Anthropogenic and geogenic factors affecting groundwater arsenic and potential drinking water exposure in the San Luis Valley, Colorado Anthropogenic and geogenic factors affecting groundwater arsenic and potential drinking water exposure in the San Luis Valley, Colorado

Groundwater arsenic is a serious health threat in many regions with limited surface water drinking supplies. In the San Luis Valley, Colorado, USA, where most residents rely on groundwater for drinking water, elevated groundwater arsenic concentrations (≥5 μg/L) were observed in 19.8% of private wells. Many recent studies have leveraged data science methods to estimate the spatial...

Aging of biosolids in fields prolongs the release of biosolid-borne PFAS and promotes the release of select PFCA in water Aging of biosolids in fields prolongs the release of biosolid-borne PFAS and promotes the release of select PFCA in water

Land application of biosolids can introduce PFAS into croplands. Biosolids transported to surface waters through runoff may subsequently release PFAS into aquatic environments. The objective was to evaluate the effects of the aging of biosolids and the presence of sediment on the release of biosolid-borne PFAS to water at the water-sediment interface under anaerobic conditions. Through...

Permeability and compressibility of “seal” sediment overlying the B1 sand gas hydrate reservoir: Hydrate 02 Geo Data Well, Prudhoe Bay unit, Alaska North Slope Permeability and compressibility of “seal” sediment overlying the B1 sand gas hydrate reservoir: Hydrate 02 Geo Data Well, Prudhoe Bay unit, Alaska North Slope

An important element in evaluating the viability of extracting methane from a gas hydrate-bearing reservoir is establishing the effectiveness of the overlying bounding sediment as a seal to prevent gas loss, to enable effective depressurization, and to prevent fluid from entering the reservoir during production. This laboratory study presents results for index properties (e.g., grain...
