‘Brown sea foam is harmless’ says Pembroke Power Station

A photograph taken on Wednesday morning (Jan 6) by Kaye Davies shows Hazlebeach completely covered by the foam.
PEMBROKE POWER STATION has released a statement saying that the high volumes of sea foam, currently being seen on some Pembrokeshire beaches, is harmless.
The statement was released in response to questions to operator RWE Generation UK from The Herald.
Photographs have been posted on social media by concerned locals, with some people calling the foam ‘disgusting’.
A photograph taken on Wednesday morning (Jan 6) by Kaye Davies shows Hazlebeach completely covered by the foam.
RWE Generation told The Herald: “At certain times of the year there is a noticeable ‘sea foam’ discharged from the cooling water system at Pembroke Power Station. Due to the current turbulent weather, including high winds and heavy rain the station is experiencing high volumes of ‘sea foam’.
“RWE are nearing the completion of a project to reduce the formation and release of foam from the station.
“This work is well underway with mechanical installation complete and commissioning which has been delayed because of bad weather due in the next few weeks. The project involves managing water levels in the cooling water system through the use of four large penstock valves similar to sluice gates.
“The ‘sea foam’ currently coming from the Pembroke Power Station cooling water outfall is the same as the sea and beach foam which occurs naturally from time to time. Even though it appears brown in colour we would like to reassure people that it is harmless and is not caused by any form of pollution.
“It is created by the agitation of seawater particularly when it contains higher concentrations of dissolved organic matter such as rotten leaves. This can create foam when combined with turbulent conditions that trap air, such as when seawater passes over a weir, the foam is not caused by chemicals or any other pollution.”
Paul Gibson, Industry Regulation Team Leader for South West Wales, Natural Resources Wales said told The Herald: “We are investigating reports of large amounts of sea foam on Hazel Beach in Pembrokeshire.
“This could be due to the operations of the power station and we are working with RWE Generation UK plc (RWE) to ensure the amount of foam generated is minimised.
“The foam produced is the same as that which occurs naturally and the unseasonably warm and stormy weather conditions over the Christmas and New Year may also have contributed to its generation.
“The sea foam has no environmental impact, although we understand it can cause concern.”

Swansea man dies weeks after release from troubled HMP Parc: Investigation launched
A SWANSEA man has died just weeks after being released from HMP Parc, the Bridgend prison now at the centre of a national crisis over inmate deaths and post-release failures.
Darren Thomas, aged 52, died on 13 November 2025 — less than a month after leaving custody. The Prisons and Probation Ombudsman (PPO) has confirmed an independent investigation into his death, which is currently listed as “in progress”.
Born on 9 April 1973, Mr Thomas had been under post-release supervision following a period at HMP/YOI Parc, the G4S-run prison that recorded seventeen deaths in custody in 2024 — the highest in the UK.
His last known legal appearance was at Swansea Crown Court in October 2024, where he stood trial accused of making a threatening phone call and two counts of criminal damage. During the hearing, reported by The Pembrokeshire Herald at the time, the court heard he made threats during a heated call on 5 October 2023.
Mr Thomas denied the allegations but was found guilty on all counts. He was sentenced to a custodial term, which led to his imprisonment at HMP Parc.
Parc: A prison in breakdown
HMP Parc has faced sustained criticism throughout 2024 and 2025. A damning unannounced inspection in January found:
- Severe self-harm incidents up 190%
- Violence against staff up 109%
- Synthetic drugs “easily accessible” across wings
- Overcrowding at 108% capacity
In the first three months of 2024 alone, ten men died at Parc — part of a wider cluster of twenty PPO-investigated deaths since 2022. Six occurred within three weeks, all linked to synthetic drug use.
Leaked staff messages in 2025 exposed a culture of indifference, including one officer writing: “Let’s push him to go tomorrow so we can drop him.”
Six G4S employees have been arrested since 2023 in connection with alleged assaults and misconduct.
The danger after release
Deaths shortly after release from custody are a growing national concern. Ministry of Justice data shows 620 people died while under community supervision in 2024–2025, with 62 deaths occurring within 14 days of release.
Short sentences — common at Parc — leave little time for effective rehabilitation or release planning. Homelessness, loss of drug tolerance and untreated mental-health conditions create a high-risk environment for those newly released.
The PPO investigates all such deaths to determine whether prisons or probation failed in their duties. Reports often take 6–12 months and can lead to recommendations.
A system at breaking point
The crisis at Parc reflects wider failures across UK prisons and probation. A July 2025 House of Lords report described the service as “not fit for purpose”. More than 500 people die in custody annually, with campaigners warning that private prisons such as Parc prioritise cost-cutting over care.
The PPO investigation into the death of Darren Thomas continues.

