Telling my friend about DOC #surfactant in creek. He was worried at first sight but it's not pollution. It is a #natural occurrence. It's an essential part of a healthy & functioning #forest #ecosystem.

Naturally occurring stream foam can be off-white, light tan, or brown. Formed by dissolved organic matter/dissolved #organic carbon (DOC). DOC results from the breakdown of organic debris, tannins & #watershed soils rich in organic materials.
