Two cheers for Dr Verrall.

The Government has come to the conclusion that the local authorities in Dunedin have not been acting in a fit for purpose manner. So they are having an urgent review.

Dr Verrall was an academic public health physician before being parachuted into parliament on the Labour party list at the election. She knows the people involved. This gives her actions more weight.

The Government has ordered a rapid review of the health response to lead contamination in the drinking water supplying Waikouaiti and Karitane.
“New Zealanders have every right to expect that their drinking water is safe; what has happened in Otago is unacceptable,” Associate Health Minister Ayesha Verrall said.

A week ago, people living in Waikouaiti, Karitane and Hawksbury were asked not to drink tap water after an elevated level of lead was found in a raw water reservoir.

The review would report directly to director-general of health, Dr Ashley Bloomfield, and panel members and the terms of reference would be released shortly, Dr Verrall said.

“While it is vital that we understand how levels of lead contaminated the water, we also want to review our overall health response to the situation.

“The independent review will look into how the health system, including local and central government health agencies, responded to the situation and how the risk to public health was subsequently addressed.”

After the drinking water notice was imposed, it was discovered that a spike in lead measurements, of 40 times the acceptable level, was detected last year.

“Ultimately, we want to reduce the risk of this happening again and inform the ongoing response,” Dr Verrall said.

“I expect the director-general to report back to the Government on the preliminary findings and suggested actions by March.”

The review was ordered the same day that blood testing of an estimated 1500 affected residents started.

Southern District Health Board medical officer of health Dr Susan Jack said there had been a great response to the board’s call for people to have their lead levels tested and 282 people were tested yesterday.

The first batch of results was expected in two to four days, and collated results would be released for discussion at a community meeting in a fortnight.

Test results might help to establish the cause of the lead reading spikes in the water, Dr Jack said.

“As part of the testing, everyone is doing a questionnaire that will look at their specific risk factors, where they live, what sort of water supply they are on, if they only drink tap water from the local supply, if they have any hobbies or occupation which might lead to an elevated level, and putting that all together.”

A testing clinic operated by WellSouth will be open daily in the East Otago Events Centre until Friday, and the hui room at Karitane Old School will also be used for testing tomorrow.

Dr Jack said that everyone had some level of lead in their body due to environmental factors, and the tests were looking for abnormal levels of the metal.

Even if those were found the cause need not necessarily be the town water supply, as there may be other factors to consider, such as exposure to lead-based paint.

“Most people have very low levels of lead in their blood, that is completely normal as people have exposure from all sorts of things over the term of their lives, so older people tend to have slightly higher levels than children,” she said.

I agree that lead is cumulative, but we need to find our why. In the meantime, I’m buying water in a bottle.

I’m so confused. a) they find lead in the water supply reservoir, b) they test resident for blood levels of lead, c) they announce that testing people’s blood levels might tell them where the lead came from (see a), d) they announce that the lead might not be coming from the water supply (see a). What, did the lead bleed back to the reservoir from people’s contaminated bodies? Or am I totally misreading this?

The water is taken from a river, and then goes to various places. But assuming competence in a public body that is trying to be diverse is the work of fools

I’m betting they find out quickly. But why was it allowed?
