ASSESING CONTAMINANT MIGRATION IN GROUNDWATER NEAR MUSI RIVER, TELANGANA STATE, INDIABLESSY GANDURI, UDAYALAXMI G., VIDYASAGARACHARY D. AND RAMADASS GAbstract The indiscriminate disposal of urban and industrial waste water in to open nalas (drains) or water bodies is a common practice in agglomerated metropolis leads to negative impact on the plant, animal and human life and also agrarian produce. Ground water samples collected from the Hyderabad urban periphery (Firzadiguda) downstream area of river Musi to a 60km (Valigonda) long stretch to ascertain the BOD and COD concentrations from pre- and post monsoon seasons (Calender year). There is no notable and or considerable differences in their elevated concentrations from both the seasons (Pre- and Post monsoon). The chemical oxygen demand (COD) concentrations is more than the biochemical oxygen demand (BOD) and both of the them are above their permissible limits for potable, agriculture and other activities. The high BOD indicates the presence of large number of micro organisms which shows the height of pollution. The BOD/ COD ratio is more than 0.5 in the water sample and act as a indicator for high contamination. |
