High Schoolers: Take Action To Combat Water Pollution

High school students are taking an active role in tackling water pollution, with some impressive results. From researching innovative solutions to presenting their findings at international competitions, these young people are making a real difference. They are developing methods to reduce pollution from factories, studying the impact of groundwater contamination, and even creating their own purification systems. With a focus on both the environment and human health, their work is helping to address some of the world's most pressing water challenges.

Researching how to remove turbidity from river water

High school students are increasingly taking the initiative to research and tackle water pollution, with some impressive results. One way that students can get involved is by entering competitions such as the Stockholm Junior Water Prize, which invites students from around the world to present their findings on how to solve water pollution.

For example, Valentin Maiolo and Ariana Terenzi discovered a way to use the seeds of the Moringa tree to remove turbidity, or cloudiness, from river water. Turbidity is caused by suspended particles in the water, which can include silt, clay, and other organic and inorganic matter. These particles can block light and reduce the amount of photosynthesis that can take place in the water, harming aquatic plants and algae. Turbidity can also be a sign of other pollutants in the water, which can be harmful to human health.

To remove turbidity, students could research natural materials that can be used to filter and purify water. For example, saponite pellets, which are synthesized from natural clay materials, can absorb a large quantity of pollutants. Students could also look into using aquaponics to tackle water pollution caused by harmful fertilizers. This technology uses the same water to grow plants and breed fish, providing more food while using less water than traditional agriculture.

Another approach is to focus on reducing water pollution from factories, which often use water in their production processes. Students can research and test both natural minerals and inexpensive laboratory-synthesized clays to develop methods for reducing this type of pollution. After filtration, heat or chemical disinfection can be applied to ensure that the water is drinkable.

Studying how to use aquaponics to reduce water pollution

High school students are increasingly taking the initiative to research and tackle water pollution. One way they can do this is by studying aquaponics, a system that uses the same water for growing plants and breeding fish. This method can provide eight times more food per acre using one-sixth of the water compared to traditional agriculture, helping to reduce water pollution caused by harmful fertilisers and nutrient solutions.

To study aquaponics, students can first learn about the basics of the system and the water problems it aims to address. They can then explore different learning opportunities and resources to gain a deeper understanding. For example, they could create a model aquaponics system to observe how it works and the benefits it offers.

Additionally, students can investigate natural methods of water purification. For instance, they could research the use of Moringa tree seeds to remove turbidity from river water, or the synthesis and optimisation of natural clay materials to create saponite pellets that absorb pollutants.

By studying aquaponics and exploring natural water purification methods, high school students can play an active role in reducing water pollution and its impact on the environment and human health. They can also apply their knowledge in chemistry to develop methods that reduce pollution from factories, particularly those that use water in their production processes.

Learning about groundwater and surface water

High school students can play a vital role in tackling water pollution by conducting research and implementing innovative solutions. Learning about groundwater and surface water is a crucial aspect of understanding water pollution and its impacts. Here are some ways high school students can engage with this topic:

Understanding the Relationship between Groundwater and Surface Water

Firstly, it is essential to comprehend the interconnectedness of groundwater and surface water. Groundwater refers to water found beneath the Earth's surface in aquifers, while surface water includes lakes, rivers, and streams. Recognising how these two water sources interact is fundamental to grasping the complexities of water pollution.

Investigating Groundwater Contamination

Students can explore the various ways in which groundwater becomes contaminated. For instance, they can study the impact of landfills on the water supply, considering the consequences of leaky landfills and the potential for groundwater pollution. This investigation can lead to a deeper understanding of the environmental and human health implications of groundwater contamination.

Creating Models and Demonstrations

Hands-on activities, such as creating aquifer models, can effectively illustrate the concept of groundwater and surface water interaction. Students can design experiments to demonstrate well placement and its influence on groundwater contamination. Additionally, they can relate physics concepts to hydraulic heads, which are essential in controlling groundwater flow and direction.

Studying the Impact of Pollution

Examining the effects of water pollution on the environment and human health is a critical aspect of learning about groundwater and surface water. Students can research how pollutants, such as industrial waste or agricultural runoff, impact aquatic ecosystems and the availability of clean drinking water. This knowledge will empower them to recognise the urgency of addressing water pollution and inspire them to seek solutions.

Participating in Competitions and Projects

Encouraging high school students to participate in water-related competitions, such as the Stockholm Junior Water Prize, provides a platform for them to present their research and innovative ideas. For example, students have discovered methods to remove turbidity from river water using natural seeds, demonstrating their ability to contribute to solving water pollution challenges.

In conclusion, learning about groundwater and surface water is a multifaceted endeavour that combines scientific understanding, practical experiments, and a recognition of the environmental and social implications of water pollution. By engaging with these topics, high school students can develop a comprehensive understanding of water-related issues and become agents of change in their communities.

Creating a model to demonstrate groundwater contamination

High school students are increasingly taking the initiative to tackle water pollution and other global water challenges. For example, some students have discovered a way to use the seeds of the Moringa tree to remove turbidity from river water. Others have studied how to synthesise and optimise natural clay materials to purify polluted industrial water.

• Learn the basics: Start by understanding the relationship between groundwater and surface water. This will help you grasp the concept of groundwater contamination and how it occurs.
• Create an aquifer model: Build a model aquifer to demonstrate well placement and groundwater contamination. This will help visualise how pollution can affect water sources and the potential consequences.
• Study hydraulic heads: Relate concepts from physics to hydraulic heads used in the control of groundwater flow and direction. This will give you a deeper understanding of how pollution can spread and be contained.
• Poster board demonstration: Create a poster board that depicts how groundwater becomes contaminated. Include information on the sources of pollution, such as leaky landfills, and the potential impact on the environment and human health.
• Design a landfill: Consider the effects of leaky landfills on the water supply. This will help you understand the importance of proper waste management and the potential consequences of contamination.
• Treatment and disinfection: Learn about the processes used to treat contaminated water, such as heat or chemical disinfection, to make it drinkable again. This will showcase the importance of water treatment in ensuring safe and accessible drinking water.

Investigating the impact of pollution on the environment and human health

Another approach is to focus on large-scale aquaponics, which can address water pollution caused by harmful fertilizers and nutrient solutions. By using the same water for both plant growth and fish breeding, aquaponics can significantly reduce water usage and increase food production. Mariam Mahmoud and Fabio Luca Guzzi provide an excellent example of this by studying how to synthesize and optimize natural clay materials to purify polluted industrial water. Their creation of saponite pellets, which can absorb a large quantity of pollutants, showcases the potential of this method.

Additionally, students can investigate the impact of factories on water pollution and explore ways to reduce it. This may involve testing both natural minerals and laboratory-synthesized clays, as well as considering the application of heat or chemical disinfection to create drinkable water.

High school students can also raise awareness and educate their communities about water pollution and its impact on the environment and human health. This can be achieved through the creation of models, posters, and other visual aids that demonstrate groundwater contamination and its consequences. By understanding the relationship between groundwater and surface water, students can highlight the importance of well placement and the potential risks associated with landfills and leaky water supplies.
