The area falling under Phase II of NAM in Bihar State covers the aquifers in the Ganga stem part and spreads over the Saran, Vaishali, Samastipur and Begusarai located on the northern bank of the Ganges and the eastern parts of the Patna district on the southern bank of the Ganga. A total of 23 blocks have been covered during this phase. The study area spreads over 2678 Sq Kms covering 23 administrative blocks. The area lies between N latitudes 25.851 and 25.491 and E longitudes 84.573 and 86.197 falling in Survey of India toposheet nos 72C/9, 10, 13, 14, 72G/2, 5, 6, 7, 10, 11, 14, 15 and 72K/2, 3. The population density of the study area is 289 person per sq. km. The phase 2 area of Bihar stretches from Saran in west to Begusarai in east covering parts of five districts and 23 blocks. The phase 2 area is traversed by approximately 172 km long stretch of river Ganga forming the axial drainage. The area is characterised by highly fertile alluvial plain. The soil type is loamy to coarse grained. During heavy monsoons, part of the area on the southern bank of the river Ganga gets flooded and remains water logged for months, locally called as tal areas. The study area forms part of the Middle Ganga Plain and physiographic ally it represents a monotonous flat topography. The land surface for the part located on the northern bank of the River Gnaga shows a general slope towards the south-east while for the part located on the southern flank of the Ganges, the general slope is towards north-east. The area is drained by rivers Ganga, Gandak and their tributaries . The west - east flow of the River Ganga forms the axial drainage of the area. The River Ganga forms the levee or upland all along its southern bank. In the south of the natural levee of the Ganga, there is a vast stretch of backwaters known as the Tal lands. The west to east flowing Ganga River forms the master drainage of the area. River Gandak from north joins the River Ganga in the western part of the study area at Sonepur near Patna. The part of the study area falling in Vaishali and samastipur district falls in the doab between the Ganga and the Burhi–Gandak. The other rivers in the are are the Baya, Balan, Jamuari etc flowing in NW-SE direction. Marshes and swamps locally known as Chaurs are common in the area. The area forms a part of the Gangetic plain underlain by immensely thick alluvial deposits comprising sediments (sand, gravel and clay) of Quaternary age deposited unconformably over the Precambrian basement. The alluvial deposits are characteristically divided into the Older and the Younger Alluvium.
