GSAB – Global Standard Accreditation Board provides independent and impartial accreditation to Environmental Testing Laboratories in accordance with ISO/IEC 17025. Our accreditation ensures laboratories demonstrate technical competence, reliable analytical methods, environmental monitoring accuracy, and regulatory compliance capability.
What Do Environmental Testing Laboratories Do?
Environmental testing laboratories analyze environmental samples to assess pollution levels, regulatory compliance, and environmental safety.
They evaluate:
-Air quality
-Water and wastewater quality
-Soil contamination
-Industrial emissions
-Hazardous waste
-Environmental impact parameters
Environmental laboratories support industries, government agencies, municipalities, and environmental management programs.
Typical Environmental Tests Performed
Depending on their scope, laboratories may conduct:
Water & Wastewater Testing
pH, turbidity, conductivity
Biological Oxygen Demand (BOD)
Chemical Oxygen Demand (COD)
Total Suspended Solids (TSS)
Heavy metals analysis
Nutrient analysis (nitrate, phosphate, ammonia)
Microbiological water testing
Air Testing
Particulate matter (PM10, PM2.5)
Stack emission analysis
Volatile Organic Compounds (VOCs)
Gaseous pollutants (SO₂, NOx, CO, CO₂)
Soil Testing
Heavy metals
Pesticide residues
Hydrocarbon contamination
Nutrient and mineral analysis
Hazardous Waste Testing
Toxicity characteristic leaching procedure (TCLP)
Chemical contaminant profiling
GSAB verifies method validation, sampling control, traceability, measurement uncertainty, and quality assurance practices.
