However, the number of most polluted stretches is practically unchanged.<\/p>\n<h5>About the working of CPCB report on water quality<\/h5>\n<p>The CPCB network monitors water quality at 4,484 locations across the country.<\/p>\n<p><strong>Conditions for determining water quality<\/strong>: <strong>a)<\/strong> Biochemical oxygen demand (BOD) exceeding 3 milligrams per litre (mg\/l) is identified as polluted locations, <strong>b) <\/strong>A BOD less than 3 mg\/l means the river stretch is fit for \u201coutdoor bathing,\u201d\u00a0and <strong>c)<\/strong>\u00a0Two or more polluted locations identified on a river in a continuous sequence are considered as a \u201cpolluted river stretch.<\/p>\n<p><strong>Categorisation<\/strong>: There are five priority categories. <strong>1)<\/strong> BOD exceeding 30 mg\/l are considered \u201cPriority 1\u201d (P1), meaning, the most polluted and thus needing the most urgent remediation, and <strong>2)<\/strong> The rest of the categories \u201cPriority 2\u201d (P2) to P5 were defined based on BOD less than 30mg\/l.<\/p>\n<p><strong>Significance<\/strong>: The success of river-cleaning programmes are measured by the number of stretches moving from 1 to 2, 2 to 3 until those in 5 (requiring the least action) to reduce.<\/p>\n<p><strong>Reason for the report<\/strong>: The National Green Tribunal passed orders that the CPCB and the Jal Shakti Ministry monitor river pollution and ensure that it was dealt with. Every State had to ensure that at least one river stretch was \u201crestored\u201d to at least be fit for bathing.<\/p>\n<h5>About the recent CPCB report on water quality<\/h5>\n<p>There is almost no change\/slight change in the P1 and P2 categories of polluted river stretch from 2018 and the present report. This indicates that further stringent actions are required for control of organic pollution from various point sources of pollution including the development of infrastructure and its proper operation for treatment of wastewater before discharge into recipient water bodies,<\/p>\n<p><strong>Performance of states<\/strong>: <strong>Gujarat and Uttar Pradesh<\/strong> had the highest number of \u201cPriority 1\u201d river stretches (6). <strong>Maharashtra<\/strong> had the most polluted river stretches of 55, followed by Madhya Pradesh (19), Bihar (18), and Kerala (18).<\/p>\n<p>The overall decrease in the net number of identified polluted river stretches, which have shown improvement in water quality, \u201ccould be attributed\u201d to the efforts done for infrastructure development for pollution control.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Source: The post is based on the article \u201cCPCB report shows fewer polluted river stretches, but worst ones remain unchanged\u201d published in The Hindu on 26th December 2022.\u00a0 What is the News?
