Meet Our Speakers: Gaby Gonzales-Olimón

“I was a Westie for a week,” explains Gaby Gonzalez-Olimón, Semester in the West’s Sonoran Institute host and guide while in Mexico.  Two years ago Gaby was interning as a wildlife biologist in Grand Canyon National Park when she met Semester in the West students and staff through a bison-surveying project on the North Rim.  Gaby grew up in Baja California and when the planned Spanish translator for the program’s Mexico section fell through, program director Phil Brick hired Gaby as the new translator.  Gaby drove from the Grand Canyon to Mexico to live and work with a group she had previously only known for a couple days.  Once in Mexico, Gaby interfaced with the Sonoran Institute, a nonprofit organization working in the United States and Mexico to connect communities with their natural resources and preserve wildlife and habitat.  The Colorado River Delta Program of the Sonoran Institute was so impressed by Gaby they created a new position, Environmental Education Coordinator, just for her.   Gaby develops and implements environmental education programs and community workshops on restoration in the Colorado River Delta area.  She loves to take students and kids out into nature.  Many of these kids have lived their whole lives in urban areas and are initially terrified and brought to tears by the unfamiliarity of nature.  As an honorary Westie, Gaby’s advice to Semester in the West students is to “network and keep in touch with the people you meet.”

Meet Our Speakers: Iban Leal and Edgar Carrera

Las Arenitas is one of two wastewater treatment plants outside of Mexicali in Baja California that processes the city’s water to be reused for irrigation. Iban Leal is a chemist and the manager of the facility which is under the jurisdiction of CESPM, the state water commission. Water is pumped into the plant at a rate of 840 L per second and then travels through a series of ponds. This system of twelve shallow rectangular ponds help filter and clean the water through aeration, sunlight, chlorine and different types of bacteria. 
    From the ponds, the water flows into a 200-acre wetland. Edgar Carrera, a hydrologist and environmental engineer from the Sonoran Institute helps manage this area. The series of wetlands demonstrates a mutually beneficial partnership between the water treatment plant, the Sonoran Institute and the species that inhabit the marsh. The cattails that dominate the area filter out the chemicals left in the water and provide a home for over 150 species of waterfowl. Once the water has circulated through the wetland for several weeks, thirty percent is diverted towards the Río Hardy and the rest is pumped back into the Mexicali Valley for irrigation. Las Arenita’s wetland is also used for educational purposes. School groups from Mexicali come here to walk an interpretive trail built in partnership with the Sonoran Institute and learn about the project’s success.
