If all got is a yard and no proper liquid-transfer device around - go ahead and neutralize the OA (It stops fizzing as you hit the "Fully-Neutralized State). If you have done this much so far - and truly have no other method - pour it slowly on the ground next to/into a hole you dug already. As it transfers in the into the acid-hole - wait until done and rinse it twice (the kiddie-pool) with clean tap-water. Place a garden-hose upstream to the hole and let a small trickle of water come to the top of the hole you dug. Flip the kiddie-pool over and put your name on it. Place this over the active OA and top with a brick or similar.

Allow to soak and disappear all such with this method. The next day - hose the area down with lots of water. As is said with poisons 101 - Dilute! Dilute! Dilute!. Do this several times over the day. Then certainly overhaul etc. Colour v. Color next next time will be obvious - you can in a talk with. This makes El Presidente good to go again.
