Bench‐ and pilot‐scale investigations revealed the influence of precursor compound concentration, pH, type of disinfectant, and temperature on trihalomethane formation. Implications of the research for altering treatment procedures to reduce trihalomethane production are discussed.

The suitability of gas chromatography for the lower‐molecular‐weight volatile end of the organics spectrum, which includes synthetic organic chemicals (SOCs), can be exploited by the use of gas chromatograph/flame ionization detector organics profiles for evaluating treatment processes designed for removal of SOCs.
