Water and Sludge Sampling (Grab/Composite)

Why Professional Water Sampling is Critical for Reliable Results?

The accuracy of water quality analysis begins with professional sampling and continues with proper sample transport to the laboratory. Professional sampling ensures:

1. Full representativeness of the sample – accurately reflecting the characteristics of the water source.
2. Prevention of cross-contamination – maintaining sample purity throughout the process.
3. Preservation of sampling conditions – maintaining proper temperature and storage conditions.
4. Complete and accurate documentation – ensuring detailed records for reliable and precise analysis.

Frequently Asked Questions

• Why is professional water sampling important?
  • To ensure that the water sample accurately represents the characteristics of the water source, prevent cross-contamination, maintain proper sampling conditions, and provide reliable results for laboratory analysis.
• What is the difference between grab sampling and composite sampling?
  • Grab sampling is a single, discrete sample collected at a specific point in time.
    Composite sampling is performed over a defined period and combines multiple subsamples to create an average representation of conditions.
• Which types of water and sludge can be sampled?
  • Industrial wastewater, sanitary wastewater, sludge and liquid waste, reclaimed water, stream water, and recreational water, depending on the purpose of the sampling and applicable regulations.
• Which field tests are performed during sampling?
  • Measurement of immediate parameters such as pH, turbidity, chlorine, dissolved oxygen, and temperature, as part of the assessment of environmental conditions at the time of sampling.
• Who is authorized to perform water and sludge sampling?
  • Experienced and certified samplers operating in accordance with Ministry of Health and Ministry of Environmental Protection procedures and under ISO 17025 accreditation.
• What does the final report provided to the client include?
  • Professional analysis of the test results, assessment of the condition of the water or sludge source, and evidence-based recommendations for improvement, treatment, or continued monitoring as required.
