Vulnerability to groundwater pollution from Senegal basin was studied by two different but complementary methods: the DRASTIC method (which evaluates the intrinsic vulnerability) and the fuzzy method (which assesses the specific vulnerability taking into account continuity of the parameters). The validation of this application has been tested by comparing the membership in groundwater and distribution of different classes of vulnerabilities established as well as the nitrate distribution in the study area.

The disposal of bottom ash in the thermal power plant is a challenging task. The objective of the present study was to investigate the leaching characteristics of the bottom ash disposed in ash pond of thermal power plants. The studies were conducted with bottom ashes from ash disposal system. A series of leaching test have been performed with different liquid to solid ratio (L/S). The (L/S) varies from 20:1 to 60:1. It is observed that the elements of Mn, Mg, Cr, Zn, Ni, and Cu are most abundant elements while Pb, Mo, Fe and Co are the least abundant elements.

The textile industry’sexcessive water use and contribution to ever-worsening environmental degradation in countries of production, particularly the so-called global South, is increasingly putting it under public scrutiny. However, this sector of the economy also provides important income opportunities to skilled and unskilled labor alike, not least women, and brings much-wanted economic growth. India was the third largest exporter of textiles in 2015and the sector generates direct employment to more than 45 million people, making it the second largest after agriculture.
