Explanation
Not all risks can be easily assessed using a methodology (e.g. a ‘semi-quantitative’ risk matrix), where a risk is estimated in terms of likelihood of the hazard occurring, and severity of the consequence should the hazard occur. Some risks do not lend themselves to be assessed via narrow definitions of likelihood (e.g. estimated occurrence is ‘monthly’) or consequence (e.g. estimated severity is ‘moderate’ public health impact). For example, potential negative feedback from consumers regarding issues that may not have a significant impact on health may be viewed as a significant risk to a utility’s reputation and therefore should be addressed for the WSP. Sometimes, it may be more appropriate to assess risk in a simplified format (e.g. ‘significant’, ‘non-significant’ or ‘uncertain’) based on a group decision.
Whatever method is used, it is imperative that the risk assessment methodology is sufficiently clear and detailed to allow consistency (WHO/IWA 2009).
