True, developments of former farmlands are needed to improve the overall growth of farming quality. But, things will not be as environment friendly as thought. Such development can disturb pesticides spread nearly a century ago, hence landing up contaminating nearby water sources. A study by researchers at Dartmouth College concluded.
Thus, the findings signify that communities may need to take additional precautions when the soil at former orchards and farms is disturbed for development or new agricultural uses! Carl Renshaw, a professor of earth sciences, said this in a news release.
Pesticides spread during the early 1900s contained both arsenic and lead. And the problem is that researchers have found these in the top 10 inches of soil. The January-February issue of the Journal of Environmental Quality will publish this result.