Woman stabbed partner in Haverfordwest before handing herself in
A WOMAN who stabbed her partner during a drug-fuelled episode walked straight into Haverfordwest Police Station and told officers what she had done, Swansea Crown Court has heard.
Amy Woolston, 22, of Dartmouth Street in Milford Haven, arrived at the station at around 8:00pm on June 13 and said: “I stabbed my ex-partner earlier… he’s alright and he let me walk off,” prosecutor Tom Scapens told the court.
The pair had taken acid together earlier in the day, and Woolston claimed she believed she could feel “stab marks in her back” before the incident.
Police find victim with four wounds
Officers went to the victim’s home to check on him. He was not there at first, but returned shortly afterwards. He appeared sober and told police: “Just a couple of things,” before pointing to injuries on his back.
He had three stab or puncture wounds to his back and another to his bicep.
The victim said that when he arrived home from the shop, Woolston was acting “a bit shifty”. After asking if she was alright, she grabbed something from the windowsill — described as either a knife or a shard of glass — and stabbed him.
He told officers he had “had worse from her before”, did not support a prosecution, and refused to go to hospital.
Defendant has long history of violence
Woolston pleaded guilty to unlawful wounding. The court heard she had amassed 20 previous convictions from 10 court appearances, including assaults, battery, and offences against emergency workers.
Defending, Dyfed Thomas said Woolston had longstanding mental health problems and had been off medication prescribed for paranoid schizophrenia at the time.
“She’s had a difficult upbringing,” he added, saying she was remorseful and now compliant with treatment.
Woolston was jailed for 12 months, but the court heard she has already served the equivalent time on remand and will be released imminently on a 12-month licence.

BBC apologises to Herald’s editor for inaccurate story
THE BBC has issued a formal apology and amended a six-year-old article written by BBC Wales Business Correspondent Huw Thomas after its Executive Complaints Unit ruled that the original headline and wording gave an “incorrect impression” that Herald editor Tom Sinclair was personally liable for tens of thousands of pounds in debt.

The 2019 report, originally headlined “Herald newspaper editor Tom Sinclair has £70,000 debts”, has now been changed.
The ECU found: “The wording of the article and its headline could have led readers to form the incorrect impression that the debt was Mr Sinclair’s personal responsibility… In that respect the article failed to meet the BBC’s standards of due accuracy.”
Mr Sinclair said: “I’m grateful to the ECU for the apology and for correcting the personal-liability impression that caused real harm for six years. However, the article still links the debts to ‘the group which publishes The Herald’ when in fact they related to printing companies that were dissolved two years before the Herald was founded in 2013. I have asked the BBC to add that final clarification so the record is completely accurate.”
A formal apology and correction of this kind from the BBC is extremely rare, especially for a story more than six years old.

Seam foam can be harmful particularly to dogs who run and play in it so dog walkers take care.
It can be polluted stormwater from rivers or drains discharging to the coast, sea foam formed on adjacent beaches can be polluted with viruses and other contaminants.
If crude oil discharged from tankers at sea, or motor oil, sewage and detergents from polluted stormwater are present, the resulting sea foam is even more persistent, and can have a chocolate mousse texture.
If the foam forms from the breakdown of a harmful algal bloom (including those caused by some dinoflagellates and cyanobacteria), direct contact with the foam, or inhalation of aerosols derived from the foam as it dries, can cause skin irritations or respiratory discomfort.
