A state health agency (SHA), or state department of health, is a department or agency of the state governments of the United States focused on public health. The state secretary of health is a constitutional or at times a statutory official in several states of the United States. The position is the chief executive official for the state's state health agency (or equivalent), chief administrative officer for the state's Board of Health (or equivalent), or both.
Following passage of the Safe Drinking Water Act of 1974, during the first ten years of the program the state health departments were given new and important roles under the law. Due to new grants available, they had enhanced their programs and had many more resources to oversee and help utilities come into compliance with drinking water standards, and they were able to develop other related activities like the capacity for doing risk assessments on new contaminants of concern.[1]
