The term sanitation encompasses hygiene, on an individual level, and public health, on a communal level. Those who specialize in sanitary science are sanitary engineers. Sanitation measures seek to eliminate or reduce health hazards associated with the supply of water and milk, the collection and disposal of sewage and refuse, and the prevalence of rodents and insects. Air pollution, and improper food handling that threaten the well-being of the public are also sanitation concern.
Sanitary engineers develop methods for safely disposing of radioactive waste material at sea and on land. There are numerous state and federal laws dealing with enforcement of sanitary conditions to protect citizens' health. Some examples include inspection of slaughterhouses, care and maintenance of medical supplies, trash collection, lanfill management, and many others.
