Does pasture irrigation increase groundwater contamination?
MADISON, WI, June 14th, 2010 – Concern about microbial contamination of groundwater from foraging dairy cows has increased as spray irrigation practices in New Zealand have increased over the years. Bacteria capable of living in both animals and humans are commonly found in cow manure. Addressing the lack of research on the topic, a team of New Zealand researchers studied the transport of microbes from two spray irrigated dairy pastures into groundwater supplies.
