PCB wastes are disposed of through which type of facility?

• A. By burning in unregulated sites.
• B. Through accredited hazardous waste facilities.
• C. In regular landfills.
• D. By dumping into water.

Answer: (B)

Handling PCB wastes must be done through licensed hazardous waste facilities because PCBs are highly toxic and very persistent in the environment. Accredited facilities are authorized to receive, store, treat, and dispose of this kind of waste under strict controls. They have the right containment, track-and-trace systems, and treatment processes (such as destruction at high temperatures or other approved methods) to destroy or stabilize PCBs and prevent releases to air, soil, or water. This regulatory oversight also ensures emissions and waste streams are monitored and kept within safety limits.

Other options fail to meet those safeguards: burning PCBs at unregulated sites can release toxic PCBs and other pollutants; disposing in regular landfills risks leachate and long-term contamination; dumping into water directly contaminates ecosystems and violates environmental laws.
