Rain

All the Rain that Ever was, Still is

We’ve all heard the words of wisdom using rain as a metaphor: “Into every life some rain must fall,” according to Longfellow; or, “The rain falls on the just and the unjust,” as written in the Bible, Matthew 5:45.

But whatever figurative meaning rain holds, consider this fact: all the rain that ever was, still is. The rains that fell at the Earth’s beginning are still falling from the clouds—soaking into the soil, running into rivers and oceans and evaporating back into clouds. All the rain that ever was, still is—it’s called the hydrologic cycle.

Hard Truth About Impervious Surfaces

Here’s a little science observation for you.

Look out the window the next time it rains. Spend a few minutes looking at the streets and the parking lots. Watch all the water flowing into the storm drain.

Now look at the grass. You’ll have a tough time spotting any water flowing out of there. Now you can understand the challenges facing scientists as they study the health of tidal creeks in North Carolina. The amount of stormwater runoff has a tremendous effect on water quality. 

Rain Catchers

Stormwater runoff is a major source of pollution in our streams and lakes. Those lakes are also a source of drinking water. State law requires cities and towns to cleanup the runoff, because it doesn't get treated in sewage plants - it goes right in the lakes and rivers. Durham is launching an innovative 5 year program called 'Raincatchers' in hopes of slowing down, reducing, and naturally cleaning up stormwater.
