Health Considerations for Residents Near DU PONT POMONA PLANT
Living near a Toxic Release Inventory (TRI) facility in POMONA, California (91766) means potential exposure to industrial pollutants through air, water, and soil. While not every facility creates immediate health risks, long-term proximity warrants awareness and proactive steps.
Water Testing
Given the water quality score of 8/100 for zip code 91766, we recommend annual water testing for heavy metals, VOCs, and industrial contaminants — especially if you use well water. Testing kits are available through your county health department or certified labs.
Air Quality Monitoring
Monitor daily AQI (Air Quality Index) at airnow.gov, particularly on hot, stagnant days when ground-level pollutants concentrate. If you notice unusual odors or visible emissions from DU PONT POMONA PLANT, report them to California's environmental agency.
When to Consult a Doctor
Speak with your physician if you experience persistent respiratory symptoms (chronic cough, wheezing, shortness of breath), unexplained headaches, skin irritation, or unusual fatigue — particularly if these worsen when you're at home. Mention your proximity to a TRI facility so they can order appropriate screening. Vulnerable populations — children, elderly, pregnant women, and those with asthma — should be especially vigilant.
