The Queensland
Department of
Environment and
Resource
Management
(DERM) report said:
On the basis of the
results from the
monitoring investigation,
the Bradken Resources
Runcorn Foundry site
did not appear to give
rise to ambient pollutant
concentrations in the
surrounding residential
community that would
pose a risk to human
health. This conclusion
has been endorsed by
the Queensland Health
Brisbane Southside
Public Health Unit.
A Queensland Department of
Environment and Resource
Management (DERM) ambient
air study has found little
evidence of health risks
associated with emissions from
the Runcorn manufacturing
facility in Queensland.
The report, released in May,
was endorsed by the
Queensland Health Brisbane
Southside Public Health Unit
and confirmed emissions
from the Runcorn foundry
were routinely at levels less
than half Australian Air Quality
Standard requirements.
Bradken environmental officer,
Greg Chaplin said the six-
month intensive ambient air
study around the Runcorn
foundry was undertaken in
response to concerns from a
small number of local residents.
“Bradken is an environmentally
responsible organisation with
our own strict environmental
policies and monitoring
programs. Ensuring our
operations comply with
Australian standards is a high
priority for us,” Greg said.
According to the DERM
Report, there was no
evidence the Runcorn
site was causing ambient
pollutant concentrations
posing a risk to human
health in the surrounding
residential community.
Comparative standards used
for the purposes of the study
were Australian Air Quality
Standards, Queensland
Air Quality Standards and
air regulations from the
Ontario Ministry of the
Environment, Canada.
The study tested for materials
known to be emitted from
foundries including dusts
(TSP & PM10), metals in
the dusts, Volatile Organic
Compounds (VOCs),
formaldehyde, HF and H2S.
Monitoring was done at three
locations about 300 metres
from the foundry. Locations
of the sampling sites were
selected to detect air
emissions in several directions.
Local residents were also
supplied with sample kits to
use in the event they detected
an odour – none of which
contained any gasses of
significance when analysed.
Significantly, the report noted
the importance of non-foundry
sources of the chemicals and
metals in the area.
“The findings of this
independent report affirm
Bradken, and in this case,
Runcorn, is operating well
within Australian standards
and causing no harm to the
environment,” Greg said.
With only a few exceptions,
all results were well below the
relevant standards, in many
cases less than 5% of the
standards. The exceptions
were during heavy dust
storms that affected the
entire region.
“It also confirms the results
of previous independent
environmental studies at other
Bradken sites that have found
environmental health risks
associated with emissions
were unlikely.”
