Introduction

Central Ground Water Board, North Central Chhattisgarh Region, Raipur carries out analysis of ground water samples regulary for the purpose of monitoring water quality variations in the state. Besides background monitoring, which involves chemical analysis of water samples collected from National Hydrograph Network Stations (377 Nos), water samples from exploratory wells and other special study areas are also analysed.

The lab uses both titrimetric as well as instrumental methods for analysing water samples. The lab has been recently upgraded to 'Level II +' under World Bank aided Hydrology Project.

Equipment

The equipment used in the lab are given below:

Major Equipment
1	Gas Chromatograph	Determination of Organic compounds such as pesticides in water samples
2	Electrode Selective ion meter	Determination of fluoride concentration in water
3	UV-VIS Spectrophotometer	Major ions such as NO₃, PO₄,SiO₂ etc.
4	Flame Photometer	Determination of Alkali metals such as Na and K
5	Turbidity Meter	Determination of Sulphater (SO₄^2-)
6	Conductivity Meter	Determination of Electrical Conductivity of water
7	pH Meter	Determination of pH of water
