Maybe the subsidence issue being addressed now means there is to be a new inspection of the 'Puddle' soon!
With regard to the leak how on earth could the correct temperature, chemical balance, contamination etc. of the water be monitored if it has to be continually filled up?
If anything does happen security wise at the 'Puddle' do you think the Russian or the local gendarme will rush around there and what could a lad in a vest t-shirt with a mobile phone actually do to stop drunken people going for a dip!
