The International Boundary and Water Commission is injecting ozone into the river to combat pollution.
The International Boundary and Water Commission kicked off a pilot project this month to improve the water quality in the heavily polluted Tijuana River. However, local elected leaders and scientists are concerned the project could do more harm than good.
to use ozone to remove contaminants from Tijuana River flows," The IBWC said in a statement sent to NBC 7."This technology has the potential to reduce the exposure of Americans to Mexican sewage by killing bacteria and reducing hydrogen sulfide levels.”Hydrogen sulfide levels have reached dangerous levels along the Tijuana River as it flows through the Tijuana River Valley near hundreds of homes and several schools and businesses. “My concern is that there's not enough safeguards,” said District 1 San Diego County supervisor Paloma Aguirre. “Scientists have expressed concerns around what type of reactivity and byproducts it could create.” Aguirre said leading researchers alerted her to the belief the IBWC is not monitoring the water or air during its 60-day pilot project. “They are doing a pilot experiment and bubbling a reactive gas into this polluted river with thousands of changing chemicals, with no air monitoring, no communication with the community or health agencies, no safeguards and no idea what they are producing or releasing into the air,” explained Kim Prather, a renowned atmospheric chemist at UC San Diego. “This is reckless and unacceptable to do for the first time in the middle of these South Bay communities who have endured more than enough." “If she is expressing concerns, I'm concerned,” added Aguirre, who has a master’s in marine biodiversity. “I find the fact that they're wanting to use my constituents as guinea pigs irresponsible.”NBC 7’s request for an interview with an IBWC representative was rejected, even though Commissioner Chad McIntosh was in San Diego on Wednesday. A statement from the federal agency did not answer any of NBC 7’s questions about safeguards and monitoring. The Environmental Protection Agency also sent NBC 7 a statement that did not address the same questions.Immigration
