The freeze-thaw cycle likely has more influence on infiltration than compost in the first year after <br />construction. Testing methods changed in October, moving from a subsurface test to a surface test. This changed the <br />equation used to calculate saturated hydraulic conductivity and will also make future measurements easier and more <br />accurate. <br /> <br />Qbhf!9!pg!63 <br /> <br />
