This presentation is to update the NEMC attendees the current RCRA Methods development activities and our path forward. Topics will include:

Update VI – final steps
• Inorganic Methods: 1340 and 3050C – completed
• Organic Methods: 8260D and 8270E – completed
• LEAF Methods: 1313, 1314, 1315, 1316 and the Users’ Guide – final publication anticipated mid-2019

Update VII – phased approach
• Method 8327: Per- and Polyfluoroalkyl Substances (PFAS) in Groundwater, Surface Water, and Wastewater by Multiple Reaction Monitoring (MRM) LC/MS/MS
• Method 8328: Solid Phase Extraction and Analysis of PFAS in Aqueous and Solid Samples by High-Performance LC/MS/MS Using Isotope Dilution and Internal Standardization
• Method 3050C: Acid Digestion of Sediments, Sludges, and Soils
• Ignitability: revisions to flashpoint methods – 1010B and 1020C, revisions to sampling and stack emissions methods – 0010, 0011, 0020, 0023A, and 0051
