Daily Treated Wastewater Quality at Eastern Treatment Plant

Encompassing selected discharge quality data from the Eastern Treatment Plant (ETP) in Melbourne, Australia. Samples are taken as grab samples at specific timestamps, with results reported in milligrams per liter for parameters including Ammonia, BOD, COD, and Nitrogen.

Use Cases

• Analyze trends in Ammonia (Ammonia as N) concentrations over time to monitor treatment plant performance.
• Model the relationship between Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) to assess organic pollutant removal efficiency.
• Assess compliance with discharge limits by comparing Nitrate plus Nitrite and total Nitrogen levels against regulatory benchmarks.
• Investigate correlations between different quality parameters like BOD and total Nitrogen to understand treatment process dynamics.

Strengths

• Data is provided by the Melbourne Water Corporation, the authoritative water utility for the region.
• Includes multiple key water quality parameters such as Ammonia, BOD, COD, and Nitrogen.
• Available in multiple machine-readable formats including CSV, XLSX, and GeoJSON.

Limitations

• The data provider explicitly states it makes no guarantees as to the accuracy or completeness of the data, placing validation responsibility on the user.
• The sample data and specific column structure are unavailable, limiting pre-download assessment of data granularity.
• The dataset's temporal coverage and total record count are unknown.
