Government
Policies on Lead in Drinking Water in Australia
Comments and collation
of policy extracts by Elizabeth O'Brien, National Coordinator, The LEAD
Group Inc
It is unacceptable for public authorities to turn their
interest and funds away from the lead issue without having
implemented their own policies. What happened to the
recommendations of the National Strategy in Reducing Lead Exposure
in Australia, to "Implement a pilot program for testing lead
in first flush drinking water, rainwater tanks and drinking
fountains; conduct education programs to inform home handy persons
of the dangers in using lead solder in plumbing and review
drinking water guidelines for lead in context of an overall lead
reduction strategy" ??? The LEAD Group Inc. invites anyone to
show that any single lead in drinking water strategy planned in
the following 5 government policies has been carried out
adequately and to completion.
Further,
on the basis of one Victorian study that found one in every four
rainwater tanks tested in Victoria had lead levels at or exceeding
the Australian Drinking Water Guidelines, and knowing that 13% of
all Australian households use rainwater tanks for drinking water [Reference:
"Guidance on the Use of Rainwater Tanks" by David
Cunliffe (1998)], it can be extrapolated that over 600,000
Australians have too much lead in their drinking water.
When
one in four tanks is likely to be lead contaminated, a much greater
effort at education, lead testing of tankwater and blood lead testing of
exposed people needs to be undertaken.

Recommendation
8: Implement pilot
program for testing lead in first flush drinking water, rainwater tanks
and drinking fountains. Conduct education program to inform home
handypersons of the dangers in using lead solder in plumbing. Review
drinking water guidelines for lead in context of an overall lead
reduction strategy.
Rationale
: Despite widespread
confidence among water industry professionals about the low level of
lead in Australian water, there is virtually no evidence about the lead
content of first flush water in homes and drinking fountains. Testing of
drinking water is almost exclusively, focused on water sources and
distribution systems. If lead is present in drinking water, it will not
be detected in these tests because its likely source is household
plumbing; commonly lead solder used with brass fittings or copper pipes.
Even
where tap water is tested for lead, standard procedures involve
measurement of running water. Lead from plumbing shows up in first flush
tap water, that is, water drawn after the system has been standing idle
for several hours or overnight. A small test in several Australian
cities found that although most samples had very low lead content, a
very high level (up to 64 µg/litre) was found in some cases. Given the
hazard posed to children by levels of lead in drinking water, there are
good reasons for immediately undertaking a pilot sampling program to
determine lead levels from first flush water in homes and drinking
fountains used by children.
Although
the contribution of lead in water to blood lead level is relatively
small in comparison with that of lead in petrol, an overall lead
strategy should examine the contribution from all sources and the
potential for reduction. The potential for reducing lead exposure from
each source must be examined. Only by considering all sources together
will it be possible to determine the appropriate guideline for lead in
water. (For impacts, see page ES-34.)
Principal
agencies: NHMRC, Water
Resources Council. Others involved: Water authorities, State
health departments, consumer organisations.
Major
activities:
-
Develop
and implement pilot program for testing lead in first flush water.
The program should target houses most likely to have conditions
generally associated with high lead levels in tap water.
-
Develop
and implement pilot program for testing rainwater tanks to determine
if lead is a problem in drinking water from tanks.
-
Develop
and implement pilot program for testing water from drinking
fountains, particularly first flush water.
-
If
the results of the pilot programs indicate that lead is present in
water from taps, rainwater tanks or drinking fountains, develop
appropriate programs of remediation. Prepare and conduct public
education program aimed at home handypersons to warn of dangers in
using lead solder in plumbing. This issue should also be one aspect
of the program for renovators.
-
Review
drinking water guidelines in context of maximum overall lead intake
that will permit achievement of the blood lead level goal.
Timetable:
Immediately develop
and implement pilot drinking water testing program. Immediately prepare
and implement public education program on dangers of lead solder use.
Immediately begin examination of maximum lead intake to achieve goal, including
contribution of drinking water.

That tank water in rural communities and on individual rural properties
be randomly tested for lead content by an appropriate authority.
Lead
in Plumbing Products
85.
Due to the differing views given in evidence, the Select Committee
recommends that further testing for lead in first flush drinking water,
rainwater tanks and drinking fountains ("bubblers") in
schools, high rise buildings and older urban areas be undertaken.
86.
That the NSW Government conduct an education program to inform home
handy persons of the dangers of using lead solder in plumbing.
Other
Lead Exposures
96.
That the Select Committee supports the implementation of the remaining
recommendations of the New South Wales Lead Management Action Plan 1994.
97.
That the Select Committee supports the implementation of the
Recommendations of the nine Interdepartmental Working Groups Reports [ie
any omitted or altered during the synthesis into the New South Wales
Lead Management Action Plan 1994 – as listed below, from Appendix 4 of
the Report of the Select Committee]:
Data
Collection
Both the TR [Report
of the NSW Interdepartmental Lead Taskforce 1994] and the
LWaterWWGR [Lead in Water and Wastewater Working Group Report] recommend
a water sampling program but, whereas the TR gives examples of areas to
be sampled high rise buildings, schools and old urban areas, the
LWaterWWGR gives high rise buildings, schools, bottled water and
rainwater tanks.
Materials
and Standards
The TR omitted the
following recommendation of the LWaterWWGR: "that water supply
authorities and individuals take action to reduce the lead present in
systems under their control whenever the opportunity arises".
Education
The LWaterWWGR
recommends that the education campaign should clearly describe the
relative risks and importance of different lead sources and the
interaction between the components.
The
Lead Education Working Group Report recommends "that Local
Government includes in all Building Applications, information on lead
paint and plumbing issues. This issue should be developed by the
institute of Environmental Health with input from the proposed Lead
Reference Centre, Councils, Community, Industry and the EPA."
