ASTM D8574

ASTM D8574 is a laboratory standard for determining select pesticides and herbicides in water using liquid chromatography tandem mass spectrometry (LC-MS/MS). It provides a structured analytical approach for identifying and measuring targeted contaminants in water samples with high sensitivity and specificity. For laboratories, utilities, and environmental testing programs, this standard helps support more consistent data generation, method selection, and compliance-focused monitoring when pesticide or herbicide residues may be a concern.

What is ASTM D8574?

ASTM D8574 describes a test method used to determine select pesticides and herbicides in water by LC-MS/MS. The standard is centered on analytical measurement rather than treatment or product performance, making it relevant to laboratories that need a defined procedure for targeted contaminant analysis. By outlining a recognized test method, ASTM D8574 helps establish a common technical basis for sample evaluation, result reporting, and comparison across testing programs using mass spectrometric detection.

Where is ASTM D8574 used?

This standard is commonly used in water testing settings where selected pesticide and herbicide residues need to be measured with precision. It may be applied by environmental laboratories, water quality programs, and other analytical teams working with potable water, source water, or related water samples. ASTM D8574 is especially useful where LC-MS/MS instrumentation is part of the workflow and where targeted contaminant testing supports routine monitoring, investigations, or documentation for regulated and quality-controlled water analyses.

Why is ASTM D8574 important?

ASTM D8574 matters because it helps bring consistency to the measurement of select pesticide and herbicide residues in water. A recognized standard test method supports more reliable comparison of results between laboratories and across projects, which can be important for compliance work, procurement decisions, and quality control. It also helps reduce uncertainty in analytical reporting by providing a clear technical framework for LC-MS/MS-based testing of targeted compounds in water.
