Calif Prop 65 Settlement – Next Steps –
Last of the California – Prop 65 Turf Settlements Final July 16, 2010
Settlement Grants = Public Awareness Campaign from California Public Health Trust & Center for Environmental Health (CEH), reminding us of the risks of lead exposure and ideal solutions if lead is found on any surface.
CEH & the California Public Health Trust will invest settlement funds and initiate a public awareness & testing campaign; the focus being primarily on athletic fields, playground areas and daycare centers with “older” surface materials. California’s AG Reaches Settlement …
From the Desk of Annie Costa; Exec Dir;
“In today’s market, a brand that boasts of being “lead-free” is simply stating their products meet existing industry-wide, voluntarily accepted, product standards.
“Artificial grass solutions are delivered to market by system integrators [builders/installers] under a variety of brand identities – the AG and CEH are focused on a a finite number of older, existing fields; not on a specific company, brand or solution.
“If you want proof of a product’s total lead content (valid, total lead) you need to do an ASTM 2765, a total lead content test. This test result will provide the maximum amount of lead in the materials.
“We have found that XRF testing can overstate lead content results by 100 times or more – wipe testing only provides a snap-shot of the lead content on the surfaces, at the time the test is taken.
“Understanding test methods and what the results show, is critical – you can check this out in our member’s pages, keywords = lead (pb) testing.
“Everyone tests their products today, test results are kept on file – all you have to do is ask for them. That kind of transparency should speak volumes for the industry’s confidence that they are delivering materials that meet or exceed expectations.”
Steps Moving Forward
** A key guide of how to best manage lead exposure from artificial grass surfaces [with lead of 300ppm of more], Dr Leftwich, an ASGi Board Adviser, reminds us that the TIMING OF both testing and grooming are critical to accurate testing results.
Results of wipe testing will be dramatically different right after rain, snow or irrigation, so to obtain the most accurate results; tests should be done after extended play under dry weather and surface conditions.
The AGs office has also confirmed that Dr Leftwich’s informative white paper (.zip) was used in defining one of the key settlement options.
If the owner chooses to leave the field in place, on-going testing and grooming is an acceptable option, stated in one of the settlements. This speaks volumes of the confidence that the AG & DAs office’s’ has in this procedure protecting the public from elevated levels of lead, if found on a field or play surface. Please contact ASGi Board Adviser, Dr. Leftwich, with questions or for appropriate test kits.
Milo George, [PSFS.us], an ASGi Board Adviser,
suggests that grooming should include surface aggitation, applied, environmentally inert, treatments [such as enzyme cleaners and sanitizers using pel-free components], magnetic lines [to pick up cleats, bobby-pins, etc during grooming], and the re-application of fresh infill materials.
Depending upon the surfaces use, general grooming should occur monthly, with professional deep grooming completed 2 to 4 times a year.
General grooming would include brushing surfaces; enzyme treatments and materials removal and can easily be incorporated into the owner’s maintenance regime – bi-annual or quarterly deep grooming should be done by professionals, who bring the proper power tools to extract, groom and refresh surfaces without damaging them. Contact ASGi Board Adviser, Milo George, with your grooming and maintenance questions.
