Manx Utilities says it can't find any sewage leak on Peel beach after reports at the weekend.
Yesterday, 3FM reported a community group's claims to have found toilet paper, sanitary products and human waste on the shore.
But Manx Utilities says after inspections yesterday it's found potential problems with a buried manhole near the sea wall.
However, it says it doesn't think sewage caused foam along the beach but is continuing to investigate.
