Survival rate of pathogenic bacteria and viruses in groundwater

Abstract

The results of an analytical review of publications on the process of inactivation of pathogenic microorganisms in groundwater are considered. The process of inactivation is described by a mathematical model based on an exponential dependence. The values of the inactivation rate factor for a number of pathogenic microorganisms are given. Recommendations are given regarding formulas for determining the dependence of the inactivation rate factor of bacteria and viruses on water temperature.

Processes in Pathogenic Biocolloidal Contaminants Transport in Saturated and Unsaturated Porous Media: A Review

“…Waterborne viruses include enteroviruses, coxsackievirus, echovirus, rotavirus, norovirus and hepatitis A and B. Bacteria of concern are chiefly enteropathogenic E. coli, salmonella and Shigella spp., Campylobacter jejuni and Aeromonas hydrophila, among others. The main protozoa that have been transmitted by groundwater are Cryptosporidium parvum and Giardia lamblia (Macler and Merkle 2000) Bacteria are microscopic (1-6 μm in size) unicellular organisms with a nucleus; viruses are submicroscopic (20-120 nm in size) biological agents consisting of molecules of nucleic acids and a protein envelope (Nevecherya et al 2005).The contamination of subsurface water by migrating pathogenic bacteria and viruses has caused large outbreaks of waterborne diseases (Pekdeger et al 1985;Stevik et al 2004). The most important pathogenic germs which might possible be transported on the subsurface water path are the bacteria Salmonella sp., Shigella sp., Yersinia enterocolitica, Yersinia pseudotuberculosis Leptospira, Dyspepsia coli, enterotoxigenic E. coli, Vibrio sp., Legionella sp., and the viruses infectious hepatitis virus, polio virus, coxsackie viruses, rotavirus, norwalk-like virus (Pekdeger et al 1985).…”

Contamination of water resources by pathogenic bacteria

“…Controlling groundwater pathogen contamination has recently been emphasized in many countries, as pathogens can survive up to 400 days depending on the soil temperature (Nevecherya et al [2005]; Filip and Demnerova [2009]). For example, identifying sources of groundwater pathogen contamination has received significant attention in France (Grisey et al [2010]).…”

Burial grounds’ impact on groundwater and public health: an overview

“…High‐organic matter contents may increase the survival of bacteria in soil and compete with microorganisms for adsorption sites in the soil matrix (Nevecherya et al . ). Also, the presence of organic layers and iron oxides, as well as the ionic strength of the decomposition products seepage, increases the microbial retention, but these layers may collapse due to seepage percolation (Üçisik & Rushbrook ).…”
