Question

why is using mississippi river water for drinking water sometimes a problem for new orleans? because the river runs dry many times, especially in the summer because it is heavily contaminated by human activities upstream because its too far away from the city and has to be hauled in

Explanation:

• The first option is incorrect as the Mississippi River does not frequently run dry, especially not in a way that would regularly disrupt New Orleans' drinking water supply.
• The third option is incorrect because New Orleans is located along the Mississippi River, so the water does not need to be hauled in from a great distance.
• The second option is correct because upstream human activities (like industrial waste, agricultural runoff, sewage) can contaminate the Mississippi River water, making it a problem for use as drinking water in New Orleans.

Answer:

B. because it is heavily contaminated by human activities upstream
