Ground Pollution: Understanding The Root Causes

Ground pollution, also known as land or soil pollution, is caused by a variety of human activities. These include industrial activity, agricultural chemicals, littering, construction, mining, extraction, and the improper disposal of waste products. Soil contamination occurs when xenobiotic chemicals, or human-made chemicals, spill or leak into the ground. This can happen through accidental spills, such as oil and petroleum leaks, or the corrosion of underground storage tanks and piping. Landfills, if not properly managed, can also cause ground pollution as harmful substances can leach into the soil.

Industrial activity

The effects of industrial activity on ground pollution are far-reaching. Soil pollution, caused by industrial activity, can threaten public health and food security. It can also lead to the extinction of species and increased health and environmental impacts. The Global Land Outlook (GLO2), published in 2022 by the United Nations Convention to Combat Desertification, warns that pollution is the biggest environmental cause of disease and death in the world today, with soil pollution being a major contributor.

Furthermore, industrial activity often involves the use of hazardous materials and the production of solid and liquid waste. If these materials are not properly managed and disposed of, they can contaminate the soil and groundwater. This can occur through the dumping of solid waste in landfills, which can lead to the production of leachate, a liquid that can contain toxic substances. If not adequately contained, leachate can seep into the soil and pollute groundwater sources.

To mitigate the impacts of industrial activity on ground pollution, proper waste management and disposal practices are essential. This includes the proper containment and treatment of hazardous materials and waste products to prevent their release into the environment. Additionally, the use of sustainable and environmentally friendly practices in industrial settings can help reduce the impact on the ground and the environment as a whole.

Agricultural chemicals

Soil contamination from agricultural chemicals can have severe effects on vegetation and wildlife in the area. It can also impact human health, as warned by the Global Land Outlook (GLO2) report published in 2022 by the United Nations Convention to Combat Desertification. The report highlights that pollution, including soil pollution, is the biggest environmental cause of disease and death worldwide.

Another example of agricultural chemical pollution is the use of herbicides. These chemicals are designed to kill unwanted plants and are often sprayed onto crops. However, if not used properly, herbicides can contaminate the soil and harm beneficial organisms, such as earthworms and beneficial bacteria. This can disrupt the natural balance of the ecosystem and impact the health of the soil.

To prevent ground pollution from agricultural chemicals, proper management and disposal of these substances are crucial. This includes following best practices for using pesticides, fertilisers, and herbicides and ensuring that any waste generated from agricultural activities is disposed of correctly and safely. Additionally, the development and use of more sustainable and environmentally friendly agricultural practices can help reduce the impact of chemical pollution on the ground.

Improper waste disposal

Soil and land pollution are often caused by improper waste disposal. This includes the dumping of solid waste and hazardous materials in landfills, which can contaminate the soil and groundwater. If landfills are not properly managed, harmful substances can leach into the soil. For example, when organic waste decomposes in landfills via anaerobic decomposition, it produces leachate (a liquid that can contain toxic substances), methane (CH4), and carbon dioxide (CO2). If not adequately contained, leachate can seep into the soil and pollute groundwater sources. Landfills can also release methane gas, a potent greenhouse gas that contributes to climate change.

The improper disposal of waste products can also lead to increased health and environmental impacts. Soil pollution is mostly caused by chemical substances produced by human activity, and it is the biggest environmental cause of disease and death in the world today, according to the Global Land Outlook (GLO2) report published in 2022 by the United Nations Convention to Combat Desertification. The report also highlights that pollution jeopardises health and food security, threatening the well-being of half the world's population.

To prevent soil and land pollution caused by improper waste disposal, it is important to properly manage landfills and other waste disposal sites. This includes ensuring that hazardous materials are disposed of correctly and that organic waste is decomposed in a way that does not produce toxic substances. It is also important to reduce littering and to properly dispose of waste products, such as cigarette butts and food wrappers. By taking these steps, we can help to reduce the impact of improper waste disposal on the environment and public health.

Mining

In addition, mining often requires the use of large amounts of water for processing and cooling, which can become contaminated with chemicals and heavy metals. If this contaminated water is not properly treated and contained, it can seep into the ground and pollute groundwater sources.

The impact of mining on ground pollution can be long-lasting and difficult to remediate. Even after mining operations have ceased, the residual chemicals and waste materials can continue to leach into the surrounding environment, causing ongoing pollution and contamination.

To mitigate the impact of mining on ground pollution, proper waste management and containment practices are essential. This includes the use of lined and covered landfills, wastewater treatment, and the implementation of strict environmental regulations to ensure that mining operations are conducted in a responsible and sustainable manner.

Acid rain

Industrial processes, such as mining, often release toxic chemicals like arsenic, sulfuric acid, and mercury into the environment. These chemicals can contaminate the soil and water, making them unsafe for human and wildlife habitation. Acid rain can also corrode buildings and infrastructure, leading to further environmental degradation.

Agricultural practices, including the use of chemical fertilisers and pesticides, contribute to acid rain formation. When these chemicals are washed off fields and into water bodies, they can increase the acidity of the water, harming aquatic life and disrupting ecosystems.

Improper waste disposal, such as dumping solid waste and hazardous materials in landfills, is another significant contributor to acid rain. Landfills that are not properly managed can allow harmful substances to leach into the soil and contaminate groundwater sources. The decomposition of organic waste in landfills produces toxic substances, methane, and carbon dioxide. If not adequately contained, these pollutants can seep into the soil and further contribute to acid rain formation.

To mitigate the effects of acid rain and reduce ground pollution, it is essential to address the root causes. This includes implementing better waste management practices, reducing industrial emissions, and promoting sustainable agricultural methods. By taking proactive measures, we can help protect the environment, preserve public health, and ensure a more sustainable future for generations to come.
