Regulations set by the U.S. Environmental Protection Agency are now in effect for the determination of total trihalomethanes (TTHMs) in water systems that serve populations of 75,000 or more persons. Studies at the Lawrence Experiment Station organic analysis laboratory in Lawrence, Massachusetts indicate that sample compositing reduces analysis costs by 75 percent. Current sampling practices and sample compositing are described.
