Pollution Challenges In City Planning: A Ground-Level View

Ground pollution is a significant concern in the game Cities: Skylines, where it can have detrimental effects on the city and its residents. Caused primarily by industrial buildings and power plants, ground pollution leads to negative outcomes such as sickness, death, abandonment, and decreased land value. While it is challenging to completely eradicate ground pollution, players can employ various strategies to minimize its impact. These include careful zoning, placing industrial areas away from residential zones, utilizing renewable energy sources, and implementing waste management solutions like the Industrial Waste Processing Facility. Additionally, the Eden Project monument can help contain ground pollution by preventing its spread to neighbouring buildings. Players can also opt for non-polluting industries, such as farming and forestry, or focus on upgrading industrial buildings, as higher-level factories tend to generate less pollution.

Ground pollution sources

Ground pollution, or soil pollution, is caused by the presence of toxic, human-made chemicals in the soil, in concentrations that pose a risk to human health and the ecosystem. Ground pollution is generated through industrial buildings, and other buildings that produce unhealthy atmospheric conditions.

Sources of Ground Pollution:

Industrial Activity

Industrial activities are a major source of ground pollution, with manufacturing and service industries generating large amounts of wastewater and other pollutants that can contaminate the soil. This includes the improper disposal of waste, leaks and spills from storage tanks, and direct discharge of industrial waste into the soil.

Agricultural Practices

Agricultural practices such as the use of pesticides, fertilizers, herbicides, and animal waste can contaminate the soil. Spillage, runoff, and improper storage of agricultural chemicals can also lead to ground pollution.

Waste Disposal

Improper disposal of waste, including private sewage disposal systems, municipal waste, and sludge spreading, can contaminate the soil. This includes waste from industrial, residential, and commercial sources.

Mining and Heavy Industries

Mining and other heavy industries can cause ground pollution through spills, leaks, and the disposal of waste.

Construction Activities

Construction activities can disturb the soil and introduce pollutants, such as lead paint and vehicle exhaust.

Radioactive Substances

Radioactive substances such as radium, thorium, and uranium can infiltrate the soil and create toxic effects.

Natural Sources

While less common, natural processes can also lead to ground pollution. For example, the accumulation of perchlorate in the soil of the Atacama Desert in Chile is attributed to natural processes in arid environments.

Removing ground pollution

Identify and Remove Pollution Sources

The first step in combating ground pollution is to identify and remove the sources of pollution. Common sources of ground pollution in Cities: Skylines include industrial buildings, factories, power plants, incinerators, and garbage dumps. By removing or relocating these pollution-causing structures away from residential and commercial areas, you can effectively reduce ground pollution levels.

Use the Eden Project Monument

The Eden Project monument is a powerful tool in the game that can contain pollution and prevent it from spreading. Place this monument near your industrial areas to keep pollution contained within those zones. The Eden Project will also increase land value across the entire map, helping your buildings reach their highest levels.

De-zone and Wait

Ground pollution in Cities: Skylines may naturally disappear over time if left alone. De-zone the polluted areas and wait patiently for the pollution to dissipate. This process can take some time, but it is an effective way to remove pollution without the use of mods.

Spread Out Your Industry

Instead of having a large, concentrated industrial area, consider spreading out your industry across smaller zones throughout your city. This dispersal of industrial buildings can help reduce the prevalence of ground pollution. Ensure you maintain adequate spacing between these zones to minimize pollution overlap.

Focus on Education and High-Tech Industry

Investing in education can indirectly help reduce ground pollution. With a higher education level, your industry is more likely to grow into high-tech sectors, which generate significantly less pollution. This strategy can be particularly effective when combined with the previous point of spreading out your industry.

Use Water Recycling Plants for Water Pollution

While this won't directly address ground pollution, it's important to tackle water pollution as well. Place water recycling plants near polluted water sources, especially after reaching a population of 16,000, to start removing water pollution. It will take some time, but your water pollution levels will decrease.

Separate Sewage and Fresh Water Systems

Ensure that your sewage pipes are downstream from your fresh water intake points. This simple adjustment will prevent polluted water from being drawn into your fresh water supply, helping to keep your water sources clean.

Use Offices as a Buffer

Consider using office zones as a buffer between residential and industrial areas. Offices seem to be less affected by pollution and can serve as a transitional zone, reducing the direct impact of pollution on residential buildings.

Plant Trees and Greenery (With Mods)

While planting trees and greenery does not inherently remove pollution in the base game, there may be mods available that introduce this feature. Look for mods that enhance the environmental impact of trees and incorporate them into your city planning to visually enhance polluted areas and potentially reduce pollution levels.

Remember, removing ground pollution takes time and patience. You may need to experiment with different strategies and combinations of the above techniques to find what works best for your particular city layout and situation.

Preventing ground pollution

Ground pollution, or land pollution, is the degradation of the Earth's land surfaces at and below the ground level. It is caused by the accumulation of solid and liquid waste materials that contaminate groundwater and soil.

Sustainable Agricultural Practices

Given that the use of pesticides and chemicals in farming and agriculture greatly contributes to land pollution, finding alternatives will help to reduce the environmental impact. Farmers can use natural ingredients by switching from bio-fertilizers to manure or enrolling in programs that provide education and resources regarding sustainable farming.

