The ground water quality of the 14 Metropolitan Cities of Faridabad, Delhi, Jaipur, Bhopal, Indore, Jabalpur, Nagpur, Nasik, Pune, Bangalore, Hyderabad, Vishakhapatnam, Patna and Kochi has been assessed to see the suitability of ground water for domestic and irrigation applications. Twenty five ground water samples were collected each during pre- and post-monsoon seasons in the year 2004 and analysed for various physico-chemical and bacteriological parameters, heavy metals, pesticides and polynuclear aromatic hydrocarbons.

In a study by the Central Pollution Control Board, the Bharalu and Kolong rivers of Assam have featured among 71 most polluted in the country.

The river Bharalu and Kolong are among the 71 most polluted stretch of river in the country, according to a study by the Central Pollution Control Board (CPCB).

No respite for the Capital's residents any time of the day: Pollution Control Board

With nearly all residential societies, malls, offices and homes surviving on generator sets in Gurgaon, serious air pollution is but only inevitable. According to Central Pollution Control Board (CPCB) sources, levels of particulate matter exceed prescribed limits for most of the day several times over in the city. An analysis in December 2005 revealed that against a prescribed limit of 80 micrograms/cubic metre, NO2 averaged 283 micrograms/cubic metre. PM10 was a whopping 721 micrograms/cubic metre against a limit of 100. The levels of CO shot up three times to 6,240 micrograms/cubic metre against the permissible limit of 2,000 in the evenings. The alarm bells started ringing then, and matters have only become worse since. According to CPCB, pollution from generator sets stands second only to vehicular pollution, and in a city like Gurgaon, which is completely generator-dependent, the situation is close to getting out of hand. Gensets emit dangerous gases like CO and NOx which have a terrible impact on health thanks to greater personal exposure levels.

Data generated by CPCB of ambient air quality in various cities and towns of India under National Air Quality Monitoring Programme (NAMP) have been analyzed. A decreasing trends has been obseved in ambient sulphur dioxide levels in many cities like Delhi, Hyderabad, Kanpur, Lucknow, Mumbai etc. This may be due to various interventions like reduction of sulphur in diesel, use of CNG as the vehicular fuel in Delhi and Mumbai etc.

Data shows noise due to traffic during the day is much higher than what is good for general public

Nano could spell further privatisation of transport, more traffic congestion and pollution, and

Around the world as countries are struggling to arrive at an effective regulatory regime to control the discharge of industrial effluents into their ecosystems, Indian economy holds a double edged sword of economic growth and ecosystem collapse. This situation if mishandled can cause irreparable ecological harm in the long term well masked by short term economic prosperity.

the Central Pollution Control Board (cpcb) has recently come up with a draft guideline for the cement sector to reduce fugitive emissions. Fugitive emissions occur primarily due to poor handling
