*4.5.2 Hydrogeological cross section B-B*0

Hydrogeological cross section B-B<sup>0</sup> (**Figure 12**) represents data from six exploratory wells with a depth of cross section ranging from 180 m bgl to 200 m bgl for 163 km in the W-E direction in the southern part of the district. The thickness of the Aquifer-I is almost uniform along the section line, whereas Aquifer II is having more thickness in the western part up to Sawargaon after which it starts decreasing till Rahudin central-eastern parts. The maximum thickness of Aquifer – II and the maximum number of fractures encountered are observed at Loni in the central part of the section. At Kalkhode, the least number of fractures (1) is encountered, whereas at all other locations, 2 fractures are encountered at various depths. The water levels of Aquifer-I and Aquifer-II have also been depicted in the section and a close observation of the water level indicates that the water table of Aquifer-II is below the water level of Aquifer-I. The water level at Sawargaon in Aquifer-I during the pre-monsoon season was recorded as 7.60 m bgl, whereas in Aquifer-II it was recorded as 13.56 m bgl.

#### *4.5.3 Hydrogeological cross section C-C*0

Hydrogeological cross section C-C<sup>0</sup> (**Figure 13**) represents data from six exploratory wells with the depth of cross section varying from 190 m bgl to 203 m bgl for 126 km WE direction in the northern part. The thickness of the Aquifer-I and Aquifer–II is less in the western part from Khadakmal to Bhaur, whereas in the eastern part of the section line, both the aquifers are having more thickness from Bhaur to Dapure. At Dapure, a maximum number of fractures are encountered with the discharge/yield of 3.17 lps and at Bhaur, the least number of fractures (1) is encountered with a discharge of 0.14 lps, whereas at all other locations, two fractures are encountered at various depths.

#### *4.5.4 Hydrogeological cross section D-D*<sup>0</sup>

Hydrogeological cross section D-D<sup>0</sup> (**Figure 14**) represents data from five exploratory wells with the depth of cross section varying from 156 m bgl to 200 m bgl for 106 km in the NW – SE direction. The thickness of the Aquifer-I is more in the southwestern part and southeastern parts of the section from Khadakmal to Jivhale and from Chapadgaon to Mirgaon. The thickness of Aquifer – II is more in the NW part of the section line from Khadakmal to Jivhale and decreases in the southeastern part of the section near Mirgaon, where discharge/yield of 1.37 lps has been encountered. The massive thicker part in this section indicates the limited thickness of the deeper aquifer.
