Burst Sewage pipe affecting water quality on Tenby South Beach and nearby beaches.
A burst water pipe has led to some sewage flowing into the Ritec River affecting water quality on Tenby beaches.
Sea swimmers are being urged to avoid swimming in the area. Signage will be placed on the beaches today, Tuesday 2nd July.
An investigation has been launched by Natural Resources Wales (NRW). It said there was a potential pollution risk at Tenby South Beach, Castle Beach, Tenby North Beach and nearby Penally Beach.
"Dŵr Cymru Welsh Water has informed us of a burst rising main near Tenby which has resulted in sewage entering the River Ritec," NRW's Andrea Winterton said.
She said the main had been isolated, and that there should be no further pollution into the river from the burst pipe.
"Due to the potential for the pollution to impact the downstream bathing waters, we’ve declared an abnormal situation and informed Pembrokeshire County Council who will place signs at the beaches to warn people of the potential pollution risk," she added.
