“…The basin lies in five physiographic provinces (Parker and others, 1964) and three different ecoregions (Omernik, 1986). In the southern part of the basin, the Coastal Plain physiographic province is characterized by nearly flat topography and thick, sandy-loam soils.…”

“…The bedrock is a moderate to poor aquifer and is relatively unreactive chemically (Parker and others, 1964). The detrital fraction of these sedimentary rocks consists primarily of quartz grains (78 percent) and fragments of metamorphic rocks (16 percent) (Ethridge, 1977).…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
