Mapua Contamination – Secrets and Lies

by Catherine Delahunty

This week a Ministry of Health Report came out on the health effects of the dubious remediation at the toxic site in Mapua. The way the Ministry of Health’s media release read, glossed over the risks to the community, which could now be declared negligible.

I only had to read the Executive Summary of the report to get a totally different picture.

The report slams the Ministry for the Environment for failing to protect public heath. It establishes that only a small number of substances—mainly heavy metals—were monitored; it says these would not have had serious health effects.

Scandalously the company and MFE did not monitor the site and its surrounds for the dioxins, PCB’s and other organochlorine compounds that were spread in to the air. Some of these toxic chemicals were actually created by the malfunction of an experimental “clean” technology.

These “chemicals of concern”, as the report calls them, are infamous because there is virtually no safe level of exposure and they bio accumulate in the food chain.

The local people have been told that because there was no monitoring data collected no one knows the level of risk they have been exposed to. Because Dioxins and other dangerous chemicals have a long half-life (some more than 30 years) in the environment and our bodies there can be a wide range of intergenerational health effects—from cancer to reproductive disorders, immune related disease, diabetes and heart failure. While the Ministry of Health is calling for further testing and is working with the community on the issue their media statement mimics the negligence during the clean up has had negligible effects.

The only good thing is that the secret is out. People living through that noise and dust suspected they were being exposed to dangerous chemicals without monitoring, and they were right. What I don’t understand is why the Ministry of Health press releases would pretend this wasn’t true. Who are they trying to protect? Public health or perhaps the agencies responsible for a failed chemical clean up?
