Environmental Field Sampling and Testing Services

Reliable laboratory results begin with properly collected and handled samples.

Environmental Testing and Laboratories Company (ETLCO) provides environmental field sampling, sample pickup, and on-site testing support for industrial facilities, utilities, contractors, and environmental projects across Saudi Arabia.

Our field teams support the collection of water, wastewater, soil, sludge, sediment, and waste samples. Each sampling program is coordinated around the project objectives, site conditions, analytical requirements, and agreed schedule.

Through close collaboration between project management, sample coordinators, and laboratory personnel, we help clients organize sampling activities and deliver samples for analysis within the required handling and holding-time conditions.

Field Support Built Around Your Project

A successful sampling event requires more than collecting a sample. Site access, sampling locations, containers, preservation, transport, and laboratory readiness all need to be coordinated.

ETLCO’s field support helps clients:

• Plan sampling activities around operational and project schedules.

• Select sampling approaches suited to the material and testing objectives.

• Coordinate access to designated sampling locations.

• Confirm containers, sample quantities, and preservation requirements.

• Document sample identification and collection details.

• Maintain traceability from collection through laboratory receipt.

• Arrange sample pickup and transport under agreed conditions.

Our Environmental Sampling Services

Groundwater Well Sampling

ETLCO provides groundwater sampling to support environmental monitoring, baseline studies, and contamination investigations.

The sampling approach is selected according to well construction, groundwater conditions, target parameters, and project requirements. Field observations and relevant sampling details are recorded to support interpretation of the analytical results.

Dewatering Well Sampling

We collect samples from dewatering wells and associated discharge points to support water quality assessment during construction and groundwater control activities.

Testing requirements can be aligned with the project’s intended discharge route, treatment arrangements, and specified monitoring criteria.

Surface Water Sampling

ETLCO supports sampling from rivers, lakes, reservoirs, channels, and other surface water bodies.

Sampling locations and timing are planned around the study objectives, site accessibility, and conditions that may influence the results. Services support baseline assessments, periodic monitoring, and investigations into suspected contamination.

Industrial Wastewater Sampling

We collect industrial wastewater samples from designated process, treatment, and discharge locations.

Sampling can support characterization of wastewater, evaluation of treatment performance, and comparison with applicable project criteria. Grab or composite sampling is considered according to the target parameters and monitoring requirements.

Sanitary Wastewater Sampling

ETLCO provides sampling of sanitary wastewater and treated effluent to support treatment plant monitoring and operational assessments.

Sampling points may include influent, intermediate treatment stages, and final effluent, depending on the agreed scope.

Soil Sampling

We collect soil samples to support environmental site assessments, contamination investigations, and remediation verification.

Sampling locations, depths, and collection procedures are defined according to the purpose of the study and the expected distribution of contaminants.

Sludge and Sediment Sampling

ETLCO provides sampling of treatment sludge and environmental sediments for physical and chemical analysis.

The collection approach accounts for material consistency, access, sampling depth, and analytical requirements. These services support characterization, contamination assessment, and waste management evaluations.

Solids and Non-Aqueous Waste Sampling

We support the sampling of solid materials and non-aqueous waste streams associated with industrial processes and environmental projects.

The sampling plan considers material variability and the need to obtain samples appropriate to the assessment objective, while preserving the characteristics relevant to laboratory testing.

Hazardous Industrial Waste Sampling

ETLCO provides sampling support for hazardous industrial waste characterization, subject to review of the material’s known hazards and site conditions.

Before mobilization, our team reviews available process information and safety documentation to confirm the sampling approach, required equipment, and handling arrangements.

Drinking Water Network Sampling

We collect samples from designated points within drinking water networks to support water quality monitoring and investigations.

Sampling procedures, containers, and preservation requirements are selected according to the requested chemical or microbiological analyses.

Seawater Intake, Desalination, and Outfall Sampling

ETLCO supports sampling at seawater intakes, desalination facilities, and marine discharge locations.

Programs can include feedwater, process streams, product water, brine, and receiving-water samples, according to the agreed scope. Sampling locations and timing are coordinated with facility operations, access arrangements, and marine conditions.

On-Site Measurements and Field Testing

Some water quality parameters are best assessed at the sampling location because they can change during storage and transport.

Depending on the project scope and equipment availability, field measurements may include parameters such as temperature, pH, electrical conductivity, dissolved oxygen, and other specified indicators.

Required measurements, methods, and reporting arrangements are confirmed before mobilization.

Sample Pickup and Laboratory Coordination

Coordinated Collection and Delivery

ETLCO offers sample pickup for client-collected samples, with arrangements agreed according to location, sample type, and laboratory requirements.

Our coordinators help confirm that samples are accompanied by the necessary information and delivered under suitable conditions. For time-sensitive analyses, collection and transport schedules are planned around the applicable holding times.

Sample Identification and Chain of Custody

Clear identification and documentation support traceability throughout the sampling and testing process.

Depending on the project, records may include:

• Sample identification and sampling location.

• Collection date and time.

• Sample type and requested analyses.

• Relevant field observations and measurements.

• Preservation details.

• Chain-of-custody information and sample handover records.

Containers, Preservation, and Transport

Container selection and preservation depend on the requested analysis. Our team provides guidance before sampling so that collection and transport arrangements are appropriate for the tests.

Sample condition is reviewed upon laboratory receipt, and any issue that may affect analysis is addressed through the laboratory’s acceptance process.

Support for Routine Monitoring and Special Projects

ETLCO’s field services support:

• Environmental baseline studies.

• Routine facility monitoring.

• Groundwater and dewatering assessments.

• Water and wastewater treatment investigations.

• Contaminated land and remediation projects.

• Waste characterization programs.

• Drinking water quality monitoring.

• Desalination and marine monitoring activities.

Additional sampling requirements can be discussed with our team and assessed against project needs and site conditions.
