Two sets of radon detectors are also available in the laboratory.
The laboratory is also equipped with Ion Chromatograph System-5000 of Dionex for analysis of ions, heavy metals, pesticides, carbohydrates etc. This instrument is useful in assessment of water quality and being used for various studies in the division.
Facilities of the laboratory were extended to Regional Centres and other divisions of the Institute for their technical studies. Facilities of the laboratory were also extended to various other departments/agencies like; PRL, Ahmedabad; NGRI, Hyderabad; JNU, New Delhi; NCAOR, Goa, IIT, Roorkee, IIT, Kanpur; IIT, Guwahati; Delhi University, Annamalai University; Central Ground Water Board etc.
During the year 2015-16, more than 8,000 water samples (precipitation, rivers, springs, air moisture and groundwater) were analyzed for δ2H and δ18O. Around 250 water samples were analyzed for environmental tritium and around 1600 water samples were analyzed for water chemistry on Ion Chromatograph.

Snow & Glacier Laboratory and Hydro meteorological Observatory

National Institute of Hydrology has been carrying out hydrological studies since 1999 on Gangotri Glacier, which is one of the biggest glaciers of Himalayas. In the Snow and Glacier laboratory analysis and modelling of Snow and Glacier melt runoff, based on the observations taken at the Gangotri site of the meteorological observatory with AWS established at Gangotri Glacier at an altitude of 3600 m are carried out. A stream flow discharge site is also being maintained at that location. A conceptual model for simulating snow and glacier melt runoff has been developed at the institute and is being applied for snow and glacier modelling at this lab. Since most of these facilities are at harsh location and inaccessible sites the details of studies are exhibated for the visitors. For local common people a weather display unit is installed over the main building. It displays the instantaneous temperature and relative humidity. The weather parameters observed on previous day are also displayed. The control unit and operation facility is being maintained in the laboratory.
