastewater
• Builders and developers seeking NOCs or EC

 

What We Test For

We identify the presence and concentration of key microbial indicators including:

• Total Coliforms
• Fecal Coliforms (E. coli)
• Fecal Streptococci / Enterococci
• Heterotrophic Plate Count (HPC)
• Pseudomonas aeruginosa
• Salmonella, Shigella, Vibrio species (for advanced requirements)
• Yeasts and Molds (in bottled water)

 

All analyses follow validated methods such as:

• Multiple Tube Fermentation (MPN)
• Membrane Filtration
• Spread Plate & Pour Plate Techniques

Legal & Regulatory Standards for Microbial Quality
