Where did it all go, Blanch?

"'We found that the economic value of wastewater used for irrigation represents a significant monetary benefit to both society and these water users,' says Dr. Chris Scott, the IWMI researcher leading this project."

From the International Water Management Institute web site.

At least some of Mexico's agriculture irrigation "serves as a defacto water treatment facility with significant retention of contaminants."

A statement of the benefits (with one trifling concern, public health) of our federal government's free-trade globalization, agriculture sector:

"In developing countries, wastewater irrigation has the potential to offer equally important advantages and dangers to people's health and the environment. Whatever the perceptions, the simple truth is: in these countries, wastewater irrigation is a fact of life. IWMI's research is looking at the health and environmental impacts of this practice - to help planners set effective wastewater irrigation policies."
