How much of our rain makes it back into our ground water?

    Approximately 25% of rain in the US becomes groundwater. Another 25% of it goes into streams and 50% of it evaporates into the atmosphere.

    Many cities are actually attempting to improve this number by increasing impermeable surfaces (surfaces that will absorb and use the water, like soil). Green roofs are a good example of this. A lot of our rain water is wasted by just going in to storm drains. Here in Portland, we get A LOT of rain, so the city is trying to use it as effectively as possible.
