Different states of our country facing problem to different extent to use both ground water and surface water to use as a source of drinking water supply. Both ground and surface water can be contaminated by chemical naturally as well as by the human activities. Due to the poor sanitation in the surrounding area of the supply drinking water can also be contaminated by bacteria. In northern India water is being contaminated by the chemicals like nitrate, total dissolved solids (TDS), Fluorides and iron along with infectivity from faecal coliforms. Depending on their concentration it causes a great health impact on users. Excess of iron causes water unsuitable for use in washing, cooking etc. To overcome this quality problem different laboratories are established in different states of our country. At Gram Panchayat level, Self-employed mechanics (SEMs) offers a very exciting service to society by caring out for spot sources inside the GP. SEMs will turn into the foundation of the monitoring and response to bacteriological quality at proletariat. Currently it is suggested that SEMs will take water samples in H2S ampule of different sources for two times in a year and store them under room temperature at block office. Once most of sources are free from bacteriological pollution consistently and for at least a half year, the recurrence of testing might be diminished from month to month to once a quarter and at last to pre and post monsoon at the care of the Executive Engineer. It is typical public norm to have a stock of 15 physico-chemical boundaries of all drinking water sources. In contrast to bacteriological quality, which will in general change after some time and with season, the chemical quality remains more secure, The tends of alteration observed after along gap and sometimes it occurs seasonally. So it is more convenient to test the 15 parameters after a long period of time. The tests are conducted on a regular basis by the different Laboratories of Districts and in the sub-division level: bacteriological analysis two times and chemical analysis to be done once in a year. According to GoI convention, every research center will complete 3000 samples for each year. Research and development is also an additionally significant part of a provincial DWQM framework. It will incorporate appraisal of probable customer agreeable innovations supporting R&D on treatment advancements with potential for huge scope application, wholesome mediation, wellbeing concentrates on impacts of high fluoride and nitrate in drinking water. Presumed research establishments might be designated to attempt R&D plan. Research and development theme work should be with the end goal that it has either suitability for application for a huge scope or helpful in taking enormous strategy decisions.
