Data Sources and Processing

Abstract

This chapter provides the data from various sources and discusses the processing of data. The major data required for the work are the input–output table of India, the different types of water pollutants generated by the different industries of India, and the abatement cost for various water-polluting industries. The study has used the input–output table of India for the year 2006–2007 recently prepared by the CSO (Input-output transaction table 2006–2007. Central Statistical Organisation, Ministry of Programme and Implementation, Government of India, 2011). The input–output table of 2006–2007 consists of 130*130 sectors. For our study, the table has been aggregated to 38 sectors. From the publications of the Central Pollution Control Board and various other water pollution information sources, ten types of water pollution parameters are identified which are being discharged by the different industries. These are suspended solids (SS), dissolved solids (DS), chloride, sulfide, zinc, phenol oil and grease, biochemical oxygen demand (BOD), chemical oxygen demand (COD), and other pollutants such as nitrogen, chromium, cyanide, alkalinity, etc. A large number of industries do not conduct systematic record of effluent. However, we are able to collect the pollution data for 31 sectors. We have estimated the abatement cost for the treatment of water pollution for each individual sector. Due to the paucity of the cost data, we could collect the data for 16 sectors. The issue with data limitation is also discussed in this chapter.
