    Abstract: Differential UV absorbance (.DELTA.A) has been successfully used as a surrogate for the formation of DBPs in chlorinated water. .DELTA.A analysis has the advantages of being fast, easy, and amenable to in-situ applications. In this research, .DELTA.A/sub 272/ was explored as a TOXFP(formation potential) surrogate for NOM samples collected from five sources using various concentration and separation techniques. Effects of concentration techniques and separation methods on TOX-.DELTA.A/sub 272/ correlation were discussed. A summary of the results from this study is as follows:.DELTA.A/ sub 272/ is better TOXFP surrogate than A/sub 254/ and SUVA/sub 254/. Concentration techniques do not strongly affect the TOX-.DELTA.A/sub 272/ relationship. Hydrophobic and hydrophilic neutral fractions have high k values but they do not account for a significant amount of NOM. The high k values might be attributed to the high contents of proteins and amino acid structure in these samples.
