Vista GeoScience has over 20 years’ experience conducting Tier-II landfill gas surveys at Class II/III Solid Waste Facility and SWMUs across the United States. We developed and perfected the tooling and methods required to sample and analyze NMOCs by EPA Method 25C (40-CFR60).  Key staff has more than 30 years’ experience in sampling, soil gas testing, remediation, and laboratory analysis.  Our expertise includes mapping and analysis of stray and fugitive gas in soil gas and ground water.
