HYDROCHEMICAL STUDIES

CENTRAL CHEMICAL LABORATORY, NORTHERN REGION, LUCKNOW

         The Central Ground Water Board, being an apex body of Govt. of India has the responsibility of investigating quality and quality of ground water and management, exploration of ground water resources. These activities are in support of the overall mission of Central Ground Water Board. The results of these investigations are used not only to document water quality and quantity but also to predict changes that may occur because of environmental disturbances, either natural or anthropogenic. These information allow the Central Ground Water Board to develop, maintain and manage water resources more effectively and efficiently. At present entire country is covered by eighteen Regional Offices supported by 27 divisional offices and District unit offices. The Uttar Pradesh and Uttaranchal states are covered by Northern Region with its Head office at Lucknow for quality study the Northern Region has well established and well equipped Chemical laboratory with a team of well experienced expert chemists. It is the largest chemical laboratory of the department and had been declared as Central Chemical Laboratory. It has got facilities to measure major and minor dissolved inorganic constituents, Heavy & Toxic elements, organic pollutants. The major equipments are conductivity Meter, pH meter , UV-VS Spectrometer, Flame Photometer, Nephelometer, select ion meter, micro balances, Atomic Absorption Spectrophotometer, Gas Chromatographs, Vadose Zone Sampler etc.

      A few year back, the Northern Region Chemical Laboratory received Atomic Absorption Spectrophotometer, Select Ion Meter, Gas chromatograph from Japan under JIC A Oil.

             The Atomic Absorption Spectrophotometer (SHIMADZU AA-670IA) is equipped with Graphite Furnace, HVG and MVU, auto sampler attachments. On which 23 elements (Cr,Co,Cd, Mn,Fe,Sr, Ph, Zn, As, Hg, Se, Al, Sb, Sn, Br, Ba, Ca, Cu, Li, Mg, Mo, Ni, Ag) can be measured. There are two Gas chromatographs with auto sampler and Cr-7A attachments and are provided with ECD, FPD,FTD and FID detection and thus all organic pollutants ( Pesticides) can be analysed.

              In routine 2500 -3000 samples are analysed in the chemical laboratory for Basic parameter, Heavy/ Toxic elements.

              Special studies carried out by Northern Region-

1.Pollution of ground water due to Heavy metals in parts of Uttar Pradesh

2.Chromium pollution in Kanpur Metropolitan

3.Ammonia pollution in Panki Industrial area, Kanpur

4.Occurrence of ammonia in deep aquifer in Meerut

5.Occurrence of arsenic in phreatic aquifer in Uttar Pradesh

            In the coming year the Northern Region chemical laboratory is taking up pesticides studies in drinking water in selected areas.
