Combined Geo-Scientist Salary & Job Profile
Last verified 31 Jul 2026
UPSC Combined Geo-Scientist posts carry Pay Level 10 of the 7th CPC Pay Matrix for Group A posts; Pay Level 7 for the Group B Assistant grade posts in the Central Ground Water Board, plus Dearness Allowance, House Rent Allowance and Transport Allowance.
Posts and pay
Geologist, Geophysicist and Chemist (Group A) in the Geological Survey of India under the Ministry of Mines, and Scientist B and Assistant grade posts in the Central Ground Water Board under the Ministry of Jal Shakti.
Allowances
| Component | Detail |
|---|---|
| Dearness Allowance | Revised twice a year as a percentage of basic pay |
| House Rent Allowance | Depends on the class of the posting city (X, Y or Z) |
| Transport Allowance | As per city classification and pay level |
| Other benefits | Official accommodation or lease, medical cover, provident fund, pension under NPS or UPS, and leave travel concession |
Because HRA and Transport Allowance are city-linked, two officers on identical basic pay take home noticeably different amounts — a metro posting pays more in allowances than a district posting, though the district posting usually comes with official accommodation and a vehicle.
Career progression
Promotion follows time scales fixed for the service, moving through Junior Time Scale, Senior Time Scale, Junior Administrative Grade, Selection Grade and above. The pay matrix levels rather than the entry salary are what make these posts competitive over a career.
