This paper developed methodology to assist school principals in determining the existence of potential indoor air pollution problems and how to alleviate them, as well as a procedure for pollution prevention. Site visits were conducted on 10 South Carolina elementary schools: five with high potential for indoor air pollution; five with low potential. Site visits revealed the principals of all 10 schools had little knowledge about indoor air pollution problems, and little understanding of the operation and maintenance of their buildings and support systems. Study findings suggest that only when principals become aware of the causes of air pollution, the problems it can create, and its prevention, should they get involved in the diagnostic, alleviation or prevention activities. The study isolates climate control and ventilation as two primary areas of concern which need to be addressed to avoid wasting time and resources. Proper maintenance was found to be the best preventive activity for indoor air pollution problems, and the one most often cut during budgetary restrictions. Appendices provide the survey form used in the study, copies of correspondence, and the manual entitled, "The Diagnosis, Alleviation, and Prevention of Indoor Air Pollution in School Buildings: A Manual for School Administrators."
