Abstract :
Soil subsidence which is caused by soil piping is the gradual sinking of the earth’s surface owing to subsurface movement of the earth materials. This research studied the physico-chemical analysis of uncontrolled soil pipes leading to soil subsidence in Anambra state. The study was carried out in three locations: Awka site, 1 (6.22320N and 7.08240E), Awka site 2, (6.22200N and 7.08190E), Agulu, (6.3401N and 7.1233E). A total of 24 soil samples were investigated, which include 15 samples, in and around the soil subsidence location and 9 samples, 20m away from the soil subsidence location. The parameters examined include pH, Electrical Conductivity (EC), Total Dissolved Solid (TDS), Organic Carbon, Organic Matter and Soil Texture. The pH values ranges from 4.8 at the piping zone to 6.8 mostly at the non-piping zone, indicating acidity in the soil, the value of electrical conductivity ranges from 2.21 – 7.21?S/cm. The areas also show very poor organic content of 2.43 at the piping zone indicating that the soil has been heavily drained soil and the soil texture analysed at the piping regions showed a very poor clay content of 14 to 19% indicating dispersive processes in the soil.
