Prohibitions against swimming Ballyloughane and Grattan rd. beaches have been lifted by the city council after further bacteria testing.
Water samples taken earlier this week were found to contain elevated levels of E.coli and Intestinal Enterococci bacteria.
The city council put a bathing prohibition in place after the tests, issuing a notice advising people not to swim.
Fresh samples were taken August 2 when the notice was issued, and have shown improved water quality according to the city council.
The prohibition has been lifted and both beaches are open to the public again.
