GPCB Senior Scientific Assistant Recruitment 2025 — 105 Vacancies via GSSSB | Gujarat Pollution Control Board

GPCB Senior Scientific Assistant Recruitment 2025: Complete Official Guide

The Gujarat Pollution Control Board (GPCB), one of the most important statutory bodies in Gujarat under the Forest and Environment Department, has announced a significant recruitment drive for 105 Senior Scientific Assistant (Class-III) positions. This recruitment is being conducted through the Gujarat Subordinate Service Selection Board (GSSSB) and targets science postgraduate candidates who wish to build a meaningful career in environmental protection, pollution monitoring, and scientific research.

This is a rare opportunity — government science jobs that directly impact environmental policy are limited, making the GPCB SSA recruitment one of the most prestigious in Gujarat’s state government hiring landscape.

About GPCB: Your Future Employer

The Gujarat Pollution Control Board was established under the provisions of the Water (Prevention & Control of Pollution) Act, 1974 and is also entrusted with the implementation of the Air (Prevention & Control of Pollution) Act, 1981 and the Environment Protection Act, 1986 in Gujarat.

Key functions of GPCB:

• Monitoring water quality of rivers, lakes, coastal waters, and groundwater
• Issuing Consent to Establish (CTE) and Consent to Operate (CTO) for industries
• Regulating industrial effluent and air emissions
• Conducting environmental impact inspections and compliance audits
• Managing Hazardous Waste and Biomedical Waste disposal systems
• Running Environmental Monitoring Labs across all major industrial clusters

Gujarat being India’s most industrialized state — home to chemical clusters in Ankleshwar and Vapi, petrochemical hubs in Vadodara and Surat, and the massive Dahej PCPIR (Petroleum, Chemical, and Petrochemicals Investment Region) — GPCB plays an absolutely critical governance and regulatory role.

Working for GPCB means you will be at the intersection of science, law, industry, and public health — a truly dynamic career path.

Job Profile: What does a Senior Scientific Assistant at GPCB do?

Understanding what you will actually do on the job is critical before you apply. Here’s a realistic view of the role:

Day-to-Day Responsibilities

1. Water Quality Monitoring You will collect water samples from rivers, lakes, industrial discharge points, and groundwater bores as part of GPCB’s National Water Quality Monitoring Programme. Samples are sent to GPCB’s accredited environmental laboratories for testing of parameters like BOD, COD, pH, heavy metals, coliform bacteria, dissolved oxygen, and suspended solids.

2. Industry Inspections Senior Scientific Assistants accompany Environmental Engineers on factory inspections. You will check compliance with Consent to Operate (CTO) conditions, take samples from industrial effluent treatment plants (ETPs), inspect chimney emissions, measure ambient air quality, and verify stack emission records.

3. Laboratory Analysis (for lab-based postings) In GPCB’s regional labs, SSAs perform chemical and biological analysis of environmental samples. This involves operating advanced equipment like Atomic Absorption Spectrometers (AAS), Gas Chromatographs (GC), Ion Chromatographs, UV-Vis Spectrophotometers, and TOC Analyzers.

4. Data Recording & Technical Report Preparation All monitoring results must be meticulously recorded in government-prescribed formats. SSAs prepare technical reports that are submitted to higher-level officers and, in some cases, to the National Green Tribunal (NGT) or Ministry of Environment & Forests.

5. Biomedical and Hazardous Waste Oversight Monitoring hospitals, clinics, and chemical factories for compliance with Biomedical Waste Management Rules (2016) and Hazardous and Other Wastes (Management) Rules (2016).

6. Public Grievance Response GPCB receives public complaints about pollution. SSAs are sometimes deputed to investigate these complaints in the field.
