THE RESULTS

Based on the interpretation of resistivity soundings i.e. VES No-1 located at (29.83835,

71.92935) and VES No-2 located at (29.83519, 71.92393), following results have been

deduced;

Depth to water table varies from 14 - 16 meter in the area.

Subsurface lithology is dominantly fine to course Sand with inter-bedding of clay of

variable thickness.

The area has been distributed into three major resistivity zones, described below;

ZONE ABOVE WATER TABLE

This zone extends up to15 meter depth in the area. The resistivity values in this

zone are haphazard depending upon many natural and cultural factors like surface

materials, their compactness and moisture contents etc.

HIGH RESISTIVITY ZONE

Interpreted resistivity values ≥50 Ohm-m constitute this zone. The interpreted

lithology for this zone is mainly composed of medium to coarse Sand.

This zone containing fresh groundwater quality has been interpreted on both VES

points and is generally 25-35 meter thick at the observed locations. Estimated

Electrical Conductivity (EC) of the fresh water in this zone is 675 - 1200 µs/cm and

mineral content i.e. total dissolved solids (TDS) are 450 - 800 ppm.

LOW RESISTIVITY ZONE

Interpreted resistivity values ≈ 10-25 Ohm-m falls in low resistivity zone. Interpreted

lithology for this zone is predominantly fine to medium grained Sand with clay layers

of variable thickness.

This zone is interpreted to be having brackish / moderately saline groundwater

quality. Estimated Electrical Conductivity (EC) of the groundwater in this zone is

≥ 2400 µs/cm and mineral content i.e. total dissolved solids (TDS) are ≥ 1200 ppm.

RECOMMENDATIONS

Based on the results of ERS surveys conducted in the area three hydrogeological

zones have been identified. Following parameters are recommended for safe

installation of tubewell in the area.

High Resistivity Hydrogeological Zone is favorable for drawing fresh water from

water table to 40 meter depth at VES-1and up to 40 meter depth at VES-2.

Geophysical logging, comprising SN, LN, SP, SPR and Natural Gamma will be

mandatory in the open hole for safe design and accurate placement of screen/filter.

THE RESULTS

Based on the interpretation of resistivity soundings i.e. VES No-1 located at (29.52236,

71.53577) and VES No-2 located at (29.52655, 71.53564), following results have been

deduced;

Depth to water table varies from 16 - 21 meter in the area.

Subsurface lithology is dominantly fine to course Sand with inter-bedding of Clay of

variable thickness.

The area has been distributed into three major resistivity zones, described below;

ZONE ABOVE WATER TABLE

This zone extends from 16 to 21 meter depth in the area. The resistivity values in

this zone are haphazard depending upon many natural and cultural factors like

surface materials, their compactness and moisture contents etc.

HIGH RESISTIVITY ZONE

Interpreted resistivity values ≥50 Ohm-m constitute this zone. The interpreted

lithology for this zone is mainly composed of medium to coarse Sand.

This zone containing fresh groundwater quality has been interpreted on both VES

points and is extends up to 80 meter depth in the area. Estimated Electrical

Conductivity (EC) of the fresh water in this zone is 675 - 1200 µs/cm and mineral

content i.e. total dissolved solids (TDS) are 450 - 800 ppm.

LOW RESISTIVITY ZONE

Interpreted resistivity values ≈ 10-25 Ohm-m falls in low resistivity zone. Interpreted

lithology for this zone is predominantly fine to medium grained Sand with clay layers

of variable thickness.

This zone is interpreted to be having brackish / moderately saline groundwater

quality. Estimated Electrical Conductivity (EC) of the groundwater in this zone is

≥ 2400 µs/cm and mineral content i.e. total dissolved solids (TDS) are ≥ 1200 ppm.

RECOMMENDATIONS

Based on the results of ERS surveys conducted in the area three hydrogeological

zones have been identified. Following parameters are recommended for safe

installation of tubewell in the area.

High Resistivity Hydrogeological Zone is favorable for drawing fresh water from

water table to 85 meter depth at VES-1and up to 70 meter depth at VES-2.

Geophysical logging, comprising SN, LN, SP, SPR and Natural Gamma will be

mandatory in the open hole for safe design and accurate placement of screen/filter.
