This paper describes a two-site reaction scheme that successfully simulates formation of chloroform and all chlorinated haloacetic acids (HAAs) from chlorination of several natural waters, treating the concentration of reactive sites in the raw water as being proportional to A254. The optimized reaction rate constants suggest that the rate limiting step in all cases is the first chlorine attachment step. The rate constants for different reactions in the sequence vary by approximately five orders of magnitude, but the rate constants for a given step vary by only approximately a factor of three among the different water sources tested. The model is currently being expanded to include disinfection byproduct formation in waters containing significant amounts of bromide. Includes 7 references, tables, figures.
