The correct option is D Surface water usually has fewer nutrients than groundwater.
Groundwater is located underground in large aquifers and must be pumped out of the ground after drilling a deep well. Surface water is found in lakes, rivers, and streams, even the rain's wetland forms come under this category. Groundwater is water contained in or by a subsurface layer of soil or rocks. It is generally less contaminated than surface water because the rocks tend to act as filters to remove some contaminants.
