Yep. They might dump enough bentonite in it to plug it up, but the water will find it's way back out again. It's just a question of how long.
Nature happens :)

My thoughts too. It might be broke worse than they can afford to fix.
Works pretty good...
Florida sinks tend to spread pretty wide due to the crumbly nature of the limestone down here [lots of coral nodules and voids], the sandy soils on top, and high water tables. Missouri karst tends to be much more uniform, stable and solid, so holes usually rather limited in diameter. Missouri topsoils are often clay with moderate sand content and in some areas, are composed ofa layer of loess which is interesting stuff as it claylike and made of flakes rather than round particles. It's a soil which was formed of windblown particles from further west- evidently at one time there were enormous dust storms that blew this material in.
Anyway, if you tried to cut a trench through sand it would slump at an angle, say 45% slope and partly fill in the hole, but loess barely slumps at all since the flaks stay flat and level upon each other. A trench through otherwise undistrubed loess stays neat and vertical, even when it rains, though the top surface if exposed would be slick as snot on a doorknob. That's probably why Florida sinkholes over comparable voids seem to spread so far while Missouri sinks are more narrow.
