Advice against swimming at a beach in Devon has been lifted following a warning about sewage.
The agency said it was investigating after it detected “elevated readings of ammonia” at Exmouth Beach on Friday.
A spokesperson said the pollution had been found at Littleham Brook, which flows into the sea.
It said: “Our monitoring confirms that water quality returned to normal [on Friday] and is remaining stable so the precautionary advice against bathing has been lifted.”
