Perhaps there is water coming out, and mud in the vicinity at all times of year?

Where are you located? We had a problem where we were unable to locate a leak in our fire line. Our building is about 2 million square feet over 147 acres. Fire lines were fed from 2 municipalities. We had a company come in with electronic listening devices and they located the leak within 2 feet. He also located several shut off valves with problems needing attention. The fire line is located under about 18 to 24 inches of blacktop and crushed stone. I was impressed with his results.

We are in the New York City area. If you contact me I can give you the name of the company if needed or you could probably locate someone within your area.

i've put mercaptain (natural gas ordorizer) in lines then just follow the smell. Don't do this in an area where they is also natural gas with the same odor because people will think its a gas leak.

Hexafloural Shulphide is used as a tracer too.

They make a biodegradable bright green dye that will allow you to find leaks in araes always wet.

The ultrasonic noise detection is great.
