http://ecoursesonline.iasri.res.in/mod/page/view.php?id=3210 In hydrology, bound water, is an extremely thin layer of water surrounding mineral surfaces. Water molecules have a strong electrical polarity, meaning that there is a very strong positive charge on one side of the molecule and a strong negative charge on the other. This causes the water molecules to bond to each other and to other charged surfaces, such as soil minerals. Clay in particular has a high ability to bond with water molecules.
