Waste Water Sampling and On spot Analysis

On-spot parameters for the analysis of wastewater refer to the parameters that can be quickly measured or assessed directly at the sampling site, without the need for laboratory analysis. These parameters provide immediate insights into the quality of the wastewater and can help guide decision-making processes. Here are some common on-spot parameters for wastewater analysis.


pH measures the acidity or alkalinity of the wastewater. It is an important parameter as it can influence the behavior of pollutants and the effectiveness of treatment processes.


Wastewater temperature can affect various biological and chemical processes, such as microbial activity and the solubility of contaminants.


Turbidity is a measure of the cloudiness or haziness of the wastewater caused by suspended particles. High turbidity levels can indicate the presence of solids or other particulate matter.


Conductivity measures the ability of the wastewater to conduct electricity and is related to the concentration of dissolved ions, such as salts and metals. It can provide insights into the overall salinity and ion composition of the wastewater.

Dissolved Oxygen (DO)

DO levels indicate the amount of oxygen dissolved in the wastewater? Low DO levels can indicate poor water quality and inadequate oxygenation, which may be harmful to aquatic organisms.

Total Suspended Solids (TSS)

TSS represents the total concentration of suspended solids in the wastewater. High TSS levels can indicate poor water quality and may affect clarity, oxygen levels, and aquatic habitat.

Chemical Oxygen Demand (COD)

COD measures the amount of oxygen required to chemically oxidize organic and inorganic compounds in the wastewater. It provides an indication of the organic load and the potential for oxygen depletion in receiving water bodies.

Biochemical Oxygen Demand (BOD)

BOD measures the amount of oxygen consumed by microorganisms during the biochemical degradation of organic matter in the wastewater. It provides insights into the biodegradability of organic pollutants and the potential for oxygen depletion in aquatic environments.


Ammonia is a nitrogen compound commonly found in wastewater. High levels of ammonia can indicate the presence of organic matter or inadequate treatment of nitrogen-containing compounds.


Phosphorus is another nutrient often found in wastewater. Elevated phosphorus levels can contribute to eutrophication and algal blooms in receiving water bodies.

These on-spot parameters provide valuable information about the immediate quality of wastewater and can help in making rapid assessments and decisions regarding treatment processes, discharge management, and environmental protection measures.
