Bangalore's ground water has high radon content

A survey by Central Ground Water Board (CGWB) has revealed that Bangalore city’s ground water contains high level of radioactive gas radon.

The CGWB, under the Ministry of Water Resources, said all the samples collected from Bangalore city for the survey had high radon content exceeding 11.1 Bacquerel per litre, according to the maximum permissible limit determined by the US Environmental Protection Agency.

The CGWB collected around 80 samples from various parts of southern Karnataka, including 30 samples from Bangalore city, all of which had high presence of radioactive gas radon, said union minister for water Harish Rawat in his written reply to the Rajya Sabha on Thursday.


Thirty-six out of the total 39 samples collected from Tumkur district and one out of seven samples collected from Chamarajnagar district also recorded high radon content.

However, test on borewell water taken from Mysore showed that radon content was within the permissible limit in the district. A carcinogenic substance, traces of radon in high levels could directly cause stomach and lung cancer, according to experts.  The permissible level of radon is 11.83 Bq/litre. Levels of radon in Bangalore’s ground water is estimated between 56 Bq/l and 1000 Bq/l. “Radon contamination, geogenic in nature, above permissible limit is generally present in freshly pumped water”, said the Minister in his reply.

Radon has a life of only 3.8 days, as its concentration changes significantly on abstraction, aeration, storage and boiling.

Hence, groundwater pumped from borewells and stored in overhead tanks is safe for consumption. 

The radon gas escapes into the atmosphere drastically reducing its concentration in water, making it safe for drinking.
 

‘Water crisis will be solved in 24 hrs’

‘Water crisis will be solved in 24 hrs’

Kochi: State Water Resources Minister P.J. Joseph accompanied by additional chief secretary V.J. Kurien on Thursday stepped in, in an effort to put an end to the drinking water woes plaguing the district on account of two pipe bursts in a span of two weeks. The pipe bursts are yet to be plugged.

After holding a two-hour meeting with officials of the Kerala Water Authority and district administration including District Collector P.I. Sheik Pareeth in the presence of MLAs Hibi Eden, Dominic Presentation and Benny Behnan and Kochi Mayor Tony Chammany, the Minister promised that the issue would be resolved in 24 hours.

The pipe bursts at Aroor and Kumbalam toll plaza left areas under Maradu Municipality, Kumbalam, Kumbalanghi and Chellanam without drinking water supply forcing restive people to take their protests to the streets on Thursday. This forced officials and the people’s representatives to call an emergency meeting at the Ernakulam guest house.

The Minister said that stronger DI pipes which can withstand the load of heavy vehicles would be installed on the national highway. “The crack developed at Kumbalam because the old type of pipe could not withstand the weight of heavy vehicles which began passing through the road in recent times. We will replace them,” he said.

He said a KWA team will study Ernakulam’s water woes and submit a report in 10 days and action would be initiated based on that. He said that in areas where old pipes were laid, a parallel network with DI pipes would be laid.

A Rs 900-crore project too is in the pipeline to end the drinking water woes of Ernakulam. The JNNURM drinking water project which would be commissioned in December would be able to solve the issue to a great extent, the Minister added.

Hyderabad to face 100% water tariff hike

Picture for representational purpose only.

Hyderabad: Industries and commercial establishments in and around the city should brace for a steep hike in drinking water tariff as the Hyderabad Water Board has proposed a 100 per cent hike. However, domestic consumers will be spared.

Department officials will make a detailed presentation to Chief Minister Kiran Kumar Reddy regarding the necessity to hike the tariff.

The CM’s approval is mandatory to revise tariffs as he is the chairman of the Water Board. “We are expecting to meet the Chief Minister within a week,” said a senior official.

The Water Board, which hopes to raise Rs 600 crore through the tariff hike, has blamed the electricity tariff hike and FSA charges in power bills for compelling it to propose the tariff hike.

Sources said that the Board’s expenditure has crossed Rs 1,000 crore against its annual income of Rs 750 crore. The establishment charges are all set to go up due to the pay revision. Water tariff had been hiked for consumers of all categories in December 2011.

The Board consumes huge electricity to pump Krishna, Manjira and Singur water to the city and its electricity dues have touched nearly Rs 300 crore.

Highly placed sources told DC that Water Board officials have also proposed an “annual automatic tariff revision” for all category consumers in addition to the main proposal of 100 per cent increase in water tariff for industrial and commercial consumers.

There are 1,500 industrial and water-based industrial connections that together pay nearly Rs 220 crore water bills every year. The Board wants to collect over Rs 440 through the hike.
