Monitoring Sites - pH

Abstract Monitoring sites where pH data, defined as 'pH of surface water collected above the tidal limit of a watercourse' (subcategory 9g of the [Water Regulations 2008]), is collected, stored and provided to the Bureau of Meteorology by data owner organisations. The sites represent the current offering on the Bureau of Meteorology's [Water Data Online website]. Sites presented on the Water Data Online website have gone through a series of high-level quality checks. This data is subject to their terms and conditions of use. Please refer to Copyright on the Water Data Online website, and Disclaimer statements relating to the use of Bureau of Meteorology material. Currency Date modified: 20 May 2026 Modification frequency: Quarterly, new sites introduced to Water Data Online after the last update will appear in the next update. Data extent Coordinate Reference: Geocentric Datum of Australia 1994 (GDA94) Spatial extent North: -9° South: -55° East: 170° West: 70° Source information Data has been delivered to Digital Atlas Australia, in CSV format, by the Bureau of Meteorology on 14th May 2026. Lineage statement The Bureau of Meteorology is the custodian of water data provided by external organisations under the Water Regulations 2008. The organisations from which the data originates are known as ‘data owners’. The Bureau stores most data received under the Water Regulations 2008 in the Australian Water Resource Information System (AWRIS). The Bureau receives pH time-series data for each of the monitoring sites presented in this dataset. Some high-level quality checks have been performed on the data to warrant their suitability to publish them on the Bureau's Water Data Online website. The monitoring points presented in this dataset only reflect those that are published on Water Data Online. The monitoring sites all have a URL link to the Water Data Online station page, where the time-series data for the specific site is available to inspect and download. It will also include the information/data for other variables measured at the site as well as a number of summary and specialist reports giving specific information about the data. All time-series data presented on Water Data Online can be accessed via the Bureau's SOS2 web services (API). SOS2 web services for Water Data Online can be accessed via the [GetCapabilities request for BOM Water Data Services]. Further information can be found in the FAQ tab of [Water Data Online] (last item). For this dataset, the Digital Atlas of Australia team at Geoscience Australia has made minor amendments and the addition of cartographic symbology to support conversion into a hosted feature service. Additionally, labels and popups were added to improve accessibility and enhance ease of use.
