What about SF's synthetic turf?

From the front page of today's SF Chronicle (US to mount multiagency study of health risks of synthetic turf):

...Citing health concerns, the Los Angeles Unified School District no longer uses crumb rubber on its turf fields, preferring alternatives like cork, while the New York City Department of Parks and Recreation also stopped using the recycled tires on new fields.

In San Francisco, a group of parents fought the Recreation and Park Department for years over installing turf fields with crumb rubber at Golden Gate Park. The fields were installed anyway, but opponents continue to push for alternatives — like used shoes or coconut fiber

Kathleen McCowin, who was arrested after staging a one-person sit-in at Golden Gate Park to stop construction of the Beach Chalet fields, said she’s not sure the federal agencies will answer the question many parents have...

Rob's comment: 

Well, what about it? Has the city's Recreation and Parks Department installed potentially toxic synthetic turf on our playing fields? 

Odd that the reporter didn't include a reassuring response from Rec and Park, which the Chronicle story seemed to require. Maybe there's no reassurance to be had. 

I can't find anything on the issue on the website, though I did find this.
