Bacterial Abundance in a Tokyo Wastewater Plant and Tama River

Spatiotemporal analysis of bacterial communities in an anaerobic–anoxic–oxic (A2O) wastewater treatment plant in Tokyo and the receiving Tama River. The dataset includes 16S rRNA gene analysis and ion chromatography data used to monitor bacterial composition and nutrient concentrations across seasonal temperature variations. It was authored by Akifumi Nishida and last updated on 2026-04-15.

Use Cases

• Modeling the relationship between temperature and nitrification efficiency based on Nitrospira abundance data.
• Analyzing the spatial attenuation of wastewater-derived bacterial DNA in a river ecosystem.
• Studying the stability of core bacterial communities across different treatment tanks over time.

Strengths

• Data includes seasonal temperature variations, allowing for temporal analysis.
• Analysis covers both a wastewater treatment plant and its downstream river impact.
• Dataset is openly available under a CC-BY-4.0 license.

Limitations

• Dataset is small at 15.0 KB, indicating limited scope.
• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to a single site in Tokyo.
