Release of Sediment-Bound Fecal Coliforms by Dredging1

Release of sediment-bound fecal coliforms by dredging.

Fecal coliform concentrations increased significantly (F test) in the immediate vicinity of a maintenance dredging operation in the Mississippi River navigation channel. Increased counts were attributed to the disturbance and relocation of bottom sediments by dredging and a concomitant release of sediment-bound fecal coliforms.

Rainfall-induced release of fecal coliforms and other manure constituents: comparison and modeling.

Modeling release of fecal coliforms is an important component of fate and transport simulations related to environmental water quality. Manure constituents other than fecal coliforms may serve as natural tracers of fecal contamination provided that their release from manure to runoff is similar to the fecal coliform release. The objectives of this work were to compare release of fecal coliforms...

Prediction of runoff and sediment from agricultural watersheds by a mathematical model. 3 sediment -bound and soluble phosphorus loadings.

Fecal Coliforms and Fecal Streptococci Contamination of Traditional Ice Cream in Tabriz

Most of present traditional ice cream from hygienic quality has non-conforming with extant standards. Pasteurization of primary ice cream mixture with sufficient thermal processing increase hygienic quality level and causes control of primary infection. Origins of infection for traditional ice cream consist of: use of infected primary materials (milk or cream) or non-pasteurization of them. Stu...

Removal efficiency of nitrate, phosphate, fecal and total coliforms by horizontal subsurface flow-constructed wetland from domestic wastewater

Background: Constructed wetlands are systems designed based on the utilization of natural processes, including vegetation, soil, and their associated microbial assemblage to assist in treating different types of wastewater. Methods: Two local Appalachian plants (Louis latifolia and Phragmites australis) were planted into smallscale constructed wetlands to treat domestic wastewater in the North ...
