Environment Agency

Environment officers have been investigating the pollution since yesterday (June12) afternoon after receiving reports that the stream that runs down to the start of Calshot marshes had turned black in colour.

The Environment Agency has taken samples to try and identify the substance, and officers are currently assessing the extent of the damage to the watercourse.  It is believed that around three-quarters of a kilometre of stream has been affected.

John Elliot, senior environment officer said: “We are investigating the source.  We have ruled out natural causes as we don’t believe this is a natural occurrence.

“We are continuing to monitor the waters, but it looks like the incident has already caused a lot of damage to wildlife and the eco-system. 

“I am appealing to anyone who may be able to give me information about how this black substance got into the stream.”

The Environment Agency has notified the Department for Environment, Food and Rural Affairs (DEFRA) and the Food Standards Agency.

Doctor Ian Blair of the Health Protection Agency has visited the scene of the pollution and said:

“As a precaution to prevent any possible health effects the polluted area has been closed to the public, and warning signs to keep out are being put up. As a precautionary measure I am advising that watersport activities, including fishing, in the area of the Calshot creek are not undertaken until further notice. If anyone feels that they have had health effects as a result of exposure to the affected area they should call NHS Direct on 0845 46 47.”

Leader of Hampshire County Council, Cllr Ken Thornber, said:

"All water based activity in the area of the creek only has been suspended at Calshot Activity Centre. This is not affecting the activities courses being enjoyed by the young people at the centre as Calshot has an enormous range of land based and indoor activities which are continuing."
