ABSENCE WITHOUT LEAVE, DESERTION, AND ADMINISTRATION OF PERSONNEL INVOLVED IN CIVILIAN COURT PROCEEDINGS recovery improvement of 18 percentage points (p = 0.0001); and (2) a multi-laboratory side-by-side analysis that resulted in an averageAnother improvement I was glad to see is the internal standard (IS) addition. With method 525.3 you will now add the internal standard to the final extract not in the sample prior to extraction as stated in 525.2. I was glad to see this change as I felt that the addition of the internal standard to the sample normalizes the data and accounts for all losses without the impact when the IS was added prior to extraction. So why is this an improvement? You will have improved quality that will demonstrate the losses throughout the sample extraction, drying and concentration steps. This means you need a more robust sample preparation procedure and I prefer to use an automated system as much as possible. By implementing automation throughout the 525.3 procedure, you limit the manual interactions with each critical technique and in turn, create consistent results throughout the sample batch which will make being within your method limits that much easier.

As discussed with EPA Method 536, EPA Method 523 can be used for the determination of atrazine and simazine in finished drinking water. EPA Method 523 and the approved EPA Method 525.2, Revision 2.0 (USEPA 1995) are both GC/MS methods; however, one of the advantages that EPA Method 523 offers relative to the approved method is the use of solid reagents, ammonium acetate and 2-chloroacetamide, for sample preservation instead of hydrochloric acid. This allows sample bottles to be prepared in the laboratory prior to shipment to the field, thus eliminating the need to ship a hazardous liquid acid. The method performance characteristics of EPA Method 523 were compared to the characteristics of the approved EPA Method 525.2, Revision 2.0 for atrazine and simazine. EPA has found that EPA Method 523 is equally effective for measuring atrazine and simazine concentrations, relative to the approved method. The basis for this determination is discussed in Smith and Wendelken (2012a). Therefore, EPA is approving EPA Method 523 for EPA is approving 10 methods that are equally effective relative to methods previously promulgated in the regulations. By means of this notice, these 10 methods are added to Appendix A to Subpart C of 40 CFR Part 141. A.
