Why in the news?<\/h2>\n<\/div>\n<\/div>\n<\/div>\n

Recently, Bhabha Atomic Research Centre (BARC) study concluded that uranium concentrations up to 60 \u00b5g\/l in drinking water are safe, suggesting that the new stricter standard of 30 \u00b5g\/l may be counterproductive.<\/p>\n

BARC Study Findings:<\/h2>\n

1. The Atomic Energy Regulatory Board (AERB) in India previously set the acceptable level of uranium concentration in drinking water at 60 \u00b5g\/l.<\/p>\n

2. In 2021, the Bureau of Indian Standards (BIS) revised the limit to 30 \u00b5g\/l, aligning with World Health Organization (WHO) recommendations.<\/p>\n

3. A study by Bhabha Atomic Research Centre (BARC) scientists concludes that uranium concentrations up to 60 \u00b5g\/l in drinking water are safe, questioning the necessity of the new BIS standard.<\/p>\n

4. The study argues that the more stringent BIS standard of 30 \u00b5g\/l could lead to unnecessary purification costs without significant health benefits.<\/p>\n

5.\u00a0 Citing WHO studies, the BARC researchers state that small concentrations of uranium in drinking water pose no significant health risks, including cancer.<\/p>\n

6.\u00a0 National standards for uranium in drinking water vary globally, with limits in Finland and Slovakia set at 100 \u00b5g\/l and 350 \u00b5g\/l respectively, and South Africa at 70 \u00b5g\/l. Countries like Canada and Australia have lower limits of 20 \u00b5g\/l and 15 \u00b5g\/l, respectively.<\/p>\n

BIS and Health Impact Studies<\/h2>\n

1.\u00a0 The BARC scientists highlight that BIS did not conduct health impact studies before implementing the 30 \u00b5g\/l limit, unlike other agencies such as the US Environmental Protection Agency (EPA), which performed a cost-benefit analysis.<\/p>\n

2. The EPA set the drinking water limit for uranium at 30 \u00b5g\/l after determining that there is no significant difference in health effects between 20 \u00b5g\/l, 30 \u00b5g\/l, and 80 \u00b5g\/l.<\/p>\n

Recommendations and National Considerations<\/h2>\n

1. The BARC study emphasizes the need for country-specific standards considering local geological, socio-economic conditions, and population dynamics.<\/p>\n

2. The researchers suggest that, in the absence of clear evidence of health risks at small concentrations, India should consider retaining the AERB limit of 60 \u00b5g\/l.<\/p>\n

3. The government has stated that uranium in drinking water is naturally occurring and not a result of mining activities.<\/p>\n

Mapping Uranium Concentration<\/h2>\n

1. A comprehensive exercise by BARC researchers in collaboration with over 50 institutions across India showed that:<\/p>\n

i) 94% of 55,554 samples had uranium concentrations below the BIS standard of 30 \u00b5g\/l.<\/p>\n

ii) 98% of samples were below the AERB standard of 60 \u00b5g\/l.<\/p>\n
