Technically, it's only trapped for good if the terrain at bottom of the water cannot be removed to allow the particle to drop further down. So it would be somewhat of a behavior change if the particle respawns based on being in water (either as soon as it hits water, or as soon as it stops dropping but is still inside water), though probably no levels are depending on the current behavior, so it's probably a good change. There are also other hazards to consider as well in general, making it likely that the game might not always be able to cover all such situations. Thus it might be worthwhile to also consider an "admin failsafe" option where the admin can explicit issue a command during the match to reset all dropped particles.
[edit: I guess another solution would be to add a new type of object that can eat dropped particles, and then together with the respawn option, it would solve the problem w/o admin intervention, in cases where it's too tricky otherwise for the game to try to detect the need to respawn]
As a temporary workaround, if you can't simply have the water be at the bottom of the level and make use of the respawn option, you might still be able to fix the current situation by making the bottom of your pool of water be a "bridge" contraption (those floors that can automatically set to open and close on regular intervals), instead of regular terrain that may not be destroyed. Then the particle will eventually fall off the bridge and out of the water the next time the bridge opens itself. It may be a little sketchy aesthetically but should be a workable solution for now, and you can further try to cover up the aesthetics by overlaying some background image over the bridge so the players don't see the actual bridge object.
