Explanation:
Water dissolves nonpolar covalent substances.
PCB (Poly-Chlorinated Biphenyls) are the major contaminants of groundwater that must be removed before circulating water among people. PCBs can also enter the food chain by contaminating aquatic organisms. Working on PCBs and removing it from water is a challenging process. Various processes are involved in removal of these contaminants from the groundwater. Among these one is the use of microorganisms. Microbial process is a potent bioremediating method.
DEGRADATION OF PCBs through microorganisms is an effective process as PCBs are susceptible to degradation. PCBs are transformed into smaller parts by microorganisms that make them more soluble and easily degradable.
Pretty sure it’s all of the above
