Sanitary landfills are designed to dispose of waste in a safe and environmentally friendly manner, but they can still have negative impacts on water quality if they are not properly managed.
Landfills can leak contaminants into the soil and groundwater, which can then reach the Yangtze river. These contaminants can include heavy metals, organic compounds, and bacteria, which can all harm aquatic life and human health.
In addition, landfills can also generate methane gas, a potent greenhouse gas that can contribute to climate change. Climate change can lead to changes in the Yangtze river's flow, temperature, and water quality, which can all have negative impacts on the river's ecosystem.
