The impact of anthropogenic activities on the accumulation heavy metals in water, sediment and fish both Ennore creek Vellar estuary were observed this study. Water sample collected from sampling stations was just only creek. Sediment samples subjected to a total digestion technique (HNO3 – HCl HF conc.) analysed using spectrophotometer. Four elements Cu, Cd, Zn Pb (trace elements) determined. ...

Sinking Creek (HUC 06010103046), in the Watauga watershed of northeast Tennessee, is impaired due to Escherichia coli. To assess how E. coli and other water quality parameters fluctuated during storm events, samples were collected with automated samplers eight storms at two locations: a feeder spring. Turbidity electrical conductivity data loggers deployed creek, dissolved oxygen (DO) was measu...

Dissolved arsenic typically results from chemical weathering of rich sediments and is most often found in oxidized forms surface water. The mobility controlled by its valence state also association with iron oxides minerals, the which are both influenced abiotic biotic processes aqueous environment. In this study, speciation methods were used to measure confirm presence reduced species water Fr...

Many of Alabama's rivers and streams do not meet the Clean Water Act's "swimmable" goal due to fecal contamination. Catoma Creek in Montgomery County has been included on Alabama's Section 303(d) List due to elevated numbers of fecal coliform bacteria and organic enrichment. Both urban and agricultural land uses exist in the watershed. The objectives of this research were to construct a library...

This study examined radiocesium (137Cs) levels in fish from the vicinity of the Department of Energy's Savannah River Site (SRS), a former nuclear weapons production facility in South Carolina. Fish from the Savannah River were sampled above (upstream), along, and below (downstream) the SRS, and from Steel Creek, a tributary that runs through the SRS. There was some off-site contamination of 13...

The cycling of dissolved inorganic carbon (DIC) and the role of tidal marshes in estuarine DIC dynamics were studied in a Virginia tidal freshwater marsh and adjacent estuary. DIC was measured over diurnal cycles in different seasons in a marsh tidal creek and at the junction of the creek with the adjacent Pamunkey River. In the creek, DIC concentrations around high tide were controlled by the ...
