Evaluating mobilization and transport of arsenic in sediments and groundwaters of Aquia aquifer, Maryland, USA.
Groundwater and sediment samples were collected along a flow path in the Aquia aquifer (Paleocene), Maryland in order to examine and study the factors influencing "evolution" of arsenic (As) in these groundwaters. The Aquia crops out near Washington, DC, where it is unconfined, and extends approximately 90 km down dip to the south and east towards and beneath the Chesapeake Bay. The studied flo...
متن کاملImpact of artificial recharge on dissolved noble gases in groundwater in California.
Dissolved noble gas concentrations in groundwater can provide valuable information on recharge temperatures and enable 3H-3He age-dating with the use of physically based interpretive models. This study presents a large (905 samples) data set of dissolved noble gas concentrations from drinking water supply wells throughout California, representing a range of physiographic, climatic, and water ma...

متن کاملNoble gases and stable isotopes in a shallow aquifer in southern Michigan: Implications for noble gas paleotemperature reconstructions for cool climates
[1] Noble gas data from the Glacial Drift, the shallowest aquifer in southern Michigan confirm findings by Ma et al. (2004) that modern noble gas temperatures (NGTs) are systematically below the current mean annual air temperature (MAAT) which, in turn, is similar to the ground temperature of these recharge waters. By tracking noble gas concentrations as well as stable isotope ratios through an...
