Element-Specific Content Testing Standards

Standards for element-specific content testing of wastewater provide standardized test methods for the determination of dissolved and total recoverable element quantities. With standards grouped by those applicable to the testing for a single element, those addressing the testing for multiple elements through a single method, and those which instead test for a compound (or a group of them), these standards provide part of the foundation on which treatment methods are judged upon, and thus must be reliable between labs and technicians.
