This award will support a natural experiment that will (1) examine the change in free drinking water access in Food Service Areas in California public schools from before to after Senate Bill 1413/Healthy Hunger Free Kids Act implementation; (2) assess changes in the proportion of schools with excellent water access and barriers and facilitators to providing excellent water access in a subsample of schools that have excellent and poor water access; and (3) investigate the addition of water language to district wellness policies over the past five years and if the strength/comprehensiveness of water language in the district wellness policy correlates with excellence in water access at the school.
