Key Personnel

Beacon Environmental has earned an enviable reputation for providing accurate, reproducible data and the team has developed easy to use samplers and techniques for sampling soil gas or air that are provided through BeSure Sample Collection Kits.  The professionals at Beacon have extensive knowledge of adsorbent selection and analytical techniques to sample a broad range of VOCs and SVOCs in soil gas, ambient air, or indoor air, whether characerizing sites, assessing vapor intrusion risks, or monitoring emissions in the air.

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 projects. Prior to forming BEACON, Mr. O’Neill managed the soil-gas sampling program for Quadrel Services, Inc., an innovative company that led the acceptance of passive soil-gas sampling at the national and international level.

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.
