I). li-j I'di'li?rml u, .lfx'lT [1-5 1 I Ii ?r Dr. Robert Levin COUnty Public Health Officer 22 3/24/2015 Public Health Public Health has been researching health impacts of pesticide exposure at the Rio Mesa High School area. Have examined existing local data sources, discussed with local partners and state resources (VCOE, Gold Coast HCP, CDPH, California Cancer Registry). No data found indicating a potential health issue connection with pesticide use near high school. Public Health Appears there is a paucity of existing local, reliable data on health impacts of pesticide exposure use near this school. Public Health open to additional information, such as the result of school certain school ?surface? testing we are aware is occurring. Will monitor such testing bring back related recommendations as appropriate. 23 Mike Villegas APCD Officer 3/24/2015 24
