Sunwater monitors the water quality of storages (dams and weirs) in line with regulatory requirements and the Department of Natural Resources, Mines and Energy Water Monitoring Data Collection Standard. We monitor water quality within the storage, including blue-green algae levels, and in the downstream river. The frequency of monitoring varies according to the Standard’s requirements.
The water quality data consists of two main types:
Field measurements — by Sunwater staff on site with a monitoring device
Laboratory measurements — in a laboratory on water samples taken by Sunwater at the site.
The following data is collected and supplied as raw data:
Amount of oxygen dissolved in the water
Acidity or alkalinity of the water
An indicative measure of salts in the water
Amount of all nitrogen in water, including ammonia, nitrates, etc.
Amount of all forms of phosphorus in water
Amount of sulphides in water including hydrogen sulphide (rotten egg smell)
Tips on using this raw data
The data can be viewed to check the most recent water quality measurements. If required, this data can be manipulated using your chosen spreadsheet software (e.g. Excel) and can be filtered or used to create graphs. Refer to the help function in your software for more details if required.
