Water chemistry

The indicators that are measured in the Finniss River at Winery Road are nutrients (nitrogen and phosphorus), turbidity and salinity. The concentrations of these indicators are used to classify the water chemistry as being in good, moderate or poor condition, according to the needs of aquatic ecosystem protection.

Water chemistry classification for October 2005 to March 2006

Indicator	Classification
Oxidised Nitrogen	Good
Total Nitrogen	Moderate
Soluble Phosphorus	Good
Total Phosphorus	Moderate
Turbidity	Good

These classifications are consistent with previous results. Nutrient levels can be elevated by fertilisers or animal wastes being washed off farms during storms.

Water chemistry classification for April to September 2005

Indicator	Classification
Oxidised Nitrogen	Poor
Total Nitrogen	Poor
Soluble Phosphorus	Good
Total Phosphorus	Good
Turbidity	Good

Total nitrogen levels can be elevated by fertilisers or animal wastes being washed off farms during storms or due to effluent outfalls. The elevated nitrogen results for the recent samples are consistent with previous results.
