The use of biomass energy can have both positive and negative impacts on water quality. The following are some of the ways in which the use of biomass energy can improve and decrease water quality:
Improvement:
1. Reduced dependence on fossil fuels – Biomass energy can reduce dependence on fossil fuels, which can reduce the amount of pollutants and greenhouse gases emitted into the environment. This can improve water quality by reducing the amount of contaminants that enter the water.
2. Improved land management practices – Growing and harvesting biomass crops can improve land management practices, which can lead to reduced soil erosion, better soil health, and improved water quality.
3. Reduced chemical use – Biomass energy systems can use organic fertilizers and pesticides instead of synthetic ones, which can reduce the amount of chemicals entering the waterways.
4. Water quality improvements through the use of biomass-based fertilizers – Biomass-based fertilizers, such as biochar, can improve soil water retention, which can reduce the amount of water that needs to be used for irrigation. This can increase overall water availability, and therefore benefit overall water quality.
Decrease:
1. Water usage – Biomass energy production requires a significant amount of water, which can be drawn from local water sources. This can lead to decreased water availability or degrading of water quality.
2. Runoff – Biomass crops require fertilizers and pesticides, which can lead to runoff into nearby water sources, resulting in water contamination.
3. Improper waste disposal – Biomass production results in a lot of waste, which if not properly disposed, can lead to water pollution.
4. Unforeseen contamination risks – there is always a risk of contaminating water sources when moving and handling biomass crops. For example, a hose used for transferring waste from a biomass production facility can accidentally become a source of contamination.
Explain how the use of biomass energy can both improve and decrease water quality.
