Pathogen Pathways − Contamination of water bodies via artificial drainage
2. Specific research objectives addressed in this report
(Refer to “Pathogen Transmission Routes: Farm Animals to Water Bodies; Collins”, 2002)
Objective 3: To determine the existence of pathogen contamination of artificial drainage water
Controlled field experiments were conducted to investigate the movement of Campylobacter, E. Coli, Giardia cysts and Cryptosporidium oocysts from grazed dairy pastures into waterways via sub-surface drainage.
Objective 6: To determine the influence of sequential post grazing rainfall on pathogen contamination of successive drainage events
Follow-up experiments to Objective 3 that investigate the relationships between numbers of Campylobacter, and E. Coli appearing in drainage water and the persistence of viable Campylobacter, and E. Coli organisms in dung with time after dung deposition and successive drainage events.
Objective 9: Contamination of surface runoff under dairying
Follow-up experiments to Objective 3 that investigate the relationships between numbers of Campylobacter, and E. Coli appearing in surface runoff water and the persistence of viable Campylobacter, and E. Coli organisms in dung with time after dung deposition and successive drainage events.
