If you don't have very many trees in your area and it rains a lot, in your area, then grass is a good thing. Why? Erosion. Without trees or grass
(plants in general), rain will slowly (sometimes quickly) erode your land and can/will create a big muddy mess. Fertilizer may be classified as
either organic or inorganic. The organic stuff usually being made from some type of manure or other dead organic matter.
Of course, grass is usually pointless in a dry area, unless you have a farm. Much water is wasted in areas that are dry because of people's need for
grass. But grass can also be a good thing a dry area. Why? Because it keeps dust from being kicked up from wind. And we all know how irritating
dust can be. You can still get windblown dust from other places, but the grass does help keep down the amount.
Sure, putting the grass in an area where there wasn't, isn't natural. But, human comfort outweighs the needs of mother nature. Anyways, mother
nature has and will always be more powerful than man. If mother nature wants change, she will have it - the earth balances itself. So, I don't
think planting grass is a problem.
Also, there are many types of grass, and depending on the type, it doesn't have to be green to be considered healthy (although most grass that people
do know, is green). Most grass in America is usually a green type, so if the grass is yellow (or any other color but green), it means that it
isn't getting what it requires. And most of the time, it is another color because of a lack of nitrogen (or water in general - but if you water it
and it still stays another color, then nitrogen). So, all you would need is a nitrogen based fertilizer (it usually only has a few other elements or
compounds) - which isn't harmful to a water supply. They have "ground water safe" fertilizers.
Anyways, a lot of ground water isn't naturally fresh to begin with. It can have many harmful elements and compounds mixed in with it naturally. And
depending on how deep your ground water level is, and the type and amount of fertilizer used, by the time it reaches ground water (if it reaches it),
it is usually quite filtered.
