Question

Explanation:

• Solid waste accumulation at a landfill can contaminate groundwater through leachate, but it is not a direct source of water pollution in the same sense as chemical waste discharge.
• Black smoke from a large truck and particulates from burning fossil fuels are air - pollution sources.
• Chemical waste discharged from an oil refinery directly enters water bodies (such as rivers, lakes, or the ocean) and contaminates the water, which is a clear source of water pollution.

Answer:

chemical waste discharged from an oil refinery
