  • Faecal Coliforms and Escherichia coli (SMEWW 9222D), and
  • Enterococcus (SMEWW 9230 C).

Recreational Water Quality Certification:

Our certificates are issued to swimming pool and water park operators desirous of demonstrating to patrons their ability to maintain continuously compliance with strict water quality guidelines. The certificate covers are range of microbiological and physiochemical parameters in accordance with international best practices, and is done on a periodic basis.



Blue Flag Monitoring Programme:

We support such initiatives locally and regionally by offering a range of services which align to the Blue Flag criteria:


Beach water quality parameters:

Escherichia Coli, Intestinal Enterococci, pH, Temperature, Turbidity, Visible Mineral Oil on Surface, Tarry Residues/ Floating Matter


Coastal Sewage Treatment Plant (STP) effluent:

Faecal Coliforms and Biochemical Oxygen Demand


  • Agricultural/Irrigation Water

We can collect and test water destined for field irrigation or aquaponics (hydroponics and aquaculture) for the most common water quality microbiological indicators such as Total Coliforms, Faecal Coliforms and Escherichia Coli.

  • Ballast Water Monitoring

  • Virtually any sample matrix can be analyzed
    • g. raw materials, food products, potable water, recreational water (marine and freshwater), beverage, soil, sludge, surfaces, air, chemicals, wastewater/effluent, dust, etc. 
  • Powerful Tool used for
    • Proactive screening
    • Characterizing unknown biological matter
    • Tracing sources of contamination throughout critical areas of a process line
    • In depth investigation of high total bacterial and fungal counts
    • Detection of objectionable microbes

Going beyond the limitations of traditional microbial indicators
