ASTM D6349 Semi Volatile Organic Compounds SVOC Test in Soil
The ASTM D6349 semi-volatile organic compounds (SVOCs) test is a critical procedure for assessing the contamination levels of volatile and semi-volatile organic substances in soil. This testing method plays an essential role in environmental quality management, compliance with environmental regulations, and risk assessment for contaminated sites. SVOCs are chemicals that remain in a liquid or solid state at room temperature but vaporize easily under normal conditions. They can be toxic, carcinogenic, or mutagenic, posing significant risks to human health and the environment.
The ASTM D6349 test involves extracting SVOCs from soil samples using a solvent-based approach followed by gas chromatography/mass spectrometry (GC/MS) analysis for identification and quantification. This process ensures precise measurement of the compounds, providing reliable data that can be used to evaluate contamination levels and guide remediation efforts.
Quality managers and compliance officers must understand the importance of this test in ensuring environmental standards are met. By using ASTM D6349, they can demonstrate their commitment to sustainable practices and regulatory compliance. R&D engineers also play a crucial role in developing new methods and technologies that improve the accuracy and efficiency of SVOC testing.
The test is particularly important for sites undergoing remediation or those suspected of contamination due to industrial activities, waste disposal, or other sources. Proper soil quality assessment helps identify potential risks early on, allowing for targeted interventions before they escalate into larger issues.
For procurement professionals, ensuring that suppliers adhere to strict environmental standards is vital. By insisting on ASTM D6349 testing results, companies can maintain high ethical and environmental standards throughout their supply chains.
Scope and Methodology
| Scope of ASTM D6349 Test | Description |
|---|---|
| Extraction Solvent | Pure pentane or a mixture of pentane and heptane in a 1:2 ratio. |
| Solvent Extraction Time | Soil samples are extracted for at least six hours, ensuring thorough dissolution of SVOCs. |
| Sample Volume | Approximately 50 grams of soil per sample to ensure accurate extraction and analysis. |
The ASTM D6349 test begins with the collection of representative soil samples from various depths within a contaminated area. These samples are then transported to our laboratory for processing, where they undergo rigorous quality control checks before undergoing solvent-based extraction. The extracted SVOCs are concentrated and purified, ready for analysis via gas chromatography/mass spectrometry (GC/MS).
During the GC/MS analysis, each compound is identified based on its unique retention time and mass spectrum signature. Quantification is achieved by comparing the peak area of the target compounds to those of known standards. This ensures precise measurement and accurate reporting.
The entire process adheres strictly to ASTM D6349 guidelines, ensuring consistent results across multiple samples and sites. Our laboratory uses state-of-the-art equipment calibrated according to international standards (ISO/IEC 17025) to maintain high levels of accuracy and precision.
