About This Item
ASTM D3223 is the ASTM standard titled Standard Test Method for Total Mercury in Water, used to guide measurement of mercury levels in water samples. It provides a clear technical reference for laboratories and water-quality professionals who need consistent test results for monitoring, reporting, or compliance activities. By defining a common test method, this standard helps support reliable data handling and more comparable mercury analysis across routine testing programs.
Purpose of ASTM D3223
The purpose of ASTM D3223 is to establish a standardized approach for determining total mercury in water. As a test method, it is intended to support consistent laboratory practice and reduce variation in results from one analysis to another. This is important when mercury data are used for environmental monitoring, regulatory review, or internal quality control. The standard helps align testing work with a recognized ASTM framework for water analysis.
Common use cases of ASTM D3223
This standard is commonly used in laboratories that analyze water samples for mercury content, including environmental testing and water-quality assessment work. It may be applied when evaluating surface water, wastewater, or other water matrices where total mercury measurements are needed. ASTM D3223 is also useful in sampling and testing workflows where repeatable analytical results are important for reporting, compliance documentation, or comparison between batches, sites, or test periods.
Why ASTM D3223 matters
ASTM D3223 matters because mercury testing in water often requires dependable, defensible results. A recognized test method helps improve consistency in procurement, laboratory selection, and quality control programs. It can also reduce ambiguity when organizations need to compare data across different facilities or testing events. For teams responsible for compliance or environmental decision-making, ASTM D3223 provides a practical reference that supports more confident interpretation of total mercury results.
