NRI/AFRI 2011 Water and Watershed and Agricultural Water Science Programs Project Directors Meeting
On February 2, 2011 the AFRI Water and Watershed and Agricultural Water Science awardees met jointly to present their project progress, discuss new topics, and share new ideas. The all-day meeting consisted of two sessions of oral presentations and poster sessions. The meeting served as a forum for project directors to communicate with each other, share information, resources, and initiate the development of new collaborations.
Here are some of the highlights from the meeting:
- Increasing the residence time of wastewater in lagoons may be economica,l feasible, and efficient practice to degrade hormone and antibiotic contaminants into the environment.
- Concentrations of indicator organisms (E. coli and Enterococci) in runoff water are poorly correlated with concentrations of pathogens.
- A passive surface water flux meter is being developed and validated for a low-cost and effective way to monitor propagation of hormones as well as other compounds through a watershed.
- Some agricultural soils on the islands of Hawaii can act as reservoirs of pathogens due to the high levels of particulate organic matter in the soils. Salmonella is less sensitive to sunlight than Enterococci.
- Incorporation of manure applied to corn land did not significantly affect E. coli levels in event runoff.
