The County said it and federal and local partners will host a Healthy Community Fair on Saturday, Nov. 14, 2026, at the Imperial Beach Library to help the public learn about work addressing pollution in the Tijuana River Valley.

Participating organizations include the U.S. Agency for Toxic Substances and Disease Registry; the San Diego County Air Pollution Control District; San Diego State University; University of California San Diego; the Tijuana River Coalition; and the County of San Diego.

The event runs from 10 a.m. to noon at the Imperial Beach Library, 810 Imperial Beach Blvd., Imperial Beach, CA 91932.

Spanish and English interpreters will be available. Attendees can meet staff, learn about current research and access available community resources.

Information on recent reports will be available, including the County’s Tijuana River Valley Economic Impact Study and ATSDR’s report on Hydrogen Sulfide and Odors in the Tijuana River Valley; organizers also expect to release results from the second CDC Community Assessment for Public Health Emergency Response, known as CASPER, later this year.

Residents concerned about health, odors or local economic impacts can use the fair to speak directly with agency staff and pick up report summaries and local resource information.
