Also
that day, Liz Canning of the Department of Primary Industries, Water and Environment,
together with Dr Bicevskis wrote a brief for Mrs Jackson (pers comm with Liz Canning 16
Nov 2000) which stated, among other things:
Approximately
twenty samples [in total] of soil, dust and water were taken in the homes and yards of the
families with elevated lead in blood levels [from the Menzies Centre West Coast study].
These results did not indicate a clear source of lead in the local environment, but a
number of families were found to be living in homes with exposed lead-based paint, a known
cause of elevated blood lead levels in children."
Without
saying whether investigation of heavy metal contamination of soil was being carried out on
the West Coast, the brief states that "A number of [environmental] studies are being
carried out on the west coast as follows: National Pollutant Inventory, Savage River Mine,
and Mount Lyell Mine". According to Liz Canning (pers comm 16 Nov 2000) there
is no data on heavy metals in soils other than those included in the 20 samples mentioned
above. Mark Dawson, Environmental Officer, Copper Mines of Tasmania [the operators of the
copper mining at Queenstown] stated that his company does not have any soil monitoring
data at all and that for the current mining activities, they have an agreement with the
Tasmanian government that their mining company is not responsible for any previous
contamination from copper mines in the area. He also said that Wojciech Grun of Mineral
Resources Tasmania [previously called the Mines Department] has done some soil samples for
a map he is producing on acid mine drainage (pers comm 16 Nov 2000).
As
an example of the inadequacy of the National Pollutant Inventory (NPI) data, the only
heavy metal emission listed for Copper Mines of Tasmania on the NPI website http://www.npi.gov.au/ is that in June 1999 (the
only month for which any data is reported), the mine emitted 0.0062 kg of cobalt and
compounds to the air. There is no report for any heavy metals emitted to land or to water.
Yet
the ministerial brief's RECOMMENDATION is that "The above studies indicate that
investigation of heavy metals in the environment is occurring on the West Coast. The human
health studies have not indicated the need for further community wide environmental
assessment."
