The North Dakota Environmental Health Association (NDEHA) was founded in 1942 as the North Dakota Association of Milk Sanitarians. In 1952, the Association became the North Dakota Association of Sanitarians. In 1970, the National Association changed its name to the National Environmental Health Association and the State Association followed suit to become the North Dakota Environmental Health Association. NDEHA is incorporated under the laws of North Dakota as a nonprofit professional association. Active membership is open to anyone who works in environmental health, public health, or a related activity.
