If there are septic system limitations, the property use may not be able to be altered beyond existing use and size. In particular cases it may even make a lot undevelopable. 2011-01-13 Similar comparisons were made with the leaching equation of Rousselle (1913) and Levin (1964). The new equation gives good agreement with the observed data, whereas the Rousselle-Levin equation generally overestimates the mean displacement of nitrate. Methods of applying the equations to field situations are discussed.
