In the absence of any stringent norms on water, the existing methodology for Water Quality Management (WQM)is inadequate to identify the various sources of pollution. Integration of data on water quality with data on water supplies, which is very important from the point of view of assessing water availability for meeting various social, economic and environmental objectives, is hardly done. Finally, in the absence of any stringent norms on water quality testing, results can change across agencies depending on sampling procedure, time of testing, and testing instruments and procedure. Thus, water quality testing is tangent to a large group of beneficiaries. That is why development of simple and fast water quality detection kits is essential to test, validate and implement state-of-the-art, innovative, accurate, robust, reliable and cost effective rapid water quality monitoring tools in Indian context.

Some data : In the last two decades, groundwater which is the major source of drinking water in Bihar, has been found to be contaminated with pollutants like Arsenic, Fluoride, Iron and Nitrate, which have resulted in serious concerns about water quality in Bihar and their health impacts. Out of 38 districts, 19 districts are affected with Arsenic, 11 districts are affected with Fluoride, 9 districts are affected with Iron, and 6 with nitrate contents above permissible limits. Recent studies indicate that the intensity and spread of these contaminations in groundwater sources are increasing with increasing dependence on the state’s groundwater reserves. Infrastructural and manpower shortages are preventing successful implementation of the water quality maintenance protocol as envisaged in NRDWQMSP. Also the state and district-level laboratories are facing severe time constraints to meet the growing demand for identification of clean water sources, mainly due to the distances to be covered between the water sample collection points and the laboratories. The first step towards evolving measures to prevent and cure groundwater quality deterioration is generating reliable and accurate information through water quality monitoring (WQM) to understand the actual source/cause, type and level of contamination. However, there are a few observation stations in the country that cover all the essential parameters for water quality and hence the data obtained are not decisive on the water quality status. Secondly, WQM involve expensive and sophisticated equipment that are difficult to operate and maintain and require substantial expertise in collecting, analyzing and managing data. Since water technology is still not advanced in India, the available data is less reliable. The existing methodology for WQM is inadequate to identify the various sources of pollution. Integration of data on water quality with data on water supplies, which is very important from the point of view of assessing water availability for meeting various social, economic and environmental objectives, is hardly done.
