Your report should be fully referenced within the text, including any pictures or diagrams used, and include an Abstract at the beginning (no more than 8 lines). The Abstract should be followed by an Introduction, then four individual Sections (one per disinfection method). Follow these sections with a separate section that discusses when a combination of methods may be needed.
