A recent episode of the BBC Countryfile series featured iconic chalk streams, tackling pollution of water courses and the reduction of chemical fertilizers in farming amongst other things. The iconic world-class, crystal-clear chalk streams of Hampshire in the South Downs National Park kick-off this episode.
The TV programme opened with the feature on the crystal-clear waters of chalk streams in Hampshire within the pristine landscape and with these opening remarks “Chalk streams are a resource to be treasured and protected; they are almost unique to Southern England.” Countryfile visits Cheriton in the Hampshire, part of the South Downs National Park, through which the river Itchen flows from its nearby source. We see volunteers working to keep the water clear. Over recent years they have transformed the stream keeping it clear and free flowing. An expert shows us how to test for pollution from ‘brightening agents’ used in washing machine powders and liquids which could enter water courses through broken pipes.
