San Diego Foundation Grants $740K to U.S., Mexico Nonprofits Building Coastal Resilience and Preserving Local Watersheds
Congratulations to Natalie Mladenov on her new grant.
San Diego Foundation (SDF) has awarded $740,000 in grants to U.S.- and Mexico-based nonprofits to support eight climate resilience projects in the Cali-Baja region that extends from Oceanside to Ensenada.
The Mladenov's grant is a partnership between San Diego Coastkeeper, San Diego State
University , and Proyecto Fronterizo de Educacion Ambiental ($100,000 total) that
supports the second phase of the One Coast, One Community project, which prioritizes
environmental issues affecting the safety and health of those living in or using the
coast, reduces environmental vulnerability in binational coastal communities and promotes
public-private partnerships.
Submerged monitors get a quick read on Tijuana River wastewater
More than two years of testing has researchers convinced they have a faster way to detect untreated sewage in the Tijuana River.
The new tools are called fluorescence monitors. San Diego State University (SDSU) 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.
The sensors emit UV light that’s reflected by the chemicals in wastewater that give it a unique optical signature.
Environmental engineering professor Natalie Mladenov has partnered with geography professor Trent Biggs, also at SDSU, on the two-and-a-half year project. They’ve published a paper in the journal ScienceDirect.

Research on DDT's Impact on Southern California Marine Life
Congratulations to Blue Gold faculty member Eunha Hoh and the team.
Her co-authored paper, "Identification of DDT+ in Deep Ocean Sediment and Biota in the Southern California Bight," was published in ES&T Letters in May 2024. It was introduced by the LA Times both online and on the front page of their print version.
Margaret Stack, her research staff, is the paper's first author. She was interviewed by LAirst Airtalk (NPR show/podcast) about the published work, and Dave Valentine’s (UC Santa Barbara) interview followed,
explaining the meaning of the work.
SDSU to build One Water Living Learning Laboratory at SDSU Mission Valley River Park
A $2 million grant from San Diego River Conservancy will fund a workforce training facility tackling water issues with innovative technologies.
The new laboratory will allow SDSU students hands–on experience with cutting-edge technologies for studying water quality, stormwater treatment and wastewater reuse. It will also have spaces for family-friendly exploration of water issues and learning opportunities designed for K-12 students.

Sea Level Rise Imperils South San Diego County Sewers
SDSU engineers tackle the impact of climate change on sewer systems in Imperial Beach and other underserved coastal communities.
Sewage overflows from Tijuana have been contaminating Imperial Beach for many decades. The problem recently reached crisis levels, with city leaders calling on the state and federal governments for more funds to fix the aging sewage infrastructure on both sides of the border.

Link Between the Salton Sea and Seismic Activity on the San Andrea Fault
Congratulations to Matt Weingarten and his group's work on Lake Cahuilla and earthquakes. The paper was published this summer in Nature and co-authored by Ryley Hill, Matt Weingarten, Tom Rockwell, and Yuri Fialko.

Toxic microplastics found where the rubber meets the road
The parts of your tires that get left on the road as you drive your car are a huge source of microplastic pollution, and some of it is toxic.
Researchers at San Diego State University (SDSU) have identified 60 chemical compounds in tires that end up in tire waste. And half of them had never been associated with tires before.

SDSU Research Spotlight - Dr. Alicia Kinoshita
Dr. Alicia Kinoshita runs a strong multidisciplinary research program in water resources and hydrology and her Disturbance Hydrology Lab focuses on the impacts of natural and human disturbances on surface water. She has a long-time commitment to undergraduate instruction, through courses, research and professional activities.
Study Finds Sewer Leaks Responsible for Beach Closures
A study by SDSU researchers finds that the bacterial outbreaks in the San Diego River that force frequent local beach closures are caused primarily by leaks in aging sewer pipes, not by homeless encampments or failing septic tanks.

COVID Research Study
Drs. Mladenov, Verbyla, and Sant have been funded by the San Diego River Conservancy and CSU COAST to evaluate the persistence of SARS-coronavirus-2 in natural waters.
Given that untreated wastewater can be introduced to coastal and riverine environments via sewer exfiltration, SSOs, illegal discharges, and ocean sewage outfalls, there is a need to better understand the persistence of SARS-CoV-2 in wastewater and surface water.
Their study seeks to quantify SARS-CoV-2 in wastewater and evaluate its persistence in the aquatic environment through spiking and degradation experiments combined with sample collection from waterways with known wastewater contamination.

Volunteer Position with AGU
AGU’s Thriving Earth Exchange (TEX) team is seeking scientists to join an innovative community science effort focused on citizen science, watershed education and restoration of Chollas Creek.
They are looking for a scientist to work with Kristen Hurst (GrounWork-San Diego) to help determine what kinds of data should be collected to document and analyze the health of the Chollas stream ecosystem. The scientist will work with the community to develop easy-to-understand and use protocols for data collection and data sharing that can be used widely by upper-elementary students and their parents. Your expertise with sustainable water resource solutions is a good match for this project.
The scientist must be available to meet the community leaders to discuss the work
and tour parts of the neighborhood. All work is volunteer/pro-bono and usually entails 2-3 hours of work per week, on average. Read the full description of the project.

Imagine a Day Without Water
Most Americans take water for granted. They turn on the tap, and clean water flows out. They flush the toilet, and dirty water goes away. Most Americans hardly think twice about the infrastructure that brings water to their homes, and safely returns water to our environment – but they should. The reality is, our water infrastructure is aging and failing. While most Americans cannot imagine a day without water, there are many communities that have lived, and are living, without water because they don’t have access to safe and reliable water systems. October 10th is Imagine a Day Without Water.
