Examined are the reactions of chlorine with humic and fulvic fractions extracted from the River Thames and tested under controlled conditions of pH and temperature. Also studied is the relationship between residual haloforms and total haloform formation from these acid fractions under conditions generally encountered in water treatment. Monitoring of chloroform production indicates that total chloroform is composed of two components: one produced by thermal decomposition of unidentified chlorinated intermediates and the other dissolved chloroform. The dominant factor influencing both the production of total chloroform and the relative proportions of these two components is pH. (2 drawings, 5 graphs, 15 references, 2 tables)
