Analytical laboratory is functioning in the Department since 1992. The activities of the laboratory includes:  

1.         Ambient air quality and Stack monitoring in industries.

2.         Monitoring of industrial effluent.

3.         Noise monitoring

4.         Surface and ground water quality monitoring

5.         Monitoring on festival occasion such as Deepavali, Bhogi and Vinayagar Chathurthi (Ganesh festival) 

 

 The performance of the Laboratory in the Analytical Quality Control exercise was highly appreciated by the Central Pollution Control Board, GOI, New Delhi.  Based on the analytical performance of the Staff during 1992-1995.  Department’s Laboratory has been certified as one of the Tenth best performing laboratory out of 70 Laboratories in our Country.  

Laboratory staff have participated in Analytical Quality Control Exercise (Air Samples) conducted by CPCB and GTZ at New Delhi in All India basis during 5th  –14th , March 2001 at CPCB, New Delhi and stood at third best performing  laboratory at national level.
