In response to a request from employees, an investigation was begun into conditions at the Anclote Elementary School (SIC-8211), in New Port Richey, Florida. Chronic respiratory illness and the presence of mold in the building were two of the most frequent complaints. The windowless building was arranged in pods. The school had 806 students in kindergarten through sixth grade, and employed 69 workers. Moisture from a chronically leaking roof has long been a problem at this school, causing mold and mildew. Interviews were conducted with 24 teachers and one cafeteria worker concerning environmental symptoms. Moldy odors were noted in many of the classroom pods and the source was thought to be wall board on the interior side of the outside walls. Considerable mold growth and water damage was visible on removal of wall paper in selected areas. Relative humidity levels were at the high end of acceptable. Insufficient outside air was being provided as evidenced by the carbon-dioxide (124389) levels, exceeding 1,000 parts per million (ppm) in most areas. Air flow measurements were less than adequate. The authors conclude that the presence of mold contaminated wall board and ceiling tile is a potential source of microbial contaminants. Insufficient outside air and high relative humidity levels were found. The authors recommend that steps be taken to improve the quality of indoor air and address the environmental concerns.
