Researchers at San Diego State spent more than two years testing what they say is a faster way to detect untreated sewage in the Tijuana River Estuary.
Environmental engineering professor Natalie Mdladenov, in her lab at San Diego State, holds a fluorescence monitor, like the ones used to test for untreated wastewater in the Tijuana River on Aug. 21, 2024.
The new tools are called fluorescence monitors. San Diego State University scientists have submerged several of them beneath a platform in the mouth of the Tijuana River. They’re measuring pollution in a river estuary that’s notorious for fecal contamination. Mladenov said the technology is working and fluorescent testing on site is a lot faster than testing water samples in a lab.
She added they have checked the results of the submerged monitors against lab results, which showed the same results.
