Laboratory experimental studies were carried out on river water, reservoir water and enriched natural organic mater (NOM) to evaluate the effect of Br^- brought about by seawater intrusion on the formation of trihalomethane (THM). The experimental results indicated that the quality of river raw water and reservoir water collected was good with a TOC of less than 2.5 mg/L and a maximum THM formation potential (THMFP) of less than 175 mg/L. However, an increase in the Br- content, or the Br^-/TOC ratio, in river water due to reasons such as seawater intrusion would significantly increase its THMFP. For these two natural water samples, Br- content had the similar effect on the THM formation after chlorination. In comparison to the pure NOM water, the organic impurities in river and reservoir waters were lower in THMFP, which were to a less degree affected by the Br^- content.
