Beach fecal coliforms

Canadian Journal of Civil Engineering, 1984
A combination of the STORM runoff model and a two-dimensional dynamic lake type model successfully reproduced the fecal coliform levels of an urban beach on a lake in the Ottawa River. The elevated fecal coliform levels were associated with rainfall events and runoff from two large catchments upstream of the beach.

Coliforms, fecal coliforms, and fecal streptococci as indicators of water pollution

Water, Air, and Soil Pollution, 1973
The presence and survival of coliforms, fecal coliforms, and fecal streptococci were studied in sewage treatment plants, heavily polluted rivers, a lake, and other drinking water sources. In all cases the fecal streptococci were generally more resistant to the natural water environment and to purification processes than the other indicator organisms ...

REGROWTH OF FECAL COLIFORMS

Journal AWWA, 1969
Nonfecal coliforms often undergo regrowth after discharge into a stream. A California team investigates whether fecal coliforms follow suit.

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.

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 ...

Regrowth of coliforms and fecal coliforms in chlorinated wastewater effluent

Water Research, 1973
Abstract Observations made both in the field in chlorinated effluent, and in laboratory experiments show that coliforms and fecal coliforms are capable of regrowth in chlorinated wastewater. Under field conditions regrowth of coliforms in chlorinated effluent held in a storage reservoir for about 3 days appeared inversely correlated to: (1) The ...

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 ...

Extended Acid Digestion for Inactivation of Fecal Coliforms

Water Environment Research, 2006
The objective of this research was to establish a correlation between inactivation of fecal coliforms caused by organic acids in their un‐ionized form in batch acid digesters and semicontinuously fed acid digesters at both mesophilic (38°C) and low‐mesophilic (24°C) temperatures. Batch acid digesters achieved a U.S.
