Andhra Pradesh is the fourth largest State in India covering geographical area of 2,75, 068 sq.km. Physiographically, Andhra Pradesh State can be divided into three distinct zones, viz., Coastal Plains, Eastern Ghats and Western Pedeplains. The landforms, altitude and drainage pattern are different in each zone. The first two units stretch from Northeast to Southwest in a narrow strip while the western pedeplains occupy rest of the area. During the year 2014-15, 26 Dug wells and 16 Piezometers are abandoned and 44 new monitoring wells (43 Dug wells and 1 Piezometers) are established forming a network of 881wells including 772 Dug wells and 109 Piezometers (as on 31-3-2015). The dug wells tapping unconfined aquifers are used for domestic purpose by local populace. Some of these are community wells and the rest belong to individuals. The piezometers tapping unconfined and confined aquifers are constructed under various projects and exploration programmes by the department. The coastal plains stretch from Kalingapatnam (Srikakulam district) in the north to Pulicot (Nellore district) in the south along a narrow strip, which broadens in the middle along Godavari - Krishna deltas (up to 80 sq.km). The altitude of coastal plains ranges from sea level at the coast to 150 - 200 m amsl on the west. The Eastern Ghats follow the Coastal Plains stretching closely from one end to the other except in area between the Godavari and Krishna rivers. The hill ranges trend in NE - SW direction in the north and in N-S direction in the south and attain elevation of 600 to 1200 m amsl. A major part of the State covering part of Rayalaseema region (Kurnool and Anantapur districts), fall in this category of physiographic unit. The pedeplains show rolling topography with flat to undulating tracts. This plateau in the interior of the State extends largely between elevation of 150 to 600 m amsl except at places where it is overlain by Basaltic Lava flows, the elevation of which ranges from 600 to 900 m amsl. The State is drained by 40 major and minor rivers. The important rivers are Godavari, Krishna, Pennar, Palar, Vamsadhara, and Nagavalli. Godavari and Krishna rivers and their tributaries drain the northern and central part and Pennar river drains the southern part of the state before confluence in to Bay of Bengal. There are 3 major basins and 11 medium river basins in the state. The normal annual rainfall is 952mm. Season-wise normal rainfall is 555 mm, 285 mm, 9.8 mm and 96.3mm in monsoon (June-Sept), post-monsoon (Oct-Dec), winter (Jan-Feb) and summer (March-May) respectively, 58% of annual rainfall occur in SW monsoon, 30% in north-east and 12% in non-monsoon seasons. Annual normal rainfall ranges from 574 mm in Anantapur district to 1166 mm in Srikakulam district. The mean annual rainfall during 2014 is 741 mm. Season-wise rainfall is 441.5 mm, 194.8 mm, 1.5 mm and 102.7 mm in monsoon (June-Sept), post-monsoon (Oct-Dec), winter (Jan-Feb) and summer (March-May) respectively, contributing 60% of annual rainfall in SW monsoon, 26% in north-east and 14% in non-monsoon seasons. The annual (2014) rainfall ranges from 434 mm in Cuddapah district (deficit by 40%) to 1268 mm (excess by 9%) in Srikakulam district. Annual rainfall was deficit by 22%. Monthly mean rainfall ranges from 0.5 mm in January to 148.6 mm in October. A wide variety of geological formations occur in Andhra Pradesh, ranging from the oldest Archaean crystalline rocks to Recent alluvium. Major part of the State is underlain by gneissic complex with a structural fill of sedimentary rocks and basin-fill of meta-sedimentary rocks. The gneissic complex is overlain by basaltic lava flows in the northwestern part and is intruded by several younger rocks – granites, dolerites, pegmatites, etc. Ground Water Regime Monitoring as lithounits, Hydrogeologically, are classified into three groups, namely- i) Consolidated formations ii) Semi-consolidated formations and iii) Unconsolidated formations. Depth to water level- MAY, 2014- Water levels vary between -0.09(West Godavari district) and 23.78 m.bgl (Prakasham district). Depth to water level of 0 to 10 m bgl is more prevalent in 82% of wells. Shallow water levels of less than 2 m bgl are noticed in very small areas in Coastal Region and in Anantpur and Kurnool districts of Rayalaseema Region in 15.92% of wells. Water level range of 2 to 5 m bgl is observed mostly in Coastal Region and as small isolated areas in Rayalaseema Region in 45.82% of wells. 