Environmental Data Statistics : CPCB manages environmental data statistic in which air quality data and water quality data comes through. In the case of air quality data, it measures the level of SO 2, NO 2, RSPM and SPM. [27] [28] CPCB measure and maintains water quality data as well. Quality level of river and ponds are the major fields which ...
Delhi Pollution Control Committee was established in 1991 by central government and works with Central Pollution Control Board and National Green Tribunal to control the pollution in the capital. [6] The Committee was established to tackle environmental degradation and pollution in Delhi by monitoring and regulating air and water pollution ...
The Central Pollution Control Board (CPCB) reported that as of 2016, there were 746 industries directly depositing wastewater into the Ganga, which is the largest river in India.

The responsible body for this is the Central Pollution Control Board. [citation needed] Environmental Impact Assessment (EIA) studies need a significant amount of primary and secondary environmental data. Primary data are those collected in the field to define the status of the environment (like air quality data, water quality data etc.).
In general, water quality has improved nationwide since 1972, but not all pollution has been eliminated. Between 1972 and 2001 there was a 12 percent increase in the number of waterways that are safe for fishing.

Between 2009 and 2011, the highest number of lung cancer cases in India were reported from Kolkata, Delhi and Mumbai.
WQT programs can be used to preserve good water quality in unimpaired waters by counterbalancing new or increased pollutant discharges. In impaired waters, a WQT program can be used to improve water quality by reducing pollutant discharges in order to meet a specified water quality standard or total maximum daily load (TMDL). [44]
