Natural Resources Wales is dealing with an oil pollution incident in the stream at the north end of Broad Haven Beach near Haverfordwest in Pembrokeshire (not to be confused with Broadhaven South, near Bosherston).
The Coastguard has cordoned off the area where the stream flows onto the beach and people, especially dog walkers, are advised to avoid the area and not to come into contact with the water.
Initial investigations on Thursday, February 23 with Pembrokeshire County Council have not revealed the source of the pollution, but it is possible it could have been caused by a damaged heating oil tank.
Ioan Williams, Duty Manager for NRW, said: “We’re advising people to stay away from the polluted stream and for dog walkers to ensure their dogs do not enter the water.
“Our officers have started a clean-up of the stream and put in place an absorbent oil boom. They have also knocked on doors in the area to inform local residents and to ask them to check their heating oil tanks and associated pipework for any signs of a leak.”
Amber Horton, Environmental Public Health Scientist from Public Health Wales, said: “It’s unlikely that anyone exposed to the oil for a short period of time will have any adverse health effects, but it is still sensible to avoid contact with oils or the water in contaminated areas.
“If anyone gets oil on their skin, they should remove any affected clothing and wash using soap and water and if they feel unwell seek medical attention.
“We would also advise that all pets are kept out of contact with the oil and that members of the public do not pick up any birds or other animals affected by oil from the shoreline.”
Anyone with information about the pollution should call NRW’s 24/7 incident line on 03000 65 3000.
