A supported capillary membrane sampler-gas chromatographic method for monitoring trihalomethanes in drinking water
The major problem with water chlorination is the formation of trihalomethanes (THM's) as by-products of the disinfection process. The concern over THMs as disinfection by-products arose because of their possible carcinogenicity. The USEPA originally set the maximum contaminant level (MCL) at 0.1 mg/L. More recently, the disinfectant / disinfection by-product rule lowered the MCL1 for THM's to 0.080 mg/L in finished water. Stage two will further lower the MCL to 0.040 mg/L by 2003. Because of this, many water utilities are interested in new and improved methods for monitoring THM's in finished water.
