Comprehensive Environmental Testing & Monitoring Services

Our accredited laboratory provides accurate, reliable, and regulatory-compliant testing services to support environmental approvals, monitoring, and operational decision-making across Sri Lanka.

Water Analysis

We provide comprehensive water quality analysis for surface water, groundwater, raw water, well water, and treated water from drinking water treatment plants. CETEC is also equipped to analyze industrial process water and specialty water streams in accordance with methods prescribed by relevant regulatory authorities.

All laboratory analyses are carried out by qualified laboratory technologists and chemists, under the supervision of the Laboratory Manager and Senior Technical Managers. Testing is conducted strictly in accordance with APHA Standard Methods and other authority-approved analytical procedures, ensuring accuracy, traceability, and regulatory acceptance.

Wastewater Analysis

We perform wastewater and industrial effluent quality analysis for a wide range of sectors to support Environmental Protection Licence (EPL) compliance, system performance evaluation, and operational troubleshooting.

Our services include:

Routine wastewater monitoring for regulatory submissions
Performance assessment of existing wastewater treatment plants
Efficiency evaluation of individual treatment units
Support for chemical dosage optimization and process control

Our analytical results assist clients in achieving stable operation, improved treatment efficiency, and consistent regulatory compliance.

Noise Measurement

CETEC conducts environmental and occupational noise monitoring for industrial facilities, construction sites, and infrastructure projects using CEA-approved Type A noise meters with octave bands features.

Measurements include Leq noise levels with A, C, and Z frequency weighting, under fast and slow time weighting, in accordance with regulatory guidelines. The results are suitable for EIA/IEE studies, EPL compliance, and environmental impact assessments.

Industrial & Ambient Air Quality Testing

We provide industrial, ambient, indoor, and stack air quality monitoring services to assess emissions, occupational exposure, and environmental impacts in compliance with national regulations.

What We Measure

Ambient & Indoor Air Quality
Stack and Fugitive Emissions
Particulate Matter (PM₂.₅, PM₁₀, TSPM, TVOC)
Gaseous Pollutants (SO₂, NOₓ, CO, O₃, etc.)

Our monitoring programs are designed to determine what to measure, where to measure, and how frequently, ensuring meaningful data for regulatory reporting and mitigation planning. CETEC issues authority-compliant technical reports accepted by regulatory bodies.

Ground Vibration Analysis

How long does it take to receive the test report?

CETEC issues laboratory test reports within ten (10) working days from the date of sample receipt or completion of field sampling, provided that:

Samples are received in acceptable condition, and
All required information and payments (if applicable) are completed.

In cases where additional analysis, repeat testing, or complex parameters are required, the reporting timeline will be communicated to the client in advance.

Are my test results confidential?
