In this cross-sectional pilot study, the first carried out in response to the UNEP recommendations, we observed statistically significant associations between exposure to petroleum-contaminated drinking water and self-reported symptoms consistent with exposure to petroleum hydrocarbons. These results reinforce UNEP’s recommendations for establishment of a health registry, medical surveillance, and a prospective cohort study for the Ogale community [3]. Future studies should define the full extent of contaminated household water and incorporate more detailed methods of exposure and outcome assessment for exposed populations, including its most susceptible members.
