IR SPECTRA. The IR spectra of all 10 samples derived from drinking water are almost identical. Figure 1 shows a representative spectrum. For comparison, the IR spectra of Satilla River aquatic humus and CFH are added. All samples exhibited broad bands in the 3400-cm 1 (—OH), 1720-cm"1 (C=0), and 1640-cm 1 (C=C) regions. However, the spectra from the 10 drinking water samples and CFH samples showed distinct differences from that of the Satilla River aquatic humus, which absorbs sharply near 1600 cm-1. This result suggests that the samples derived from drinking water are strongly altered by chlorination and/or oxidation. Further confirmation of the spectral dissimilarities should be pursued by analysis of chlorinated alteration products of humus.
