However, as noted by the company that ran the test, MCPS had tons of crumb rubber dumped on to the Walter Johnson HS artificial turf field the very day of the new GMAX testing.
Of course the GMAX readings improved from the previous test on July 11th.
The new GMAX report still describes a field that is dangerous, overused (and this is before BCC football was added to the field for this year) and in need of repair and/or may need replacement during the warranty period.

The new readings still show GMAX numbers that are not acceptable, even by FieldTurf's own standards.
In 2009, FieldTurf made this video about artificial turf safety and stated that their fields maintain GMAX ratings of 120-180 for the life of their warranty. The WJHS artificial turf field still has readings over 180, even after tons of crumb rubber was added the day of the most recent GMAX test.
