In 1983, the Indian\ndrinking water standard was published by the Bureau of Indian Standards\n(Drinking Water Specification). The standard has been subject to few revisions\nsince then, with the most recent in 2012.<\/p>\n\n\n\n<p>The 2012 revision was made to improve the standards and align\nthem with international drinking water specifications. Revisions also\nconsidered the most recent information on the nature and concentration of\ncontaminants.<\/p>\n\n\n\n<p>To ensure quality water and protect against pathogens, routine\ntesting, and analysis of drinking waters supplied by Jal Boards or other water\nsupply agencies. The water quality and frequency determine it. Water must be\ntested for impurities and changes in taste or colour. While it is necessary to\ntake safeguards to control contamination of drinking water,&nbsp;<\/p>\n\n\n\n<p>testing must also be undertaken for chlorine-resistant parasites\nthat can get into water like cryptosporidium species and giardia.<\/p>\n\n\n\n<p>In an ideal situation, all samples of water taken from the water\ndistribution system, including consumers&#8217; premises, should be free from\ncoliform and other biological organisms, and bacteriological quality must be as\nper BIS standards. The biological examination is also useful when determining\nthe cause of unpleasant tastes or odors in water. To be safe for drinking,\ncooking, and food processing, water must not contain microscopic organisms like\nalgae, flagellates, and flagellates.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Revised_Specification-_BIS_Standards_for_Drinking_Water\"><\/span>Revised Specification- BIS Standards\nfor Drinking Water<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>BIS standards 2012 has revised the specifications to include\nvirological requirements. BIS has made one of its most significant changes,\nadding virological requirements to the 2012 revised standards. MS2 Phage is an\nindicator of viral contamination in drinking waters. To make water safe for\nconsumption, MS2 Phage must be absent from 1 liter of water. This standard\nclearly states that samples from distribution systems, including those taken\nfrom consumer premises, must be free of viruses.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Nature_and_Significance_of_BIS_Standards_for_Drinking_water\"><\/span><strong>Nature and Significance of BIS Standards for Drinking water<\/strong><strong><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Following is the nature &amp; significance of <strong>BIS Standards for Drinking Water<\/strong><sup><a href=\"https:\/\/en.wikipedia.org\/wiki\/Water_quality#:~:text=Water%20quality%20refers%20to%20the,the%20water%2C%20can%20be%20assessed.&quot;\" class=\"text-primary\"><strong>[1]<\/strong><\/a><\/sup><strong>:<\/strong><\/p>\n\n\n\n<p><strong>Voluntary in Nature:&nbsp;<\/strong>BIS quality standards are not mandatory for civic agencies\nengaged in supplying drinking water to houses across the country.<\/p>\n\n\n\n<p><strong>Significance:<\/strong>&nbsp;Under\nJal Jeevan Mission, as per existing guidelines, IS 10500:2012 is to be adopted\nto ensure a safe drinking water supply.<\/p>\n\n\n\n<p>States\/ UTs have been advised to test drinking water sources\nonce a year for chemical and physical parameters and twice a year for\nbacteriological parameters.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"BIS_Standards_for_drinking_water_quality_%E2%80%93\"><\/span><strong>BIS Standards for drinking water quality &#8211;<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The Central Ground Water Board states that BIS (IS_10500,\nrevised module IS 10500-2012) contains Uniform Drinking Water Quality Monitoring\nProtocol specifications.
