Synthetic Turf Fields †“ Lead Content Testing Results
Â
The following report has been reviewed and endorsed by the Chief Administrative Officer.
Â
RECOMMENDATION:
Â
THAT this report be received for information.
Â
PURPOSE:
Â
To provide information relative to heavy metal testing of the existing synthetic turf fields
in Delta and the analysis of these results by the Fraser Health Authority and the BC Centre
for Disease Control.
Â
BACKGROUND:
Â
At the April 28, 2008 Regular meeting, Council received a report on synthetic turf lead
content. That report focused on the differences between Delta†™s fields and those that
were found to contain high levels of lead in New Jersey. The report stated that despite
the research, Delta would be conducting its own testing on the synthetic turf fields, as well
as the adjacent soil based fields.
Â
This report provides an overview of the independent environmental consultant†™s metal
analysis of Delta†™s four synthetic turf fields, along with Fraser Health Authority†™s
findings and recommendations regarding the potential health concerns associated with
synthetic turf fields.
Â
DISCUSSION:
Â
Delta†™s Turf Field Analysis
Pacific Environmental Consulting gathered samples of turf fibers and rubber crumb
material at each of Delta†™s four synthetic turf fields. Composite soil samples were also
taken from adjacent natural turf playing fields at each location.
The consultant†™s analysis confirmed the presence of elevated levels of lead,
chromium, and zinc in some components of Delta†™s artificial turf fields (primarily in the
coloured lines†™fibers). However, the consultant†™s report concludes that there is
†œno reason to stop using these fields†•, on the basis that:
Â
 Pigments in the fibers containing the lead are in the form of lead chromate, which
is highly insoluble and thus has very low bioavailability. It means that it is difficult
for the human body to absorb this compound;

Lead chromate is fixed in place in the fibers and leaching of heavy metals does not
occur; and

Air monitoring tests have been conducted on synthetic turf fields in other studies
and no detectable levels of airborne lead or lead chromate was identified.
Â
All results from the soil samples analyzed were within the applicable criteria. A full copy
of the analysis and conclusions is provided in Attachment A.
Â
In so far as chromium and zinc is concerned, Pacific Environmental Consulting noted that
these metals are essential nutrients and that based on their research the public health
risk appears to be negligible. To validate the conclusions of this report, staff forwarded
the report to the Fraser Health Authority for comments and review. This is discussed
further below.
Â
Regional Health Risk Assessment
Based on growing concern by municipalities across the region, the Fraser and Vancouver
Coastal Health Authorities and the BC Centre for Disease Control (BCCDC) conducted a
joint risk assessment to assess the potential health risks associated with synthetic turf
fields throughout the region. The Pacific Environmental Consulting report, pertaining to
Delta†™s synthetic turf fields, was provided to the Fraser Health Authority as
background information for the study.
Â
As part of their risk assessment, the BCCDC has reaffirmed the methodology, and
conclusions of earlier analysis undertaken by the Consumer Product Safety Commission
(CPSC) which mimicked child exposure to lead by way of a hand to mouth
pathway. This analysis evaluated a variety of artificial turf field materials installed
between 1999 and present, with varying concentrations of lead. In every instance, the
estimated potential of lead exposure for children playing on synthetic turf fields did not
exceed the accepted maximum ingestion level of 15 micrograms.
Â
Recognizing that the range of lead concentrations and overall age of the turf field samples
evaluated in the CPSC analysis were equal or greater to that which are existing within the
areas governed by the Fraser and Vancouver Health Authorities, it was concluded that:
Â
 The health risk associated with exposure to lead in artificial turf is low; and

There is no strong health rationale to remove and replace existing synthetic turf
fields.
Â
Correspondence from the Fraser Health Authority, dated September 23, 2008, and the
associated report from the BC Centre for Disease Control, pertaining to the potential
health risks associated with synthetic turf fields has been provided as Attachment B.
Â
The Fraser Health Authority concludes that there are no significant health concerns
related to the presence of lead and other metal in some artificial turf fields.Â
Â
CONCLUSION:Â Â Â Â Â Â Â Â Â Â Â Â Â
Â
While the results of the heavy metal content analysis undertaken by Pacific Environmental
Consulting confirm the presence of lead, chromium and zinc within some components of
Delta†™s synthetic turf fields, further analysis by the Fraser Health Authority and the
BC Centre for Disease Control has concluded that levels of lead and other metals
observed, poses no significant public health risk to field users.
