Imagine the school nurse calling you tomorrow with this message: Your child needs a new medication. We picked it ourselves. We didn’t ask a doctor. We don’t have any pediatric studies on it. But we’re confident it’s safe.
You would not accept that answer.
That is the standard the Sacramento City Unified School District is applying to the artificial turf field scheduled for installation at Crocker/Riverside Elementary in May 2026.
The admission
On March 19, 2026, in response to a parent’s written question, Assistant Superintendent of Facilities Chris Ralston confirmed that no allergist, no pulmonologist, and no pediatric medical specialist was consulted before the district selected the specific artificial turf product and infill material proposed for an elementary school playing surface.
On April 8, 2026, Ralston confirmed that this is the district’s standard approach. No medical review. No specialist input. For any of SCUSD’s artificial turf installations.
The product is unstudied
The infill material proposed for Crocker/Riverside is crushed olive pit. Ralston has described it in writing as “a new product” that he personally believes is “better than crumb rubber and cork.”
There is no independent peer-reviewed pediatric safety study of olive pit infill. None. The Partnership for Healthy Playing Surfaces — a research organization that catalogues artificial turf safety data — has specifically flagged olive pit crumb for “concerns related to allergies and respirable fibers.”
The district has pointed to one government study to support the safety of artificial turf: the California Office of Environmental Health Hazard Assessment (OEHHA) study. That study evaluated crumb rubber, not olive pit infill. And on March 25, 2026, Ralston himself acknowledged in writing that the study population “is not the same to compare” with elementary-age children — because elementary-age children “are closer to the ground.”
In other words: the one study the district cites doesn’t cover the product being installed, and doesn’t cover the children who will play on it.
The district had two-year-old written notice of heat illness at this exact field
Here is the part of the record that should stop every parent reading this article.
On March 19, 2026, Ralston disclosed in writing that two years earlier, a Crocker/Riverside family had formally notified the district that the existing field had caused heat illness in their student. The district was on written notice. They had two years to act.
The district’s response, two years later: replace the surface with one that runs significantly hotter.
How much hotter?
Independent research consistently documents artificial turf surfaces reaching 140°F to 200°F on hot days — 60 to 70 degrees Fahrenheit hotter than natural grass under the same conditions. A 2016 Penn State study measured artificial turf surface temperatures at 35 to 55 degrees hotter than natural grass even on mild days.
Sacramento regularly exceeds 100°F in late August, September, and early October — exactly when school is in session. At 100°F ambient air temperature, artificial turf surface temperatures of 160°F or higher are routine, not exceptional.
For comparison: 140°F causes second-degree burns on bare skin in about five seconds. Children fall on playing surfaces. Children touch playing surfaces. Children sit on playing surfaces during recess.
What was never asked
No allergist was asked whether olive pit infill might trigger reactions in children with tree-pollen sensitivities — a known concern in Sacramento, where olive trees are widely planted as ornamentals and olive pollen sensitization rates are high.
No pulmonologist was asked about respirable fibers from synthetic turf carpet during the kind of vigorous play that defines elementary recess.
No pediatrician was asked whether elementary-age children — who, as Ralston himself acknowledged, are “closer to the ground” — face exposures different from the adults and adolescents in existing studies.
No heat illness specialist was asked how a 60-to-70-degree increase in surface temperature would affect children at a school that already had documented heat illness.
The district made a medical decision without consulting a single medical professional.
Why this matters
The district is not required to be a medical research institution. It is required to apply ordinary care before making decisions that affect children’s health. Consulting a doctor before specifying a synthetic surface for elementary-age children is not an extraordinary step. It is the minimum.
The Sacramento City Unified School District Board of Education can require, before any further action on this project: an independent pediatric medical review of the proposed product, the proposed infill material, and the heat exposure conditions specific to this school.
That review has never happened. It can still happen — if the Board hears from enough families to require it.
