After finishing "Amazing Aqua Cura" quest with ending "Forcing Griffon to confess", and going to Underworld months after these events, you will still see intacted podium, table, crates and etc.
So, I made this little mod for myself, but maybe someone will also find it useful. 

WHAT TO EXPECT (I really suggest to open "Images" section of this page)
.....................................................................................................................................

1) Removed all signs of Aqua Cura near Museum of History Entrance;

2) Moved all Griffon's equipment and crates to simulate Ghouls attempts to hide his junk behind the mammoth statue;

3) Put graffiti on main sign of Aqua Cura near water barrels;

4) Removed Griffon's podium;

5) Removed all bottles of Aqua Cura from this location;

HOW TO INSTALL
.....................................................................................................................................
There are no scripts, it's all done manually, so you should activate this mod only AFTER FINISHING "Amazing Aqua Cura" quest with "confession ending".

1) Put .esp file in Data folder or use Vortex Download option;
2) Activate in any mod manager;

BUGS AND CONFLICTS
.....................................................................................................................................
Should be compatible with any other modifications
