Water testing refers to the analysis of water quality parameters in various types of water—drinking water, surface water, groundwater, wastewater, industrial effluent, and more. These tests evaluate the presence of chemical, physical, and biological contaminants, ensuring compliance with health, environmental, and industrial standards.
Water testing refers to the analysis of water quality parameters in various types of water—drinking water, surface water, groundwater, wastewater, industrial effluent, and more. These tests evaluate the presence of chemical, physical, and biological contaminants, ensuring compliance with health, environmental, and industrial standards. Water testing plays a crucial role in public health protection, environmental monitoring, process control in industries, and regulatory reporting. It helps detect both routine indicators (e.g., pH, turbidity) and trace contaminants (e.g., heavy metals, PFAS, VOCs, bacteria).
Typical turnaround is 3–7 business days. Rush services available upon request.
Yes. Our testing reports follow ISO/EPA norms and can be used for permit and audit submissions.
Yes, on-site sampling can be arranged depending on location and project scope.
COD measures chemically oxidizable organic matter; TOC measures total organic carbon. They reflect different aspects of organic pollution.
Yes, we offer high-sensitivity LC-MS/MS analysis for ultra-trace organics (ppt level).
Typical Water Types and Applications
| Water Type | Common Applications |
|---|---|
| Drinking water | Compliance with health standards, consumer safety |
| Surface water (lakes, rivers) | Environmental monitoring, ecological risk assessment |
| Groundwater | Contamination tracking, agricultural suitability |
| Industrial wastewater | Effluent treatment verification, discharge permit compliance |
| Cooling/process water | Corrosion control, scale/deposit monitoring |
| Seawater | Desalination pre-screening, marine monitoring |
