In the water cycle of mother earth, she nourishes us with her hydrospiritual presence. Rainfall becomes streamflow that becomes aquifer which you drink. A perfect cycle that Bush completely destroyed and now Obama will have to fix it!
Water shed off a field or pasture may have dirt and weed seeds floating in it, but this is easily cleaned by sedimentation, allowing the water to sit and the sediment fall to the bottom of a pond.
Water shed off of city streets takes more to clean, i.e. make drinkable. All the oils from cars and trucks as well as dog droppings, dead birds, the ooz from trash containers are all washed into the water supply and have to be cleaned before we can use it.
A field may have a lot of dirt, but it is easier to make clean drinkable water from, were a city area will have to deal with heavy metals, oils and other chemicals that need to be clean out of it as well as bacteria.
