Did EPA examine inhalation and dermal studies in developing the drinking water health goal for chloramine?
Yes. In 1994, EPA examined inhalation and dermal studies on chloramine when determining the health goal (the Maximum Residual Disinfectant Level Goal or MRDLG), but there was not much information available. These studies covered both human clinical cases and animal studies and are summarized in the criteria document for chloramine. EPA is in the process of conducting a new literature search, and if additional information is found, the Agency would expect to update the criteria document. EPA based its health goal on the lowest effect dose seen (or the lowest intake of chloramine to show any adverse effects) among all studies examined and made further adjustments from the low dose to allow for an adequate margin of safety. In the case of chloramine, this was a drinking water study in rats. See the Stage 1 Rule for further information. I am experiencing respiratory, skin, or digestive problems. Could it be chloramine in the water? The available studies do not link these conditions to chlo
