Mr. Tom Cuddy:

Quite a number of our sources are challenged. The basic raw water is not treatable fully, certainly by the older treatment plants. In many cases, the resolution is either to find a new source or extend a neighbouring network to connect up. When we do apply a boil water notice, it is for very good reasons. It may be because there are concerns about the risk to public health. It is not necessarily that there are pathogens. The difficulty of cloudiness means treatment with ultraviolet and chlorine cannot be fully effective. In fact, over-chlorination, which results in trihalomethanes, can be detrimental.

Let me address the question on tankering water. Unfortunately, when we tanker water to an area, that water also has to be boiled. Therefore, people would still have the same issue. The tankers themselves would need to be flushed out, cleaned and so on.
