Sanganer has developed as major hub of textile dyeing and  printing. Besides it is also famous for hand made paper. But this is causing havoc to the environment and almost none of the industry has mandatory wastewater purification plants which can be built and insatlled very cheap compared to losses to the environment. Profesor K.P. Sharma of our Department of Botany , University of Rajasthan has developed such a treatment plant but of no avail.  

Textile wastewater is a major source of pollutants. Textile industries consume large amount of water and chemicals for wet processing of textiles. After processing, these industries discharge generally untreated effluents into the Amanishah Nalla or adjoining drains from where they finally reach the Amanishah Nalla. During the course of movement of the effluents, there is considerable amount of infilteration and percolation of the toxic chemicals into the soils thus polluting soil, underground water, pools and vegetation. The chemical reagents used are very diverse in chemical composition, ranging from inorganic compounds to polymers and organic products (Banat et al., 1996). Ingeneral, textile effluents are mostly discharged into the environment after minimal pretreatment with a high amount of pollutants (Oxspring et al., 1993). It is typically grey or coloured, alkaline and high in temperature, BOD₅ (700to 2,000 milligrams per liter (mg/L)) (Park and Shore, 1984) and chemical oxygen demand (COD) (approximately 2 to 5 times the biochemical oxygen demand (BOD) level), solids, oil and possibly toxic organics, including phenols (from dyeing and finishing) and halogenated organics (from processes such as bleaching)(Table 1.2). Dye wastewaters are frequently highly colored and may containheavy metals such as Cu, Cr, Cd, Co, Hg, Ni, Mg, Fe and Mn (Wagner, 1993). Woolprocessing may release bacteria and other pathogens. Pesticides are sometimesused for the preservation of natural fibers and these are transferred towastewaters during washing and scouring operations. Pesticides are also usedfor moth proofing, brominated flame retardants for synthetic fabrics, andisocyanates for lamination.

The toxic effluents from dyeing and printingunits are scattered all over the Sanganer and have polluted soil, water andvegetation (Fig. 1.4 - 1.17). Industrial effluents containing dyes, aniline,caustic soda, acids, bleaching powder, metal ions etc. are discharged into Amanishah Nalla which flows through Sanganer. Water from the nalla is used byfarmers to irrigate their fields. Vegetables grown in these fields are sent tothe market in the urban centre for consumption which cause many disorders and diseases. Workers engagaed in this type of industry also suffer from various health hazards like eczema, contact dermatitis, asthma etc.
