🏭Industrial Pollution Exposure

10.2th percentile

Property Pollution Ranking

High

Higher pollution than 90% of Houston homes

Compares pollution within 2mi against 10,000 Houston properties. Lower percentiles = higher pollution.

Industrial Pollution Nearby (10 Years)

7.75 millionlbs

Extremely High

1187.3x more than typical Houston property

≈ 387 dump trucks of chemicals within 2 miles

Air Pollution (10 Years)

7.73 millionlbs

Extremely High

1602.1x more than typical Houston property

Includes fugitive emissions (leaks) and stack emissions (smokestacks).

Water Pollution (10 Years)

20 thousandlbs

Extremely High

Discharges to bayous, streams, and drainage systems.

Facilities Nearby

Industrial facilities within 2 miles

💡

Why It Matters: High chemical activity nearby can indicate industrial zones, truck traffic, or potential odor and noise issues. These factors may affect air quality, long-term property desirability, and neighborhood character. This data helps you understand the industrial footprint around your property.
