This revision of Method 1668 (Method 1668B; the 'Method') revises EPA Method 1668A to replace single-lab quality control (QC) acceptance criteria with interlaboratory criteria, and make other changes described below. Method 1668B was developed by the Office of Waters Office of Science and Technology (OST) for use in Clean Water Act (CWA) programs. Method 1668B is based on the results of an interlaboratory validation study, and a peer review of that study. Method 1668B, and the validation study report, Method 1668A Interlaboratory Validation Study Report (EPA-821-08-021), are available at EPA's CWA methods website at www.epa.gov/waterscience/methods.
