The hydraulic conductivity of soil is measured as 2.5×10-2 cm/sec. After an accident, a truck carrying dissolved salt solution releases its contents to the surface. The distance between the spill and a groundwater well is 2600 meters. The groundwater elevation at the spill location is 6.5 meters, and the well location is 5.2 meters. Porosity of soil is 0.3. Travel time of contaminant to the well is most nearly (years):
