For waterworks the most fundamental subject is to maintain the safety of drinking water. It has become important every year to monitor the concentrations of trihalomethanes (THM). We developed a new automatic THM analyzer based on fluorometry with membrane separation, and investigated a correlation between the gas Chromatographic method and our THM analyzing method on drinking waters at 10 cities in Japan. The investigation resulted in good correlation (r=0.9807) between both methods. Good results were obtained when continuous measurements of THM in drinking water were performed by the analyzer. Consequently, it was found that the present analyzer could measure THM in drinking waters simply, rapidly, with good precision and could be applied to continuous monitoring of THM.
