After the Menlo Park City School District board in November received the results of a study that said the artificial turf fields at Hillview Middle School and Kelly Park pose an insignificant risk of cancer, parents asked for more study of the safety of ground-up recycled tires used as infill in the fields.
A consultant has returned to the district with a proposal for those further studies, including looking for substances the first study did not examine, and testing the air on the fields to see if inhaling it could cause a health hazard.
The research would cost a little more than $43,000.
The Menlo Park district's governing board will meet Tuesday, March 13, to decide if it will approve the additional tests. The meeting starts at 6 p.m. in the district's TERC building, 181 Encinal Ave. in Atherton.
At the November meeting a consultant told the board that it would cost between $250,000 and $375,000 to replace the ground-up tires, known as crumb rubber, with another substance on the Hillview field. Completely replacing the field would cost $750,000 to $850,000. The field is expected to last another eight years before it would need replacing.
The school district also checked with other schools to see what they have done with their playing fields.
The school district is part of a statewide study of the potential dangers of artificial turf fields; the results of that study are not expected to be available until 2019.
