Recent wildfires in Los Angeles have destroyed over 10,000 structures, leaving parts of the Pacific Palisades, Altadena, Pasadena and other areas unrecognizable. As residents return home, ensuring access to safe drinking water is critical.
How wildfires affect drinking water
Wildfires can make water unsafe by damaging infrastructure and introducing harmful chemicals into the water supply. Heavy water use during firefighting can deplete systems, leading to lower pressure and contamination. Heat from fires can melt plastic pipes and water meters, releasing toxic substances such as benzene that can cause immediate health effects such as nausea, headaches and rashes. Smoke and ash can also seep into plumbing systems, exacerbating the problem. Steps to ensure water safety
Follow local warnings: pay attention to water suppliers' and health authorities' messages on water safety.
Chemical tests: Safe water is determined by appropriate tests. Residents should avoid using water until tests confirm it is safe.
Be cautious about testing: Improper water sampling or inadequate testing can result in wasted money and effort. Work with trusted professionals and wait for utility updates.
Replacement and prevention
Restoring safe water can take time as testing may be delayed until affected areas are made safe. Communities that work together and follow expert advice recover more effectively. New guidance published in 2024 now offers detailed steps for water systems to respond to and recover from wildfires, helping to protect communities in the future.
While the challenges are significant, history shows that with proper precautions and collaboration, safe drinking water can be restored. | BGNES
