Today our Eco Warriors took part in Estuary Monitoring as part of our Stormwater Sleuth Project. We met Monique and Dom from Tread Lightly at the Wakaaranga Creek where our school drains come out. This is where any litter going down the drain will end up.
We performed various scientific tests to monitor the creek's health and we recorded the data.
This is what we found:
Clarity - 45 - 60cm - OK
Dissolved Oxygen - 8 - 12 - OK
Nitrates - 2 - Not good
Nitrite - 0.15 - 0.3
Temperature - 22 - 23 degrees - OK
PH Level - 7 - Good
Phosphates - 1.5 high
Litter - lots of litter - 20 - 30 pieces - mostly plastic - mostly food packaging. Some paper.
Compared to last year the phosphate and nitrate levels were a concern. Sadly last night's downpour may have caused a sewerage spill.
There were lots of weeds in the creek compared to last year.
In 2024 we are going to do a big inquiry into our estuary. We'll keep monitoring our drain trap and repeat the tests we did today.
Thank you to everyone who packs a litter-free lunch. You are helping to protect the estuary and moana.
