On Wednesday, we went around all the rivers and streams in the Kaituna catchment to test the water for flow rate, pH levels, Dissolved oxygen (DO), and temperature. We took samples in little bottles to send to the laboratory in Whakatane where they test for chemicals and bacteria. Some of the streams and rivers we tested are right here in Te Puke. You might know some of them... The Raparapahoe and Ohineangaanaga streams? We even went up Manoeka Road to test the Kirikiri stream.
Just the Facts: Dissolved Oxygen (DO) is the amount of oxygen that is present in the water. It is measured in milligrams per liter (mg/L), or the number of milligrams of oxygen dissolved in a litre of water. Good DO levels are important for creatures who live in the water as they need oxygen for their survival.
