The Indian Health Committee met in Aberdeen, South Dakota, during the week of May 23, 1977 to (1) review the environmental health services provided to the tribal units on the 15 Indian reservations located in North Dakota, South Dakota, Nebraska and Iowa, and (2) make recommendations for improvement or expansion of current programs, if needed. The Committee observed conditions on the Fort Berthold, Standing Rock, Cheyenne River, Lower Brule, Crow Creek, Winnebago, Yankton, Santee, Rosebud, and Pine Ridge Indian Reservations. Service unit facilities and staff were visited at Turtle Mountain, Eagle Butte, Winnebago, Yankton, Rosebud, Pine Ridge, and Rapid City. Observations were made on the following specific facets of the environmental health programs reviewed by the Committee: accident control, solid and liquid waste disposal, water supply, institutional environmental health, sanitations at celebrations, zoonoses control (vector and vermin), housing and premises sanitation, epidemiology, and environmental health personnel. Among the recommendations were that: the staff be expanded; closer coordination between the Indian Health Service environmental health programs and state and Federal agencies having related concerns should be given priority attention; current efforts to encourage the development of appropriate sanitary codes and regulations and effective enforcement procedures by the tribal councils be continued.
