The More You Know

"Studies have shown that in an undeveloped area, half of the rainfall will seep into aquifers with as little as 10 percent making its way to local waterways. However, as more impervious surface is added by development, about 55% of the water will end up in local waterways, while the amount that percolates into the aquifer to replenish it is reduced to as little as 5%."
