Final answer:
Health concerns from fracking noise pollution stem from potential contamination of water supplies with carcinogenic chemicals and other hazardous materials, which can lead to significant public health issues.
Step-by-step explanation:
One health concern related to noise pollution from long-term fracking is the potential for contaminated water and the associated risks from hazardous constituents such as heavy metals, radioactive materials, and volatile organic compounds (VOCs). These contaminants, which may include carcinogenic chemicals like benzene, toluene, ethylbenzene, and xylene, pose serious risks if they enter the water cycle and potentially affect groundwater resources. Despite industry reassurances, the contamination could occur due to human error or system failures, leading to substantial public health implications from chronic exposure to these substances.
