Walkerton inquiry hears well No. 5 built without approval

The Walkerton inquiry has heard that the town's now infamous well No. 5 was built without approval from the province.

An approvals branch engineer with the Environment Ministry testified Wednesday that the move was highly unusual and that the town was admonished for it.

The shallow well was considered vulnerable to pollution. It's just 15 metres deep.

The Ministry issued a certificate of approval after the well was dug on condition that special chlorination piping be installed to kill bacteria. That was never done.

Last May's E.coli outbreak killed seven people.

It's believed that cattle manure from a nearby farm washed into well No. 5 and that the bacteria survived because of inadequate chlorination.
