SW-846 Update IV Methods offered

Environmental NEWS - Fall 2009

Early in 2008, USEPA notified the regulated community of the availability of Final Update IV to the Third Edition of SW-846, Test Methods for Evaluating Solid Wastes. State regulators are implementing Update IV Methods in various ways, so it’s important that clients check with their regulators to confirm their requirements. Currently, at least two states, North Carolina Division of Water Quality and South Carolina Department of Health and Environmental Control, are requiring laboratories to reference Update IV of SW-846, where applicable. Several methods in use at Lancaster Laboratories were among 23 methods revised as part of the update. In addition, Lancaster Labs has also validated several new techniques that were published in Update IV. A complete list of the Update IV Methods currently available at Lancaster Labs is given below, but it’s important to note that Lancaster Labs only performs the new versions with client approval since some agencies are still requiring the use of earlier versions.
