Sediments Testing – METS Laboratories
At METS Laboratories, we specialize in comprehensive sediments testing to assess the physical, chemical, and biological composition of sediment samples across diverse matrices. Sediments act as both a sink and a source of contaminants in aquatic environments, making them critical indicators of ecosystem health, environmental compliance, and potential human exposure risks.
Our sediment testing services are designed to meet regulatory standards, support pollution monitoring, and ensure environmental sustainability for industries, environmental agencies, and research institutions. With state-of-the-art instrumentation, standardized methodologies, and a commitment to ISO/IEC 17025: 2017 quality assurance, METS delivers accurate, timely, and actionable sediment analysis results.
Why Sediments Testing Is Important?
Sediment testing plays a vital role in environmental monitoring and risk assessment. Here’s why:
• Pollution Detection: Sediments accumulate heavy metals, pesticides, hydrocarbons, and other persistent contaminants that may not be visible in water samples alone.
• Regulatory Compliance: National and international environmental regulations often require sediment assessments for discharge permits, environmental impact assessments (EIAs), and site remediation projects.
• Aquatic Health Assessment: Sediment quality directly impacts benthic organisms and aquatic food chains. Poor sediment conditions can lead to biodiversity loss and ecosystem imbalance.
• Human Health Protection: Toxic compounds in sediments can bioaccumulate through the food chain, posing health risks to humans through seafood consumption and water use.
• Sustainable Development: Baseline and periodic sediment testing support informed land use planning, dredging activities, port operations, and industrial development.
What We Test?
• Grain size distribution (sand, silt, clay)

Frequently Asked Questions
What is the ideal sample size for sediment testing?
It depends on the intended use. For agricultural land, soil should be tested annually or bi-annually. For industrial and construction sites, testing is essential before development and post-remediation.
How should sediment samples be stored and transported?
Samples should be stored in clean, inert containers (e.g., glass or HDPE), kept cool (≤4°C), and shipped within 24–48 hours to prevent degradation of organics and microbial content.
Can METS Laboratories conduct sampling on-site?
Yes, we offer turnkey services including trained personnel for sediment sampling as per ISO 5667-12 and EPA methods.
How long does it take to get results?
Standard turnaround time is 7–10 working days. Urgent testing can be completed within 48–72 hours with prior notice.
Are METS reports acceptable for legal and regulatory submissions?
Absolutely. Our results are generated under ISO/IEC 17025: 2017 accredited protocols, accepted by most regulatory agencies.
Can you test sediments from marine environments?
Yes, we test sediments from marine, estuarine, riverine, and freshwater bodies, as well as from industrial discharge zones and dredged material.
Do you provide risk assessment or remediation consultancy?
Yes, we offer interpretation of test data, environmental risk assessments, and strategic recommendations for remediation or further investigation.
What industries need sediment testing most frequently?
Petrochemical, ports and harbours, mining, shipyards, power generation, agriculture, and infrastructure development sectors commonly require sediment testing.
