Sanitation in school toilets is often considered peripheral to the academic project, yet has a significant impact on productivity and the school experience. A micro-study, pilot project to quantify the perception of odours in toilets at two schools in Gauteng Province, South Africa, using olfactory tests, reveals the presence of select odour-forming compounds. The compounds of butyric acid, indole, p-cresol and dimethyl trisulfide, reconstituted faecal odour and stale urine odour were presented to staff at the two schools in the form of ‘Sniffin’ Sticks’. All the odours were identified in the toilets at levels of unbearable in School A which has a septic tank system, and tolerable in School B which uses a flush system, during the pre-test. A post-test was conducted after an effective bioremediation treatment product was applied. We found that 100% of the participants noted a marked improvement in the odours in the toilets after the treatments were combined with efficient cleaning regimes.
