Water doesn’t just fall down a hole. It has to weave through this crazy maze of particles. And that’s exactly what cleans it.
First, physical straining happens. Big stuff like dirt clumps, leaf bits, and even tiny bugs get trapped in the pores between sand and clay. It’s like passing soup through a strainer.
Then comes the chemical part. Clay and organic matter have negative charges. Many pollutants, like heavy metals and pesticides, have positive charges. The soil grabs them like a magnet grabs paperclips.
Finally, the microbes get to work. Billions of bacteria and fungi live in one teaspoon of healthy soil. These tiny creatures actually eat the harmful stuff, like oil and bacteria. They break it down into harmless elements.
