NASA Technology Illuminates Sewage Crisis in Tijuana River
Imperial Beach, CA – A groundbreaking use of NASA technology is bringing critical insight into the sewage contamination crisis plaguing the Tijuana River, which has been a persistent issue since authorities closed local beaches due to pollution in November 2014.
Published in the journal Science of the Total Environment, researchers utilized data from the Earth Surface Mineral Dust Source Investigation (EMIT), a satellite technology originally designed for mineral mapping. EMIT measures light wavelengths, enabling scientists to identify not just mineral compositions, but also harmful bacteria and pollutants in the Tijuana River sewage plume entering the Pacific Ocean near Imperial Beach.
Imperial Beach Mayor Paloma Aguirre expressed alarm over the findings, emphasizing the ongoing health risks faced by local families. "The science is clear, the health risks are real," Aguirre stated, calling on San Diego County to invest in essential infrastructure to protect public health.
The Tijuana River, which discharges millions of gallons of treated and untreated sewage, has been a significant environmental concern for residents. With recent EMIT observations revealing the presence of toxic cyanobacteria, health risks are elevated, as exposure can lead to severe symptoms including nausea and respiratory issues.
EMIT’s capabilities could significantly enhance pollution monitoring, allowing for timely analysis without the need for costly field samples. Eva Scrivner, the lead author of the NASA report, described the findings as a "smoking gun," pointing out glaring data gaps that need addressing.
As Aguirre campaigns for a county Supervisor position, she criticized local politicians’ inaction, stating, “If the county can’t take serious action on a sewage crisis we can see from outer space, maybe it’s because the county politicians downtown are living on another planet.”
With the ongoing wastewater crisis, the integration of advanced satellite technology shines a crucial light on environmental degradation, urging action for public health and safety.
