Water quality monitoring is carried out to provide information on the health of aquatic ecosystems and for recreational suitability. Monitoring programs can be single studies used to examine a particular issue or can be ongoing monitoring programs used to compare or highlight trends and changes in the range of parameters being measured. For water quality and aquatic ecosystem health monitoring, physical, chemical and biological information can be collected, analysed and interpreted in order to determine such change.
