EPA and CDPH address South Bay sewage issues and air quality concerns

Federal and local agencies are actively addressing air quality concerns in South Bay, linked to recent sewage issues from the border. The Environmental Protection Agency (EPA) has stated that despite earlier fears regarding hydrogen cyanide, assessments indicate no immediate health risks to the public. Strong odors remain in the area, but officials, including County Board of Supervisors Chairwoman Nora Vargas, have reassured residents that it is safe to be outdoors and attend school. Researchers from UC San Diego had reported elevated levels of toxic gases in South Bay neighborhoods, prompting a response from a Hazardous Incident Response Team. Their findings confirmed that there were no immediate public safety threats, allowing officials to focus on gathering public health data and conducting further research. The EPA is collaborating with local environmental health officials and the Air Pollution Control District to monitor the situation closely. While the risk of hydrogen cyanide is considered very low, additional monitoring for hydrogen sulfide levels is being implemented due to its potential health effects, such as headaches and irritation. The California Department of Public Health (CDPH) has also supported local health officials in this matter, emphasizing the need for ongoing monitoring of pollution impacts on public health and air quality. Dr. Tomás J. Aragón, the CDPH Director, highlighted the urgency of addressing the contamination in the cross-border river, acknowledging the prolonged crisis faced by residents.
