For the second time in six months, Palm Island residents have been issued an emergency alert not to drink the tap water.
This comes in the wake of the installation of a $1.4 million water treatment plant for the region in 2017, which Palm Island Mayor Alf Lacey claims is already in need of repair.
Councillor Lacey believes the pipes in the community's reservoir are to blame for the recent discolouration, as they were installed in the 1970s.
