The University of Lagos has launched an investigation into the quality of water supplied to its hostels after students, particularly those in female halls of residence, reported cases of vomiting, stooling and skin related reactions they attributed to the campus water supply.

The university's Head of Communication, Mrs Adejoke Alaga Ibraheem, confirmed in a statement on Wednesday that relevant departments had commenced a thorough assessment of the water supply system, including laboratory tests, to determine the accuracy of the reports and identify any potential health risks.

"The attention of the University of Lagos Management has been drawn to reports on the alleged contamination of the campus water supply in some halls of residence. We wish to assure all students, staff and members of the campus community that the matter is being treated with utmost urgency and seriousness," the statement read.

The university added that immediate interventions had been put in place to protect the health and safety of students while investigations continued, with updates to be communicated through official channels.

The University of Lagos Students' Union had earlier issued its own statement on Tuesday, signed by its President, Akinpelu Bolaji, disclosing that an inspection of one hostel block had traced discoloured water to a borehole serving that block. The university subsequently suspended water supply from the affected source and provided alternative arrangements for residents.

The union, however, clarified that no definitive link had been established between the reported illnesses and the hostel water supply. "According to medical personnel at the University Medical Centre, the cases that have been presented and assessed thus far have not been medically linked to our water supply, and some of the cases involved students who live off campus," the statement noted.

Water samples collected from the hostels had been sent for laboratory analysis, with results expected within 48 hours of the union's Tuesday statement. The Students' Union urged students to remain calm and withhold conclusions pending the outcome of the tests.

"At this time, investigations are still ongoing, and no definitive link has been established between the reported health cases and the university's hostel water supply," Bolaji stated.
