Pembroke pollution

 The 21 I was thinking of using my pressure washer to remove complete coverage of moss
Today completely clean

 My fountain into the fish pond fed by water off the roof nothing living completely clean

The long established grey lichen is  dead wood completely clean

IF IT DOES THIS TO LICHENS WHAT DOES IT DO TO US 

MASS POISONING

Pembroke Pollution 220217

 Last night heavy rainfall  all wooden surfaces grey covered in lichens  washed clean and bleached

Last time it happened was when Pembroke power Station came on stream it took months for the lichens to recover. Whatever they used to flush their systems was done at night and then totaly denied
