The paper aims to investigate storage conditions and differences in the microbiological content of tap and bottled water in Northern Ireland. Risk assessments were adhered to by employing key control measures such as Personal Protective Equipment. The funnel methodology was employed for literature search and review. Hazard and risk assessments, Control of Substances Hazardous to Health (COSHH) assessments and safety data sheets were all utilized in the collection and testing of samples. Tap and bottled water sampling were collected from across Northern Ireland. Even though there is no statistically significant difference, it does not mean the medium sized effect is unimportant in practical terms. All three failing bottled water samples were stored in unrefrigerated, shelved conditions. The fact Colony Count was higher at 22˚C than at 37˚C indicates no direct link between temperature and microbiological quality. This research recommends daily testing of bottled water. NI Water is raising awareness of water quality by challenging consumer perceptions. Clear microbiological contents labels on bottled water, review of bottled water as food product and the creation of a bottled water regulator to oversee and enforce new guidelines. Clear government information and advice is required for consumers in Northern Ireland and beyond, especially those with impaired health.
