Here we investigate six permitted discharges on three neighboring tributary systems in Wyoming. During —16, we evaluated radium activities of the permitted discharges and the potential for radium accumulation in associated stream sediments. Sediment as deep as 30 cm near the point of discharge had radium activities elevated above background. X-ray diffraction and targeted sequential extraction of radium in sediments indicate that radium is likely coprecipitated with carbonate and, to a lesser extent, sulfate minerals. PHREEQC modeling predicts radium coprecipitation with aragonite and barite, but over-estimates the latter compared to observations of downstream sediment, where carbonate predominates.

Carbon capture and storage CCS is broadly recognised as having the potential to play a key role in meeting climate change targets, delivering low carbon heat and power, decarbonising industry and, more recently, its ability to facilitate the net removal of CO 2 from the atmosphere. However, despite this broad consensus and its technical maturity, CCS has not yet been deployed on a scale commensurate with the ambitions articulated a decade ago.
to determine if waterbodies are supporting their beneficial uses. The Montana Bureau of Mining and Geology monitors long-term eastern Montana, thick shale formations near the surface make To date these are the For example, water purveyors that prevent pollutants from entering water supply.
CCS can directly reduce industrial CO 2 emissions and is essential for the retention of CO 2 extracted from the atmosphere. To be effective as a climate change mitigation tool, CO 2 must be securely retained for 10, years 10 ka with a leakage rate of below 0. Migration of CO 2 back to the atmosphere via leakage through geological faults is a potential high impact risk to CO 2 storage integrity. U-Th dating of travertine deposits shows leakage varies along a single fault and that individual seeps have lifespans of up to ka.
Hence, even this natural geological storage site, which would be deemed to be of too high risk to be selected for engineered geologic storage, is adequate to store CO 2 for climate mitigation purposes. The integrity of engineered subsurface geological carbon dioxide CO 2 reservoirs is governed by a range of geological, geochemical, and geotechnical factors. Faults and naturally occurring or induced fracture networks can form preferential fluid pathways that bypass impermeable caprock seals and may lead to rapid migration of CO 2 from the subsurface reservoir to shallow aquifers or the atmosphere 1 , 2 , 3 , 4.
