Abstract:

The Method Detection Limit (MDL) procedure at CFR40 Part 136 Appendix B is currently used for almost all determinations of detection limits for EPA analytical methods, and is mandated for wastewater analysis under Part 136. The procedure has several failings, including: Lack of any consideration of non-zero blanks; lack of any consideration of long term variability; failure to accommodate EPA methods which censor data at some level; and failure to accommodate non-normal data or non-constant variance. These weaknesses can result in incorrect determinations of the detection limit, and prompted EPA to establish a Federal Advisory Committee to develop an improved procedure.
