Picture a wildfire raging across a forested mountainside. The smoke billows and the flames rise. An aircraft drops vibrant red flame retardant. It’s a dramatic, often dangerous scene. But the threat to water supplies is only just beginning.
After the smoke clears, the soil, which was once nestled beneath a canopy of trees and a spongy layer of leaves, is now exposed. Often, that soil is charred and sterile, with the heat making the ground almost water-repellent, like a freshly waxed car.
