Only 5% of water on fire serves to extinguish, remainder runs off contaminants

“…NIST, the largest fire research labratory in the world informs the fire service that only 5% to 10% of the water applied to a fire contributes to extinguishment. The remaining 90% to 95% is run off that contaminates ground water that leads to storm sewers that contaminate rivers, lakes and streams impacting aquatic life. NIST also informs the fire service that adding just 1% Class A foam concentrate (zero added PFAS and enviromentally safe) to 99% water, improves the efficiency of water by 300% to 500% which extinguishes fire faster reducing the contaminant load that harms the public, Chief Hughes Battalion 1 (rtetired) Chicago FD” — from a comment on https://www.youtube.com/watch?v=iUnpOFpEzx8
