Factors controlling variability in nearshore fecal pollution: the effects of mortality.
A suite of physical-biological models was used to explore the importance of mortality and fluid dynamics in controlling concentrations of fecal indicator bacteria (FIB) at Huntington Beach, CA. An advection-diffusion (AD) model provided a baseline to assess improvements in model skill with the inclusion of mortality. Six forms of mortality were modeled. All mortality models performed better tha...
متن کاملPepper mild mottle virus as an indicator of fecal pollution.
Accurate indicators of fecal pollution are needed in order to minimize public health risks associated with wastewater contamination in recreational waters. However, the bacterial indicators currently used for monitoring water quality do not correlate with the presence of pathogens. Here we demonstrate that the plant pathogen Pepper mild mottle virus (PMMoV) is widespread and abundant in wastewa...
متن کاملFungi Occurrence Assessment in Drinking Water Distribution Systems and Its Relationship with Fecal Indicator Bacteria
Introduction: As recommended by World Health Organization, consumption of the fungal contaminated water does not cause to serious infection, but may lead to healthy or aesthetic problems. The aim of this research was to assess the occurrence of fungi in water and its relationship with fecal indicator bacteria. Materials and Methods: 110 water samples were collected from different location of w...
متن کاملEcological control of fecal indicator bacteria in an urban stream.
Fecal indicator bacteria (FIB) have long been used as a marker of fecal pollution in surface waters subject to point source and non-point source discharges of treated or untreated human waste. In this paper, we set out to determine the source(s) of elevated FIB concentrations in Cucamonga Creek, a concrete-lined urban stream in southern California. Flow in the creek consists primarily of treate...
متن کاملAddressing uncertainty in fecal indicator bacteria dark inactivation rates.
Assessing the potential threat of fecal contamination in surface water often depends on model forecasts which assume that fecal indicator bacteria (FIB, a proxy for the concentration of pathogens found in fecal contamination from warm-blooded animals) are lost or removed from the water column at a certain rate (often referred to as an "inactivation" rate). In efforts to reduce human health risk...
