MONS 220602 ANALYSIS OP LANDFILL WELL WATER SAMPLES FOR TOTAL PHENOLS TETRACI(LOROD1!!ESZO*-OIOx:N AND polyciiloronated biphenyls Eight (!) water samples were submitted to the Dayton Laboratory for analyses to determine t!.c possible presence and concentra tions of total phenols, polychlorinated biphenyls (PCI) and tctrachlorodibcnio-p-diox ins (TCOD). Total Phenols The presence ar.d concentration of phenol in each of the water samples was determined and measured by typical wet chemistry techniques 11], An independent phenol standard was also analyzed i:z quality assurance. The results of these analyses are shown m Table 1. TABLE 1. ANALYSIS OF LANDFILL WELL NATi?

The combined extracts (sample and container) of each sample were dried and evaporated to 1-mL. Each 1-*L sample was analyzed by a capillary gas chromatography/mass spectrometry (CC/MS) technique. The MS was operated in the Selected Ion Monitor mod* (SIN) to enhance sensitivity and decrease possible interferences. The SIN mod* monitors two ions for each isomer class of PCI's (number of chlorine atoms on the biphenyl molecule). Known PCI standards were analyzed to quantitate sample concentrations. Spikes and duplicates of the samples were run under similar analytical con ditions for quality assurance. Results of these analyses are shown in Table 2. Tetrachlorodibenzo-p-dioxins (TCOOs) Eight water samples were received for the analysis of tetrachlorcdibenzo-g-dioxins (TCDO). Two separate 1-liter samples were provided fror. each sit*. On* of the 1-liter bottles for each site was used for the analysis with the other bottle being set aside in the event that soma problem or difficulty occurred in the original analysis. The samples wer* analysed by taking one of the 1-liter bottles and placing S00 mL of the water into each of two 1-liter bottles. One of the $00 mb aliquots was then used for the analysis with the other aliquot used as a replicet* or for spiking with native (unlabeled) 2.3,7.t-TCDO. 200 mL of petroleum ether wee thee added to the original sample bottle end the ooatents wars shaken for 30 seconds to sstrset sny TCOOs which msy sdhers to the glass. During this time, ell the 500 mb aliquots were spiked with '*Cu-labeled 2,3.7.1-tcdd and various $00 mb aliquots wore spiked with native 2,1,7.I-TCDO. 100 mb of the petroleum ether from the original aampla bottla was then plaqpd into each of tho bottles containing the $00 mb aliquots. 2 HONS 220404 TABLE 2.

The petroleum ether layer was then washed with base followed by sulfuric acid. Column chromatography of the concen trated petroleum ether vkj carried out on a Woelm Basie alumina column collecting the fraction that elutes with the Sot CH,C1,/ Hexane fraction, concentrating to 2$ uL and submitting this aampia for GC/M5 analysis. The CC/MS analysis was carried out on a Hewlett-Packard 5SISB CC/MS system. The chromatograph was equipped with a J and w 30 meter SE-S4 capillary column. The mass spectrometer was operated in the selected ion monitoring mode following one ion character istic of the labeled TCDD (m/z 334) and three ions characteristic of native TCDD (r,/z 257, 320, 322). Cuantitation was carried out by ratioinq the response of the native TCDD to the labeled TCDD. The results of the analyses are qiven in Table 3. Sample A15 showed very serious interferences so a different workup of this sample was carried out usinq 100 mL of water at the outeet rather than the 500 mL and alao usinq an initial alumina column clean up step prior to the base end acid washes. The results qiven as *ND* mean none detected at a detection limit qiven in parenthesis. This detection limit depends on the interferences present end sample recovery end thus vsries from sample to sample. The blank is representative of the lower detection limit if there were no interferences. A TCDD was found in the samples from wells 2A and 2B and in the 1,3,5,l-TCDD. The chrometographie traces for the analysis of well 2A is given in Figure 1. The ions being monitored are char acteristic of tike molecular ions of the labeled and unlabeled TCDD end the C0C1 lose for the unlabeled TCDD. Am e point of reference, the chrometogrephle trees for the 2,3,7,l-TCDD is givam la Figure 2 showing comparable ions. The quantitation for the 1,3,1,1-TCOO is based on'the celibretion curve generated for this 2,3,7,l-TCDD end may 1m subject to some degree of error. 4 HONS 220*06 TABLE 3.

An additional connant should also be mads about ths spiking experiments. In sampls 9A9 an interference peak limited ths dstsetion limit to 3.S ppt. When 1.9 ppt of 2.3.7.B-TCDD was spiked into a replicate sampls ths peak grew to 4.B ppt for a difference of 1.3 ppt which is reasonable in view of the uncer tainty in these analyses at these levels. For sample AlS the 5 ppt detection limit was determined by the ultimate sensitivity of the GC/HS and there were no interferences in the second workup of this sample. Therefore the 19 ppt spike should be compared directly to the 13 ppt supl* recovered. Again this result is rtastmBirl s in light of the difficulties encountered in analysing this particular sample.
