Nova Scotia's acting auditor general says the provincial department responsible for monitoring drinking water safety in Nova Scotia isn't doing an adequate job.

Acting auditor general Alan Horgan is recommending Nova Scotia's Department of Environment make 19 changes to improve the situation.

The problems highlighted in a report released Wednesday include water supplies not being tested frequently enough, not properly auditing the work of those responsible for those systems, and a lack of follow-up when problems are found.

Horgan says municipal facilities are generally audited every three years as required, but so-called registered facilities are not.

These 1,600 registered water supplies are overseen by the Department of Environment and are typically used by restaurants, apartments, campgrounds, schools and nursing homes.

Horgan says some inspectors either aren't following proper procedure or there are no procedures for them to follow.

For example, Horgan says there have been instances when water samples were not obtained from facilities within 30 days after a boil advisory was lifted.

That's why he's recommending more training and better direction for those inspectors.

The province is quick to say Nova Scotia's drinking water does meet Health Canada guidelines.

But the province does agree with all 19 recommendations put forward by the acting auditor general and is promising to fix those problems as soon as possible.
