Health Considerations for Residents Near NORTHROP GRUMMAN SYSTEMS CORP
Living near a Toxic Release Inventory (TRI) facility in LINTHICUM HEIGHTS, Maryland (21090) 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
Even with acceptable municipal water scores, homes near industrial sites should test annually for contaminants that may leach through groundwater. This is especially important for homes built before 1990 or those on well water in the 21090 area. Testing kits are available through your county health department or certified labs.

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.
