The effect of sediment redox conditions on the solubility behavior of Fe, Pb, Ni, Ba, and Cu in bottom sediment collected from a produce water discharge site was investigated using kinetics and chemical fractionation procedures. Sediment collected was composited and subsamples incubated in laboratory microcosms under controlled Eh-pH by: Produced water often is permitted for discharge from offshore oil and gas production platforms or shore-side treatment facilities to the territorial seas of many countries. However, there is a limited amount of information available about the chemical composition of produced water (Neff et al, ) and about effects of chronic discharges on Cited by: Effect of Produced-Water Discharge on Bottom Sediment Chemistry. New Orleans, LA: US Department of the Interior, Minerals Management Service, Gulf of Mexico OCS Region,; p. Report No.: MMS 99–Author: Hossein D. Atoufi, David J. Lampert. Kinetics and chemical fractionation procedures were used to quantify the effect of the sediment redox (Eh) condition on the behavior of As, Cd, Cr, and Zn in the bottom sediment collected from a Louisiana coastal site receiving produced water discharge. Sediment samples were incubated in microcosms in which Eh-pH conditions were by:
Upon discharge to the ocean, produced water dilutes rapidly, often by fold or more within m of the discharge. The chemicals of greatest environmental concern in produced water, because their concentrations may be high enough to cause bioaccumulation and toxicity, include aromatic hydrocarbons, some alkylphenols, and a few by: Furthermore, it is notoriously difficult to study effects of the discharges on populations (e.g. of commercial fish stocks) and the structure and function of marine ecosystems. This review shows a wealth of studies on the effects of produced water on individuals of important species, and on the effects of drilling waste on benthic by: initial bulk dilution of for a discharge of produced water with a density of kg per m 3 at a maximum rate of 30, m 3 /day from a cm pipe at 5 m below sea surface, (Hodgins and.

Nitrogen and carbon limitation of denitrification in the bed sediments of an effluent‐dominated stream were investigated by quantifying the effects of nitrate and glucose additions on the rate of sediment N 2 O production. Bed sediment samples were collected from a 30‐km stretch of the South Platte River where up to 95% of the base flow discharge consists of effluent from a Cited by: Produced water remains the largest volume waste stream from oil and gas production offshore. In the North and Norwegian Seas, produced water volumes are projected to increase significantly over the coming decades, as oil reservoirs near depletion. These releases are therefore the focus of continuing environmental concern.
