Water supply is 'safe' after Storey Arms chemical spill
Welsh Water has confirmed the public water supply is safe, after a chemical spill from a lorry on a main road in the Brecon Beacons.
Police and firefighters were called at 08:50 BST after around 500 litres of copper carbonate leaked from a parked container on the A470 near Storey Arms.
About 250 litres ran into surface water drains and the Beacon Reservoir.
Officers from Environment Agency Wales said there has been "minimal impact to fish life".
The spill has so far had a localised impact on wildlife, with seven dead fish reported where the chemical entered the reservoir.
John Harrison, of Environment Agency Wales, said the lack of damage was "thanks to the vehicle driver who acted quickly to help contain the spill".
Surface drainage system
The agency said it will continue to monitor Beacon Reservoir and the nearby stream to make sure there is no further impact over the next few days.
The Mid and West Wales Fire and Rescue Service said the leak was contained with the help of the Environment Agency.
The road was closed for about three hours.
Fire service hazardous materials officer David Sheppard said: "Crews were called to leak of approximately 500 litres of copper carbonate from a ruptured bulk container.
"The leakage entered the surface drainage system, but was contained using Environment Agency grab packs, dam mats, and absorbent granules.
"Six sets of breathing apparatus were used, along with hazardous material decontamination equipment."
