A PROBE has been launched to find the source of fuel polluting a Hampshire river.

Monks Brook, which passes through Fleming Park in Eastleigh, is again contaminated with petrol, and an investigation has been launched to find the cause.

The strong-smelling substance can be seen on the surface of some parts of the river and it is advised that locals keep dogs and children away from the water.

This one of multiple occasions where fuel has been found in the river, but no one knows where the contamination is coming from.

The Environment Agency and Southern Water are appealing for any information on where the fuel is coming from.

A spokesperson from the Environment Agency said: "The Environment Agency is working with Southern Water in order to investigate the source of the pollution at Monks Brook in Eastleigh.

"We are concerned that a pollution incident has occurred again at this location despite thankfully no environmental impacts to the area.

"We urge members of the public to provide us with any details they may have about how fuel has entered the brook.

"If anyone has information about this incident they are encouraged to contact the Environment Agency’s 24 hour emergency hotline in confidence on 0800 807060."

In 2019, Pavilion on the Park, which is based at Fleming Park, said: "Warning: We have been alerted that there is environmental contamination in the river running past and through Pavilion on the Park, and Fleming Park.

"We have been informed that the Environment Agency and Southern Water are dealing with the situation.

"Please be cautious and don't let your dogs drink from or swim in the river unless you are sure it is safe for them to do so."

In August 2018, the same river was suspected to be contaminated by oil.

Jane Marucci, from Eastleigh, said she was walking her dog when she noticed an oily substance in the stretch of river.

Jane said: “There was a strong smell like paint and we thought it was a bit unusual around that area.

"“Normally you see a little bit of oil in the water as it comes off the road but never a lot.

"This time it was like someone had poured out oil in there.”

Both incidents were investigated by the Environment Agency.
