Water Quality Testing and Analysis

Understand your water quality. Identify contaminants. Make informed decisions for your operations and the environment.

Environmental Testing and Laboratories Company (ETLCO) provides water sampling and laboratory analysis to evaluate the chemical, physical, and microbiological characteristics of water. As an experienced water testing company, ETLCO supports clients with testing programmes tailored to their operational and environmental requirements.

Our services cover drinking water, wastewater, groundwater, seawater, and other water matrices. We help industrial operators, water treatment facilities, environmental consultants, and agricultural clients assess water quality, investigate contamination, and evaluate suitability for intended uses.

Each testing programme is tailored to the water source, project objectives, and applicable assessment criteria.

Water Testing for Your Application

Water quality requirements vary according to how the water will be used, treated, reused, or discharged. ETLCO helps clients select relevant tests and obtain results that support practical decisions. Our water inspection and laboratory testing services help assess water conditions, identify potential contamination, and support informed water management decisions.

Our services support:

• Drinking water assessment: Evaluate selected chemical, physical, and microbiological indicators in water supplies, storage systems, and distribution networks.

• Wastewater monitoring: Characterise industrial and sanitary wastewater, assess treatment performance, and support discharge or reuse evaluations.

• Groundwater investigations: Establish baseline conditions, investigate potential contamination, and monitor changes over time.

• Seawater assessment: Support coastal environmental monitoring and assessments associated with seawater intakes, desalination facilities, and outfalls.

• Industrial water management: Assess water quality against requirements relevant to specific processes and operational needs.

• Agricultural applications: Evaluate selected water quality parameters relevant to irrigation and agricultural use.

Our Water Quality Testing Parameters

ETLCO offers a broad range of analyses, with the testing scope selected according to the sample matrix and intended application.

Physical and general chemical parameters

• pH

• Turbidity

• Dissolved Oxygen (DO)

• Total Dissolved Solids (TDS)

These measurements support the characterisation of water and the investigation of changes in its quality.

Organic load indicators

• Biochemical Oxygen Demand (BOD)

• Chemical Oxygen Demand (COD)

These parameters support wastewater characterisation and the assessment of treatment performance.

Nutrients and dissolved ions

• Nitrates

• Phosphates

• Chlorides

Testing supports the evaluation of nutrient levels and dissolved constituents relevant to environmental monitoring, treatment, and intended water use.

Metals and organic contaminants

• Heavy Metals

• Volatile Organic Compounds (VOCs)

• Semi-Volatile Organic Compounds (SVOCs)

• Total Petroleum Hydrocarbons (TPH)

• Total Chlorinated Hydrocarbons (TCH)

• Trihalomethanes (THMs)

• Pesticides

The target compounds, analytical methods, and reporting limits are defined according to the project requirements and suspected contamination sources.

Microbiological parameters

• Microbial Contaminants

Microbiological testing targets agreed organisms or indicator groups to support water quality monitoring, contamination investigations, and treatment assessments.

From Sampling to Clear Results

ETLCO combines sampling, laboratory analysis, and interpretation of results to provide a coordinated water testing service.

1. Review your requirements: Define the water source, intended use, testing objectives, and relevant specifications.

2. Coordinate sampling: Establish sample collection arrangements, suitable containers, preservation requirements, and transport conditions.

3. Perform laboratory analysis: Analyse the agreed parameters using methods appropriate to the water matrix and project scope.

4. Report and interpret findings: Present results clearly and, where agreed, compare them with specified limits or assessment criteria.

Sampling locations, timing, and sample handling are considered as part of the programme to help obtain results relevant to your objectives.

Data That Supports Better Water Management

Whether you need routine monitoring or an investigation into unexpected water quality changes, ETLCO provides analytical information to support:

• Identification of selected contaminants.

• Evaluation of water treatment performance.

• Assessment of suitability for a specified use.

• Review of discharge and reuse requirements.

• Planning of corrective actions and follow-up monitoring.

• Environmental reporting and compliance assessment.

Results reflect the samples collected and the parameters tested. A testing programme aligned with the intended use provides a stronger basis for evaluating water quality and tracking changes over time.

Discuss Your Water Testing Requirements

Send ETLCO details of your water source, intended use or discharge route, sample quantity, required parameters, and any applicable project specifications. Include information about suspected contamination or recent changes in water quality, where available.

Our team will help define the testing scope, confirm sampling requirements, and prepare a technical and commercial proposal.

For clients seeking local testing services, ETLCO can also address location-specific requirements for water quality testing in Dammam and water testing laboratory in Riyadh, subject to service availability in those locations.
