Answer:
D. plant nutrients cause algal blooms
Step-by-step explanation:
Plant nutrients causing algal blooms does not lead to ground water pollution.
Ground water is water in the subsurface of the earth which occupies pore spaces and fractures within the soils and rocks.
Ground water pollution is the contamination of ground water by pollutants. When gasoline from underground seeps and transmits using pore spaces within the rock, they can get into an aquifer thereby contaminating the water there. Also, when sewage disposal units are located up slope, a pressure gradient allows sewage to move within the pore spaces thereby contaminating ground water. Industrial wastes can also contaminate wells when they are not properly discharged.
Algal bloom as a result of plant nutrients leads to eutrophication.
