ASTM D5790 - 18

Overview

ASTM D5790 - 18 is a critical standard that outlines the test method for measuring purgeable organic compounds (POCs) in water using capillary column gas chromatography/mass spectrometry (GC/MS). This standard is essential for laboratories and industries involved in environmental testing, ensuring accurate detection and quantification of organic contaminants in water samples.

Key Requirements

The standard specifies the procedures and methodologies necessary for the effective measurement of POCs. Key requirements include:

• Preparation of water samples to ensure accurate representation of the analytes.
• Calibration of the GC/MS system to achieve reliable results.
• Use of appropriate internal standards to enhance measurement accuracy.
• Adherence to specific temperature and pressure conditions during analysis.
• Documentation of all procedures and results to maintain traceability.

Implementation Benefits

Implementing ASTM D5790 - 18 provides numerous benefits for organisations involved in water quality testing:

• Enhanced Accuracy: The standardised methodology ensures that results are reproducible and reliable, which is crucial for compliance with environmental regulations.
• Improved Detection Limits: The use of advanced GC/MS techniques allows for the detection of low concentrations of organic compounds, which is vital for assessing water safety.
• Regulatory Compliance: Adhering to this standard helps organisations meet local and international regulations regarding water quality and safety.
• Quality Assurance: Following ASTM D5790 - 18 aids in establishing a robust quality control system within laboratories, enhancing overall operational efficiency.

Compliance Value

Compliance with ASTM D5790 - 18 is essential for organisations aiming to ensure the safety and quality of water resources. The standard supports compliance with various regulatory frameworks, including:

• The Water Framework Directive (WFD) in the European Union.
• Environmental Protection Agency (EPA) guidelines in the United States.
• Local environmental regulations that govern water quality standards.

By implementing the procedures outlined in this standard, organisations can demonstrate their commitment to environmental stewardship and public health. Furthermore, compliance with ASTM D5790 - 18 can enhance an organisation's reputation and credibility in the marketplace, fostering trust among stakeholders and customers.

Conclusion

ASTM D5790 - 18 serves as a vital tool for laboratories and industries focused on the accurate measurement of purgeable organic compounds in water. By following this standard, organisations can achieve high levels of accuracy, ensure compliance with regulatory requirements, and contribute to the protection of water resources.
