What is non-point source pollution, and why is this kind of pollution hard to monitor and control? from what source do most americans get their water for everyday use? what three things can we do to conserve this resource? an aquifer has been compared to a sponge. think about this analogy for a moment and explain why the use of the word "sponge" is more appropriate than the use of "underground river" to describe aquifers.

The use of pesticides in farming land is example of non-point source pollution. The area of emitting of pollution is very large. That is why, it is difficult to monitor and control this type of pollution.

Americans get their water for everyday use through aquifer. Aquifers can be conserve by avoiding high amount of chemical uses and reducing household waste. Also the sustainable use of water cause conservation of natural resource.

Aquifer are basically underground water present in ground pores. The structure of aquifer just look like sponge. The water moves through the porous surfaces of the ground.

pretty sure it's false
