Hi Artjak - facebook is good, honest! It has been the main way that the Somerset communities have coordinated their efforts, asking for and giving help. But don't worry if you are not on it, I am very happy to act as go-between and post on behalf of anyone on this message board.
Yes, the water is quite foul. It is 'only' river water and rain flood but there is all sorts of evil stuff in it - chemical stores have been flooded, slurry pits are underwater, not to mention all the animals that didn't make it to dry land in time. It is so, so pretty; but when the water recedes it is going to be pretty horrid. Bad enough in gardens - unspeakably bad in houses. It is going to be desperately depressing for everyone whose homes have been ruined; but perhaps our flowers and plants can cheer them up a bit!
