of sulfate in groundwater is lower in the eastern area than in the western area of the basin, and is lower in the northern area than in the southern area; the soluble components in Cretaceous strata are dominated by sulfate existent in the forms of gypsum and mirabilite; the sulfate in ...
As the main anion of groundwater, the content of sulfate affects the drinking water safety and ecological security directly. In recent years, with the acceleration of industrialization and urbanization development, the problem of sulfate pollution in water environments is becoming more and more serious...

The sources of sulfate and geochemical processes controlling ground-water composition were evaluated in this area. Water was sampled from thirty-three wells in parts of Marion, Sumter, and Citrus Counties, within the Southwest Florida Water Management District; these included at least a shallow and...

Although multiple mechanisms for paradoxical (i.e., aerobic) CH4production have been proposed, the degree to which these are active in freshwater lakes remains unknown. Initial studies suggested that CH4production under oxygenated conditions could occur in anoxic microsites present in the water column...
The summertime haze transported from the Gulf Coast northward in maritime tropical air masses is partially formed from emissions in the midwestern and northeastern United States. Several cases are documented in which sulfate particulates, formed from emissions in the Midwest and Northeast, traveled to ...
EPA and EPRI studies on the effects of high levels of atmospheric sulfates reflect the situation of the early 1970's in the Northeast. Emissions, deposition, and transportation; ground-level fluxes; soil-sulfur reactions and river removal; and cycle balance are examined. The health and welfare ...
