Final answer:
The statement 'water pollution' is not directly related to hazardous waste, as it is a broader category that includes various contaminants, not all of which are classified as hazardous waste. The option (D) is correct.
Step-by-step explanation:
The statement that is not related to hazardous waste is water pollution. Hazardous waste refers to solid waste that poses potential hazards to human health or the environment when improperly treated, stored, transported, or disposed of.
It includes substances such as nuclear waste, biohazard waste, and other waste materials that create significant environmental and public health risks. Water pollution, while a significant environmental concern, is not directly related to hazardous waste as defined. Therefore, option (D) is correct.
