Key Personnel

Beacon Environmental has earned an enviable reputation for providing accurate, reproducible data. Beacon Environmental's passive soil gas (PSG) samplers are extremely easy to use and offer the ability to sample in the subsurface or directly on the ground surface, with both field applications providing highly accurate results.

The principals of BEACON have many years of experience in characterizing sites for organic contaminants using innovative soil-gas sampling technologies. BEACON was founded in 1999 by Mr. Harry O'Neill, who is the company president and has managed and reviewed data from 1,000s of soil gas surveys. Prior to forming BEACON, Mr. O’Neill managed the soil-gas sampling program for Quadrel Services, Inc., an innovative company that lead the acceptance of passive soil-gas sampling at the national and international level.

Mr. Steve Thornley is the company's Laboratory Director, who is responsible for sample analyses and ensures that all project samples are analyzed and reported following the highest level of quality assurance procedures in the industry. Mr. Thornley has analyzed and reported data from more than 50,000 soil-gas samples and follows established analytical procedures that allow BEACON to provide accurate, reliable, and defensible data.

Harry O'Neill was selected as the lead author to write the ASTM Standard for Passive Soil Gas Sampling that was approved December 1, 2011.
