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.
As the voice of the U.S. standards and conformity assessment system, the American National Standards Institute (ANSI) empowers its members and constituents to strengthen the U.S. marketplace position in the global economy while helping to assure the safety and health of consumers and the protection of the environment.
