We recently received an email from 'LeeAnne' who asked, "I need to know if any of your home water testing kits test for trihalomethanes. Please email me or call. Thanks."
Although we wish a kit like that existed, at this time we do not know of an at-home water test kit that detects trihalomethanes. All of the detection methods we know about must take place in a laboratory setting using equipment that costs, well, a WHOLE lot more than an arm and a leg.
We do, however, know of several mail-in water test kits from National Testing Laboratories that detect trihalomethanes and host of other common drinking water contaminants and water quality characteristics. Each kit comes with sample collection equipment, instructions on how best to collect your sample, and items necessary for the safe shipping of your sample to a National Testing Laboratories certified water testing facility.
What ARE trihalomethanes?
When drinking water sources get processed and made potable, some of the processes involved may use free chlorine as the disinfectant. When chlorine molecules interact with biological contaminants in the water a class of compounds known as disinfection byproducts get created in small quantities.
Scientists and health experts currently believe that exposure to elevated levels of disinfection byproducts in drinking water over time increases a person's risk of developing certain types of cancer.
Trihalomethanes are classified as disinfection byproducts.
