AB  - The use of a large volume polyurethane foam (PUF) sampler was validated for rapid 
      extraction of persistent organic pollutants (POPs), such as polychlorinated 
      dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), in raw water and treated water 
      from drinking water plants. To validate the recovery of target compounds in the 
      sampling process, a (37)Cl-labeled standard was spiked into the 1st PUF plug 
      prior to filtration. An accelerated solvent extraction method, as a pressurized 
      liquid extractor (PLE), was optimized to extract the PUF plug. For sample 
      preparation, tandem column chromatography (TCC) clean-up was used for rapid 
      analysis. The recoveries of labeled compounds in the analytical method were 
      80-110% (n = 9). The optimized PUF-PLE-TCC method was applied in the analysis of 
      raw water and treated potable water from seven drinking water plants in South 
      Korea. The sample volume used was between 18 and 102 L for raw water at a flow 
      rate of 0.4-2 L min(-1), 95 and 107 L for treated water at a flow rate of 1.5-2.2 
      L min(-1). Limit of quantitation (LOQ) was a function of sample volume and it 
      decreased with increasing sample volume. The LOQ of PCDD/Fs in raw waters 
      analyzed by this method was 3-11 times lower than that described using large-size 
      disk-type solid phase extraction (SPE) method. The LOQ of PCDD/F congeners in raw 
      water and treated water were 0.022-3.9 ng L(-1) and 0.018-0.74 ng L(-1), 
      respectively. Octachlorinated dibenzo-p-dioxin (OCDD) was found in some raw water 
      samples, while their concentrations were well below the tentative criterion set 
      by the Japanese Environmental Ministry for drinking water. OCDD was below the LOQ 
      in the treated drinking water.
