Answer 2

Answer:

Option C. It is relatively protected from contamination by human and animal waste is the incorrect statement.

Explanation:

        Contamination by humans

• Due to increasing settlements and industrialization, pollution or contamination of the groundwater with substances like nitrate and nitrogen is occurring in high-income countries.

• Whereas in low-income countries untreated wastewater from municipalities and industries is contributing to the contamination of groundwater.

       Contamination by Animal waste

• Animal waste such as excreta of livestock contains substantial amounts of nutrients, heavy metals, oxygen-depleting substances, drug residues, pathogens, antibiotics & hormones.

• When the excreta of livestock are concentrated, the associated waste produced used to go beyond the buffering capacity of the nearby ecosystem, thus polluting the groundwater and as well as surface water.
