You’ll see there is not currently a federal legal limit for how much chloroform can be in drinking water. EWG’s health guidelines tend to be a lot stricter than state and federal limits. This guideline of 0.4 ppb was proposed in 2018 by the California Office of Environmental Health Hazard Assessment. (Screenshot Environmental Working Group Tap Water Database)
