Health Considerations for Residents Near U.S. DEPARTMENT OF DEFENSE SPECIAL PROCESS LAB

Living near a Toxic Release Inventory (TRI) facility in LARGO-KETTERING, Maryland (20775) 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 20775, 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

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.
