Surveys & Analysis, Inc. is a national contractor specializing exclusively in natural gas leak surveys. For more than 85 years of continuous operation. We’ve helped gas distribution and transmission operators meet — and often set — the standards of the leak survey industry. S&A is a turnkey leak survey solution: qualified surveyors, calibrated instrumentation, scheduling, execution, QA/QC, and audit-ready reporting under one roof.
Specialization Is the Point
Leak survey is our passion and our only focus. We understand compliance schedules and the regulatory requirements behind them — the leakage survey intervals of 49 CFR §192.723 for distribution systems, §192.706 for transmission lines, and the elevated expectations of PHMSA’s Leak Detection and Repair rule. Just as important, we understand that how and when we survey affects your maintenance schedules, repair crews, planning, and budgets. Our job is to make your compliance calendar boring — in the best possible way.
Supplementing or Outsourcing? Either Way, We’re the Call.
Whether your company is benchmarking your current contractor, supplementing an in house survey workforce, or outsourcing leak survey completely, partnering with the right firm is critical. Communication, coordination, cooperation — S&A has made a science of it, with the experience and expertise to make the transition smooth and the results defensible.
Our History
S&A’s roots stem back to the [1930s]. Our founder established Vegetation Surveys, Inc. in Northborough, Massachusetts, pioneering vegetation-indication leak survey — one of the earliest systematic methods of finding underground gas leaks. In 1967, the company became Surveys & Analysis, Inc. to reflect modern instrumented survey techniques. Today, headquartered in Shrewsbury, Massachusetts, S&A has provided leak survey services to gas utilities in every state in the continental United States and has inspected the gas facilities of more than 45 million homes and businesses.