Reforestation

Reforestation involves replanting trees in areas that have experienced wildfires or tree-felling. This process helps to bind the soil, protecting it from land pollution and preventing soil erosion and flooding.

Solid Waste Treatments

When solid waste is not properly treated, it can increase the level of toxic chemicals and hazardous substances in the soil. Chemical treatment methods under a controlled environment can help reduce land pollution. This includes neutralization, which alters the pH level of waste before it gets dumped into landfills.

Reduce, Reuse, and Recycle

One of the simplest ways to reduce land pollution is to reuse or recycle items so that waste is minimized. With the growing awareness around what can be recycled and an increase in recycling carts in many cities, it has never been easier to recycle.

Composting

According to the United States Environmental Protection Agency, food scraps and yard waste currently make up more than 30% of what we throw away and could be composted instead. Minimizing and repurposing waste helps preserve the environment.

Properly Dispose of Waste

Improperly disposing of waste is a major contributor to land pollution. To prevent this, ensure that all waste is properly disposed of and that waste disposal sites are inspected regularly.

Pollution Prevention Plan

Developing a pollution prevention plan can help to identify high-risk areas and implement measures to reduce the risk of pollution. This could include regular inspections, an emergency response plan, and ensuring that land use plans and regulations protect important water supply aquifers and well fields.

Ground pollution effects

Ground pollution, also known as soil pollution, is a serious issue that can have detrimental effects on both the environment and human health. Here are some key points outlining the impacts of ground pollution:

Environmental Effects:

• Biodiversity Loss: Ground pollution can contaminate soil with toxic chemicals, heavy metals, and other harmful substances, leading to a decline in soil biodiversity. This includes essential organisms such as microorganisms, insects, and worms, which play a crucial role in maintaining soil fertility and ecosystem balance.
• Soil Degradation: Pollution compromises the quality and fertility of soil, making it less suitable for plant growth and agriculture. This degradation can take centuries to recover, and even then, it would only create a few centimetres of arable soil.
• Water Contamination: Pollutants in the ground can leach into nearby water bodies, including rivers, lakes, and groundwater. This water contamination poses risks to aquatic ecosystems and can also affect drinking water sources, creating potential health hazards for humans and other organisms.
• Air Pollution: Ground pollution and soil degradation can also contribute to air pollution. For example, deforestation, which is a form of ground pollution, releases sequestered pollutants and generates airborne dust, affecting air quality.

Human Health Effects:

• Food Contamination: Polluted soil can contaminate crops and food sources, leading to the consumption of toxic substances. This can result in various health issues, including cardiovascular disease, cancer, and other non-communicable diseases (NCDs).
• Direct Exposure: Humans can be directly exposed to ground pollution through skin contact or by inhaling contaminated dust particles, especially in urban areas such as parks and home gardens. This exposure can lead to respiratory issues and other health problems, particularly in vulnerable groups like children and the elderly.
• Waterborne Diseases: Ground pollution that leaches into water sources can cause waterborne diseases, further impacting human health.
• Population Displacement: Soil degradation and its associated effects, including reduced food security and water quality issues, can lead to population displacement. It is estimated that by 2050, soil degradation and climate change will drive between 50 and 700 million people to emigrate.
• Antimicrobial Resistance: Soil pollution can contribute to the spread of antimicrobial resistance genes, making humans more resistant to antimicrobial pharmaceuticals and compromising our ability to fight certain diseases.

Ground pollution alternatives

Ground pollution in Cities: Skylines is a negative effect on the city that can cause sickness, death, and abandonment. It is mostly generated by industry, power plants, and garbage management facilities. While ground pollution cannot be completely prevented, especially when first starting your city, there are some alternatives and strategies to minimise its impact. Here are some methods to reduce and manage ground pollution:

• Opt for cleaner and renewable energy services and facilities, such as Nuclear Power Plants, Wind Turbines, and Solar Power Plants. While these options are often costly, they produce minimal pollution.
• Implement Wastewater Treatment Plants to manage sewage and improve water quality.
• Place sewage downstream, preferably close to your border, and position Water Pumping stations upstream, away from any pollutants entering your water system.
• Upgrade your sewage facilities when possible, especially when expanding your city and unlocking downstream tiles.
• Avoid placing landfills or coal power plants near natural resource deposits. Load the map with All Unlocks to gain access to the Natural Resources Info View and identify these locations.
• Focus on education in your city. As citizens become more educated, they will practice better waste management and generate less garbage.
• Spread out your industry to reduce the concentration of ground pollution.
• Use the Eden Project monument to contain pollution within the industrial area and prevent it from spreading to nearby commercial and residential buildings.
• Keep industrial zones away from commercial and residential areas to minimise the impact on citizens' health and happiness.
• If using mods is an option, consider the "No Radioactive Desert And More!" mod to visually remove the purple ground colouration caused by ground pollution. Alternatively, the Pollution Remover mod can disable all types of pollution, including ground pollution.

While ground pollution is a challenging aspect of Cities: Skylines, implementing these alternatives and strategies can help create a greener and healthier city for your citizens.
