Tables of Approved Methods and Where They Can Be Found in Standard Methods

August 8, 2013
Based on the Federal Register notice of May 31, 2013 containing the Expedited Approval of Alternate Test Procedures under the Safe Drinking Water Act, the 22nd Edition now contains methods approved for drinking water as well as wastewater. In order to help Standard Methods users determine which methods are USEPA-Approved and where they can be found, the following tables are provided. One table contains methods approved under the Clean Water Act and the other contains methods approved under the Safe Drinking Water Act.

Many thanks to former Part Coordinator Ed Askew for developing these tables.

If you have any questions, contact the Standard Methods Manager at nedman@awwa.org.
