Teresa DeAnda, Former Central Valley Coordinator

In addition to being CPR's coordinator in the San Joaquin Valley from 2003 until 2012, Teresa is the President and Director of El Comite Para el Bienestar de Earlimart, in Earlimart, a small farmworker town in Tulare County, California's Central Valley. El Comite educates local townspeople and those in other rural towns about the dangers of day-to-day pesticide drift and provides information about what residents can do in the case of a pesticide drift emergency. Teresa started the organization as a direct result of a drift accident that occurred in Earlimart in November 1999, when a toxic cloud of pesticides drifted onto her agriculture-surrounded community, making 180 people ill. Teresa has testified many times on the need for adequate response to poisoning events to the California Department of Pesticide Regulation. She spoke at CPR's February, 2003 Drift Conference on the theme, "Absolutely Never Do Nothing." Teresa is on the advisory boards of the Center for Race, Poverty and the Environment and Latino Issues Forum. She is bi-lingual (English/Spanish).
