Abstract Oxygen in the air transfer to wastewater in oxidation ponds through many ways and the vertical water circulation is the one of them which are needed thermal stratification of water for process flow. Therefore this research designed to set three sampling sites (points A, B and C) at midpoint transect of oxidation pond, they were perpendicular to the influent current of wastewater input from inlet for measuring indicators that have relation with vertical water circulation i.e. temperature, DO, pH, TDS, EC and salinity in each depth. By using indicators together with statistical analysis, the result found the middle sampling site (point B) as the most appropriate to be more intensively monitored. The point B was used to collect and to analyze the samples for evaluated dissolved oxygen (DO) stratification of wastewater in an oxidation pond and its showed 3 zone of DO stratification that are the top zone at surface to 60 cm depth as almost DO at here, the middle zone at 60-150 cm depth as DO decrease slowly but belong to balance, and the bottom zone a more 150 cm depth as DO dwindle to get zero and also identified as anaerobe zone.
