Did you know that foaming on the surface of lakes and streams is often a naturally occurring phenomenon and not a result of environmental pollution?
đź’§ Foam formation is common in water with high organic content, such as productive lakes and darker-coloured streams originating from wetlands or woody areas.
đź’§ Aquatic plants naturally die and decompose in lakes, releasing organic material such as oils which float to the surface. Wind and wave action push the oils along the shoreline where turbulence introduces air into the organically enriched water forming bubbles.
đź’§ Slimy foam in water may be caused by pollution especially if near a potential pollution site or if its formation does not align with wind or turbulence direction.
