Water quality assessment
Ecological health
We collect two samples of macroinvertebrates, one from riffle
(or flowing water) habitat and one from edge (still water) habitat.
The diversity of the macroinvertebrate community is used to describe
ecological health as being in good,
moderate or poor
condition.

Water chemistry
The indicators that are measured in the Inman River 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.

The amount of nitrogen and phosphorus can be elevated by fertilisers
or animal wastes being washed off farms during storm events or
due to effluent outfalls. These classifications are consistent
with previous results.

The amount of nitrogen and phosphorus can be elevated by fertilisers

recent samples are consistent with previous results.
