GROUND WATER AND ENVIRONMENTAL GEOLOGICAL STUDIES

Ground Water Investigations:
Electromagnetic and deep resistivity survey for assesment of hard rock aquifers in Quetta Valley and surrounding areas.

Impending crisis of evacuating Balochistan's capital was averted through GSP's success in finding large quantities of good quality, ground water in hard rock aquifers in and arround Quetta valley.

Ground water investigations were also caried out in other parts of the country. Despite paucity of operational funds and field worthy vehicles, the GSP is striving hard to come to the expectations of the nation.

Electro-Magnetic and Resistivity Survey for hard Rock Groundwater exploration in the quetta valley and surrounding areas

Integrated geophysical survey comprising of Electro-magnetic profiling and deep electrical resistivity soundings in the Quetta valley and surroundings have been conducted for the assessment of hard rock aquifers specially the Jurrasic-Tertiary limestones.The survey forms a major part of hydrogeological investigations carried out from the pilot to investigation phase of Balochistan Water and Sanitation Authority (B-WASA) programme of Quetta. Water supply and Environmental Improvement Project(QWSEIP).

The project initated in early 2000 and the field work was completed by late 2003. 175 line Kms of reconnaissance EM profiling and more than 300 resistivity probe soundings averaging 100 meters exploration depth has been accomplished .The investigations have indicated the Chiltan limestone as a primary hard rock groundwater resource for the Quetta valley and surroundings. Dungan and Kirthar limestone also have a potential for good yielding aquifers.The tested discharge from the bore holes drilled have quantified more than 20 mgd of hard rock groundwater resource which could be tapped for augmenting the water supply and ameliorating the pressing demand for more water in different sectors.
