FECAL COLIFORM RELEASE FROM CATTLE FECAL DEPOSITS1

JAWRA Journal of the American Water Resources Association, 1984
ABSTRACT: Cowpies molded to a standard configuration and size were subjected to simulated rainfall, and the fecal coliform counts were determined using the most probable number (MPN) method of enumeration. The standard cowpie deposits were exposed to simulated rainfall once at ages 2 through 100 days.

Intermittent filtration of wastewater—removal of fecal coliforms and fecal streptococci

Water Research, 2002
Removal of fecal coliforms and fecal streptococci was monitored over a period of 13 months in 14 buried pilot scale filters, treating septic tank effluent. The effects of grain size, hydraulic dosing rate and distribution method were investigated. Two different natural sands (sorted sand and unsorted sand) and three different types of light weight ...

Agar Medium for Enumeration of Fecal Coliforms

Journal of Food Science, 1992
ABSTRACTSpread‐inoculated plates of fecal‐coliform agar (FCA) were pre‐incubated 2 hr at 35°C, and then transferred to 44.5°C for 22 hr. Fecal coliforms on FCA produce acids and CO2, which react with bromocresol purple and calcium lactate to form yellow to yellow‐green colonies surrounded by a pale yellow zone.

Coliform-Fecal Coliform Bacterial in Tidal Waters

Journal of the Sanitary Engineering Division, 1968
The fecal coliform-coliform relationship has been examined for several estuaries on Long Island to evaluate proposed fecal coliform standards for shellfish growing waters. The level of fecal coliforms to coliforms was found to vary with source of pollution, level of treatment provided, characteristics of the receiving waters, and precipitation on the ...

Closing the Door on the Fecal Coliform Assay [PDF]

Microbe Magazine, 2006
Since its inception in 1904, the fecal coliform assay has been used to assess the presence of fecal contamination in water and foods. Assays to detect Escherichia coli, a more specific indicator of fecal contamination, were previously not as popular due to the longer time period for detection required (five days) and their complexity.

Spatial and Temporal Dynamics of Fecal Coliform and Associated with Suspended Solids and Water within Five Northern California Estuaries.

Journal of Environmental Quality, 2013
Fecal coliform and associated with suspended solids (SS) and water in five northern California estuaries were studied to document process influences and water quality monitoring biases affecting indicator bacteria concentrations.

Estimation and modeling of direct rapid sand filtration for total fecal coliform removal from secondary clarifier effluents.

Water Science and Technology, 2012
The filtration of fecal coliform from a secondary clarifier effluent was investigated using direct rapid sand filters as tertiary wastewater treatment on a pilot scale.

Exploring Seasonality in Escherichia coli and Fecal Coliform Ratios in Urban Watersheds

, 2014
As regulators in the United States develop plans to mitigate microbial pollution via the design of total maximum daily load (TMDL) plans, historical data sets are often used to establish existing conditions for watersheds. Due to the revision of guidance

Assessing fecal coliform fate and transport in a coastal watershed using HSPF.

Water Science and Technology, 2012
There is increasing concern regarding spread and proliferation of pathogenic microorganisms in watersheds and their impacts on water quality. In agricultural and rural watersheds fecal coliform occurrence, an indicator of pathogenic contamination, is ...

Regrowth of Fecal Coliforms in Class A Biosolids

Water Environment Research, 2006
Eight types of Class A biosolids were tested for fecal coliform (FC) reactivation and/or regrowth at 20, 35, and 50°C for 21 days. Growth of FC did not occur at 20 or 50°C, but it was observed in two samples incubated at 35°C after a lag period of 48 hours. In undigested biosolids, final FC concentration exceeded 10 4 MPN/g, whereas in thermophilically
