Purgeable organic compounds

The Clean Water Act (1972) requires discharge limits to be set on industrial and municipal wastewater, and these analyses are outlined in the National Pollution Discharge Elimination System for the 600 Series Methods. Method 624 covers the analysis of purgeable organic compounds Method 625 covers the analysis of 81 bases, neutrals, and acids Method 613 describes the analysis of dioxins and furans. 

To satisfy the Resource Conservation and Recovery Act (1977) and its amendment for hazardous and solid waste (1984), the 80(K) Series Methods have been designed to analyze solid waste, soUs, and groundwater. In particular, methods 8240/8260 require the use of a purge-and-trap device in conjunction with packed or capillary GC/MS, respectively, for the analysis of purgeable organic compounds. Methods 8250/8270 concern analyses for the less-volatile bases, neutrals, and acids by GC/MS after extraction from the matrix by an organic solvent. 

Bromofluorobenzene (BFB) is used to establish tuning performance prior to the analysis of purgeable organic compounds, and decafluorotriphenylphosphine (DFTPP) is used prior to the analysis of bases, neutrals, and acids (Figure 41.1).

A study by Gibs et al. (1990) found that monitoring field water-quality parameters for stability is not a reliable indicator of when to collect a representative sample for purgeable organic compounds (POCs), such as chlorinated alkanes, alkenes and aromatics. For these types of compounds, the researchers suggest direct monitoring of POC concentrations.
