These are some of the organisations
that monitor Rapid Creek's water
quality:

- What is Water Quality?
-
Water quality is how healthy the water is. You can
tell the water quality by the amount of macro-invertebrates. If
there are a lot of bugs that means that the water has a lot of
nutrients and is good for the environment.
Some of the things that
affect Rapid Creek water are as follows:
Plant
Communities: Plant communities help the creek to get all of the
nutrients that it needs and provides energy for the animals that live off
the creek, they also help with erosion.
Pollution:
Pollution affects the creek in a lot of bad ways. It can be raw sewerage,
litter and oil leaks etc. Pollution can be lethal to all of the
wildlife.
Introduced species: One of the introduced species
is weeds. They can suffocate our native plants and that causes the animals
that live off it to die. Another introduced species is Cane
Toads. They were brought to Australia to get rid of the Cane Beetles, but
they ate everything except Cane
Beetles.
- Our Excursion
-
When our class went down to Rapid Creek we
met from Greening Australia Jane Ellem and did the PH level test, oxygen
test and the macro-invertebrates count. When we did the PH level test it
was a 5 on the scale which is very good for humans and animals such as
bugs. When we did the macro-invertebrates count we found some interesting
insects that are fairly sensitive which is a really good
sign.
