USGS : Well, no, that would break the trust with the gas companies that allowed us access.
USGS : Because we were told so.
USGS : The US Department of Energy in collaboration with the gas companies.
USGS : No, but pressure from higher-ups at USGS forced our hand .
To summarize: The oil and gas industry chose specific wells, in which USGS researchers unsurprisingly measured low radon concentrations and were then pressured by the oil and gas industry to publish these preliminary findings, under the USGS imprimatur. It appears the USGS has been corrupted by the oil and gas industry.
