Effects of Untreated Textile Effluents on Groundwater near Kodda Gazipur Industrial Area in Bangladesh

Abstract

As a part of rapid expansion in the economy our RMG and textile industries are increasing at a high rate, but due to lacks in our environmental law and regulation, proper disposal of wastewater still remains questionable. Many factories still didn't implement ETPs many factories occupied ETPs but the use of it on regular basis is still dubious. So, it's pretty much hard to guess our groundwater is still safe from contamination. We select two zones one is effected zone and another was non-effected zone and compare their salt concentration and TDS level where the salt concentration is our decision parameter. As most of the textile dyes have a proportional relationship with the Salt level. We selected Kodda Gazipur is our effected zone. We do two-step analysis to make our research done first we do a GIS analysis to illustrate the spatial variation of TDS and Salt concentration for both affected and non-effected zones. Then we do statistical analysis to find out our hypothesis is statistically significant or not. As a result, we found a surprising outcome t(11) = 2.171, p = .053 which means the relationship between textile effluents and groundwater are statistically insignificant.
