Impact Assessment of water quality for ground water parameters on kalingarayan canal, Erode District, Tamil Nadu

In this study, Kalingarayan canal is selected for the analysis of pollution level, i.e., the analysis to which certainty the canal is subjected to pollution. The Kalingarayan canal is crossing the major textile units. The streams carrying the untreated or semi-treated industrial effluents are mixed into the canal. In order to understand the pollution status of the canal, nine ground water samples along the canal namely Panjalingapuram towards north direction, Kolathupalayam I towards south direction, Kolathupalayam II towards north direction, Unjalur I towards north-east direction, UnjalurII (hospital) towards north-east direction, Perumparai towards north-east direction, Vadakupudupalayam I towards north direction, Vadakupudupalayam II towards north direction and Sallikadu towards north direction (GW1-GW9) were collected from the downstream side of the canal during the period 2014 – 2016. From the study, it can be concluded that the quality of water was considered to be bad at sampling stations Kolathupalayam (GW3) and Perumparai (GW6) and there were no significant changes in the characteristics of groundwater during flow and non-flow period. It can also be seen that the water is highly polluted with nitrate, calcium and magnesium, cannot be used for any kind of industrial processes and human consumption without proper treatment.
