3Detecting leaks in natural gas and oil pipelines is an ever increasing problem for the pipeline industry. Precisely locating the leak below ground is of utmost importance to avoid potential large fines and polluting and contaminating the environment. A majority of pipelines across the U.S. and Canada are over 50 years old with some even been installed in the early 1900's. Once a leak is determined to be occurring in the pipeline a decision has to be made as to digging up and replacing the entire pipeline or exactly pinpointing the location of the leak below ground and repairing that particular section. A pipeline leak detection dog can locate the precise location of the leak below ground as the specialized odorant rises to the surface through the leak. This leak detection method saves an enormous amount of time and money.
