Testing scope
Choose Chem-Tech for Reliable Wastewater Testing Services
Chem-Tech provides wastewater testing for defined process, discharge or monitoring requirements. Confirm the sampling plan, applicable limits, analytical methods and reporting scope before collection.
Technical review
Common water-quality and contamination concerns
pH and mineral balance
pH, alkalinity, hardness and dissolved-ion results are reviewed together with the water source and intended use.
Dissolved and suspended material
Dissolved solids, suspended solids and turbidity support review of clarity, treatment and process-related concerns.
Microbiological condition
Microbiological parameters are selected for the water use, sampling point and applicable requirement.
Requirement and sampling context
Interpretation depends on the identified standard, representative sampling, preservation and the time between collection and testing.
Published laboratory capability
Tests and test methods
The methods below are matched to Chem-Tech's controlled technical test lists and published laboratory capability. The final scope is confirmed for the sample, specification and current laboratory capability.
| Test / parameter | Published test method | Technical purpose | Interpretation / high-low context |
|---|---|---|---|
| Elemental Analysis | ASTM D1976 / CTP-T-125 | Reports selected wear, contaminant, additive or composition-related elements. | Higher or lower values require comparison with formulation, metallurgy, process inputs and trend history; one result alone does not establish the source. |
| Ammonia / Ammoniacal Nitrogen | APHA 4500-NH3-C / IS 3025 Part 34 | Quantifies the selected dissolved ion or nutrient-related parameter. | A higher or lower result is assessed against the identified water-use requirement and may indicate source, treatment, contamination or process effects. |
| Nitrate | APHA 4500-NO3-B / IS 3025 Part 34 | Quantifies the selected dissolved ion or nutrient-related parameter. | A higher or lower result is assessed against the identified water-use requirement and may indicate source, treatment, contamination or process effects. |
| Chloride | APHA 4500-Cl-B,D / IS 3025 Part 32 | Quantifies the selected dissolved ion or nutrient-related parameter. | A higher or lower result is assessed against the identified water-use requirement and may indicate source, treatment, contamination or process effects. |
| Conductivity | APHA 2510-B / IS 3025 Part 14 | Assesses ionic or dissolved-material content in water. | A higher result generally indicates more dissolved ionic material; significance depends on the water source, treatment and intended use. |
| Dissolved Oxygen | APHA 4500-O-B,C / IS 3025 Part 38 | Measures oxygen dissolved in the water sample. | Lower values may indicate oxygen demand or limited aeration; higher values reflect greater oxygen availability under the sampling conditions. |
| Oil and Grease | APHA 5520-B:2017 / IS 3025 Part 39 | Assesses organic, oxidisable or hydrocarbon-related loading in water. | A higher result indicates greater loading under the selected method and may affect treatment, discharge or process suitability. |
| pH | APHA 4500-H+-B / IS 3025 Part 11 | Measures acidity or alkalinity of the sample under the selected procedure. | A result above or below the required range may affect treatment control, corrosion, scaling, process suitability or product conformity. |
| Sulphate | APHA 4500-SO4-E / IS 3025 Part 24 | Quantifies the selected dissolved ion or nutrient-related parameter. | A higher or lower result is assessed against the identified water-use requirement and may indicate source, treatment, contamination or process effects. |
| Total Dissolved Solids | APHA 2540-C / IS 3025 Part 16 | Assesses ionic or dissolved-material content in water. | A higher result generally indicates more dissolved ionic material; significance depends on the water source, treatment and intended use. |
| Total Suspended Solids | APHA 2540-D / IS 3025 Part 17 | Assesses suspended material or optical cloudiness in water. | A higher result indicates more suspended or light-scattering material and may signal inadequate clarification, contamination or process carryover. |
| Turbidity | APHA 2130-B / IS 3025 Part 10 | Assesses suspended material or optical cloudiness in water. | A higher result indicates more suspended or light-scattering material and may signal inadequate clarification, contamination or process carryover. |
| Biochemical Oxygen Demand | IS 3025 Part 44 | Assesses organic, oxidisable or hydrocarbon-related loading in water. | A higher result indicates greater loading under the selected method and may affect treatment, discharge or process suitability. |
| Chemical Oxygen Demand | IS 3025 Part 58 | Assesses organic, oxidisable or hydrocarbon-related loading in water. | A higher result indicates greater loading under the selected method and may affect treatment, discharge or process suitability. |
| Microbial Examination | IS 1622 | Assesses the selected microbiological indicator or organism group. | Detection or a higher count indicates greater microbiological loading; interpretation must follow the applicable water-use requirement and sampling controls. |
| Total Organic Carbon | APHA 23rd Edition 5310B | Assesses organic, oxidisable or hydrocarbon-related loading in water. | A higher result indicates greater loading under the selected method and may affect treatment, discharge or process suitability. |
Before dispatch
Sample-submission guidance
- Use a clean, secure and appropriately labelled container.
- Provide the sample identity, fluid grade and equipment or system details where applicable.
- Share operating hours, maintenance history, the suspected problem and required specification where available.
- Contact Chem-Tech before dispatch so the laboratory can confirm the sample quantity, container and selected testing scope.

Reporting and interpretation
The report records results and methods for the agreed scope. Customer-supplied limits or specifications can be considered when provided before testing.
Results should be reviewed with equipment history, operating conditions and previous data; a laboratory result alone does not guarantee a root-cause diagnosis or remaining service life.
