Australian Stockholm Junior Water Prize past winners
Challenge yourself at the Australian Stockholm Junior Water Prize.
An annual water science competition for high school students.
Mikayla Rodger, Meriden School
Mikayla's project involves research into the causes of toxic cyanobacteria blooms and the development of a system which mitigates the risk. Cyanobacteria blooms plague global waterways and seriously impact the health of aquatic organisms, terrestrial animals, and humans. This threat is growing in prevalence alongside climate change and thus she aimed to design a system which prevents uncontrolled cyanobacteria reproduction (a bloom event), whilst allowing natural populations to exist. The design, the SolarCyanoSlayer, is also aimed to be self-sustaining for long-term implementation and constructed of biologically derived and recycled materials, reducing the embodied energy of construction. When placed in simulated eutrophic conditions the invention was demonstrated to be highly effective in countering cyanobacteria blooms and subsequently improving overall water quality.

2020 Winner - Emma Serisier, Bishop Druitt College
Macinley Butson, The Illawarra Grammar School, New South Wales
The SODIS Sticker: Development and testing of a Film based detector system for appropriate Ultraviolet Solar Disinfection (SODIS) of Water
Macinley has developed the SODIS sticker, an innovative ultraviolet radiation sticker which accurately measures the solar UV exposure required to sanitise drinking water. This is done through a high accuracy transparent UV-sensitive film coupled with a partially UV blocking filter, which allows the SODIS sticker to measure direct UV exposure from the sun and reflected UV from other objects. At just over one cent to produce, it is also a cost-effective and safe way of purifying drinking water for developing communities
Following Macinley winning the Australian Stockholm Junior Water Prize in May 2019, she went on to take home the International Stockholm Junior Water Prize in August 2019. The Prize was presented to Macinley by HRH Crown Princess Victoria of Sweden.

Recycling Waste into Biochar: A Sustainable Wastewater Filter and Fertiliser for the Agricultural Industry
Minh Nga Nguyen, Sydney Girls High School (NSW)
Nga’s project is entitled “Recycling Waste into Biochar”, a sustainable waste water filter and fertilizer for the agricultural industry. Her project formed a model of application in which agricultural plant wastes are recycled into a multipurpose biochar charcoal, that can filter wastewater and fertilise plants. Nga found that bamboo biochar filter packs could remove 45.6% of harmful pollutants in wastewater, lowering pollutant content to meeting Australian guidelines. Her findings have the potential for application in the agricultural industry, allowing farmers to recover polluting plant wastes and turn it into biochar used to treat livestock wastewater, as well as aid crop growth.

Macinley Butson, The Illawarra Grammar School, New South Wales
Macinley’s project involved the design and testing of a simple and affordable mechanical device to help solve the problems of clean water and power for people in developing communities. The Solar System, which produces solar energy, provides a supply of clean potable water for personal use as well as a sterile water supply for medical use. Macinley’s invention has the potential to help many people around the world as it can increase green energy power generation by over 70% per day and supply clean water daily.
The Australian Stockholm Junior Water Prize was awarded at Ozwater’17 in Sydney. Watch the video below and hear what Macinley said about winning the award:
In our second video Macinley shares with us her Australian Stockholm Junior Water Prize experience:
Mohamed Jakaria, Queensland Academies Health Science Campus, Southport, Queensland
Mohamed’s investigation examined the efficiency of Elodea canadensis in removing nitrate in effluent discharged from wastewater treatment plants. This was explored by answering the research question: What is the effect of increasing surface area of Elodea canadensis on the assimilation of nitrate in effluent discharged from Beenleigh wastewater treatment plant? This autotrophic aquatic plant’s ability to use inorganic nitrogen for growth provides an ecologically friendly solution to the tertiary treatment of wastewater.
The Australian Stockholm Junior Water Prize was awarded at Ozwater’16 in Melbourne. Watch the video below and hear what Mohamed said at the awards ceremony:
