Leak Detection Outdoors

Larger underground pipelines across the state are clearly marked with signs so you can be aware they're in the area. The lines are designed, installed, tested and maintained to meet every federal, state, and industry code and regulation. And they're constantly monitored and inspected to locate and fix potential problems in advance.

But considering there's more than 9,000 miles of line in place across the state, it is best to be prepared for the occasional, but rare, leak.

Follow Your Senses
If you're near a natural gas pipeline, these tips can help you spot a natural gas leak outdoors:

Use Your Eyes
If you SEE dirt or water blowing into the air, or notice standing water continuously bubbling, there may be a leak. You also can look for discolored vegetation (like brown patches in a green field), or you might notice dry spots in a moist field.

Use Your Nose
If you SMELL an odor that has the distinct scent of sulfur or rotten eggs, there may be a leak.

Use Your Ears
If you HEAR a loud roaring or high-pitched hissing sound, there may be a leak.

Take Action
If you detect a leak outdoors, do the following:

  • Leave the area immediately.
  • Call Texas Gas Service - 1-800-959-LEAK(5325).

Your local emergency authorities know what to do in this situation. We work with local authorities to minimize and eliminate any danger. It's our job to find and terminate the leak as quickly as possible.
