Just a thought.

it was the brown colour that made me think it was the bio-friendly stuff. I don’t have any technical knowledge beyond being trained to use it in shipboard days, but I understand AFFF is very environmentally unfriendly when it washes off.
The smell of the bio stuff drying on your clothes in hot weather is definitely unforgettable
