Soil Methane and Combustible Gas Concentrations from Oil-Gas Well Pads in Utah, U.S.A. Soil gas methane and combustible gas concentrations collected from oil and gas well pad locations in Utah. Soil gas samples were measured on site and/or collected for later analysis as described in supporting documentation. Multiple sample locations around well head and depths within the soil profile are available for select sites. Supporting documents provide information of sample collection protocol and data quality assurance.

The model is optimized for roadway projects but in theory can be applied to a broad range of development types. SELDM is a statistically-based empirical model pre-populated with much of the data required to successfully run the application (Granato, 2013). The model uses Monte Carlo methods (as opposed to deterministic methods) to generate a wide range of precipitation events and stormwater discharges coupled with water-quality constituent concentrations and loads from the upstream...
