This powerpoint presentation begins by presenting a brief overview of indicators of fecal contamination of groundwater. A study is presented of survival rates of F-RNA coliphages and assessment of exposure risk in the New River water in California's Imperial Valley. Materials and methods included: sample collection;
detection of male specific
coliphages;
detection of F-RNA
coliphages by genotyping; and,
survival and risk
assessment. Topics covered include: hybridization and oligonucleotide
probe selection; dot-blot hybridization; F-RNA coliphage survival; and, risk of infection assessment. Study conclusions indicate: natural condition showed adequate
attenuation of microorganisms; variation was observed in the survival of
different F-RNA strains of the four genogroups; coliphages could be better suited as models for
human pathogens and can be used to estimate
the risk of infection; and, genotyping by hybridization and DAL method
used for this study are reliable tools for
detecting the microbial pollutants and their
sources of origin in water. Includes tables, figures.