5 to 10 m bgl range is observed as major parts in Nellore and Prakasham districts of Coastal area and Rayalaseema Region in 30.41% of wells. Depth to water level varying between 10 and 20 m bgl (7.18% of wells) is observed as small isolated patches in coastal region except Vizianagaram, East Godavari and Srikakulam districts and in Rayalaseema Region. It is also observed as major parts in Chittoor district. Deeper water levels of 20 to 40 m bgl (0.65% of wells) are noticed as small patches in Prakasham, Visakhapatnam and Guntur districts in Coastal Region and in Chittoor and Kadapa districts in Rayalaseema Region. Depth to water level - November, 2014- Depth to water level of 0 - 10 m bgl is predominant in the state. Water levels vary between -0.05 m.bgl (Kurnool district) and 27.85 m.bgl (Prakasham district). Shallow water level zone, less than 2 m bgl, spread along the coast and as small isolated patches in Rayalseema region representing 45.2% of wells. 2 to 5 m bgl range is observed all the districts in 33.96 % of wells. Water levels varying between 5 and 10 m bgl are registered in major parts `of Anantpur, Nellore, Prakasham and YSR Kadapa districts and as small isolated areas in coastal region covering 18.98% of wells. Water level ranging 10 and 20 m bgl is noticed mostly in Rayalseema region in 6.62% of wells. Deeper water levels of 20 and 40 m bgl are observed in parts of YSR Kadapa, Prakasham and West Godavari districts representing 0.25% of wells. Fluctuation in November 2014 with reference to May 2014- An analysis of data of 730 wells reveals that water level rise is recorded in 74.38% of wells (543), fall is recorded in 20.95% of wells (153), while in the rest, 4.67% of wells (34) no fluctuation is recorded. Rise of less than 2 m is recorded in 48.9% of wells, 2-4 m in 18.63% of wells and more than 4 m is recorded in 6.85% of wells. Fall of less than 2 m is recorded in 17.67% of wells 2-4 m in 1.78% and more than 4 m is registered in 1.51% of wells. Rise of 4m is registered maximum in Kurnool district (21.43% of wells) while fall of 4m is observed maximum in Anantapur district (7.89%) wells. Ground Water Quality- Monitored 617 ground water monitoring wells in Andhra Pradesh to assess the quality of shallow ground waterduring May, 2014. In general pH is in the range of 6.8 to 9.3. Electrical conductivity is beyond 3000 micromhos/cm in 15.6% of the samples. In general, it is in the range of 750-3000 micromhos/cm. Alkalinity exceeds BIS limit of 600 mg/L in 72 samples. Sodium is in the range of 0.2 - 2387 mg/L. Potassium is in the range of traces to 650 mg/L. In general, it is in the range of 3 to 25 mg/L. Only 4.4% of the samples have chloride concentration beyond BIS permissible limit. In general, it is in the range of 50 to 500 mg/L. Sulphate exceeds the BIS permissible limit of 400 mg/L in 3.1% of the samples. In general, it is in the range of 5 to 50 mg/L. Fluoride exceeds the BIS permissible limit of 1.5 mg/L in 9.2% of the samples. In general it is in the range of 0.3 to 1.0 mg/L. Majority of the wells in the state fall in water samples are falling in C2S1 class and followed by C3S1, C3S2 C3S3, C4S4, C1S1, C4S3, C4S2 and C2S2 classes. Dominant Water types of the state are Na-Cl, Na-HCO3, Na-Ca-Cl-HCO3 and Na-Mg-HCO3 type. Most of the samples are suitable for livestock and poultry consumption. Highest Electrical Conductivity (12040 S/cm) found at Guttalaumadivrm of Prakasam district, mostly saline water intrusion. Highest Hardness (2500 mg/L) found at Marteru of West Godavari district. Highest Chloride (3226 mg/L) found at Marteru of West Godavari district, and also indicative of Saline water intrusion. Highest Sulphate (1286 mg/L) found at Gulyam-DW of Kurnool district. Highest Nitrate (1095 mg/L) found at Guttalaumadivrm of Prakasam district. Highest Fluoride (5.4 mg/L) found at Sitapalli of East Godavari district.
