The Times: Alert at Lake Windermere over toxin levels that turned water green
"Four fifths of the shoreline around Lake Windermere falls short of quality standards, with a majority of water samples showing raised levels of pollutants, a survey has found.
Local campaigners raised concerns over the state of England’s largest natural lake last summer, when it turned green due to an algal bloom driven by phosphorus and nitrogen.
Now the largest survey of its condition, with water samples taken from almost 100 sites, has found widespread pollution."
