Are There Regulatory Guidelines for Trihalomethanes?
Yes, there are regulatory guidelines to control the levels of THMs in drinking water. The United States Environmental Protection Agency (EPA) has set a Maximum Contaminant Level (MCL) of 80 micrograms per liter (µg/L) for total THMs. Similar guidelines exist in other countries to ensure that drinking water is safe and to minimize the risk of exposure to potentially harmful levels of THMs.
