Is rotenone likely to enter ground water and pollute water supplies?
A. The mobility of rotenone in soil is low to slight. The expected leaching distance of rotenone in soils would be only two cm (less than one inch) in most types of soils. An exception would be in sandy soils where the expected leaching distance is about eight cm (sightly more than three inches). Rotenone is strongly bound to organic matter in soil, so it is unlikely that it would enter ground water, even if it had not degraded. Because of its rapid breakdown, rotenone leaves only temporary residues that would not persist as pollutants of ground water supplies.
