If you think all that water disappears, think again. Runoff eventually ends up in the ocean, which is why the sea tastes like salty regret. But before it gets there, it often passes through groundwater—the secret underground reservoir. Some runoff infiltrates, sneaking down to refill the aquifers we all drink from. It’s a stealth mission, not a party.
So the next time you see a puddle racing down the street, tip your hat. That tiny rap sheet of water is a thief, a builder, and a demolition expert. It carved the Grand Canyon (give or take a few billion years), and it’s currently plotting its next move in your backyard.
Runoff: water’s most entertaining, slightly dangerous, and utterly necessary troublemaker. Don’t let it ruin your picnic, but do let it remind you that the water cycle is never, ever boring.
