Water quality assessment of denkada anicut, vizianagaram district, India

Seasonal variation in the physico chemical parameters, water quality assessment using WQI method, irrigation water quality assessment and heavy metal analysis was reported in the present paper by the authors. The work is carried out for the water samples collected from Denkada anicut of Vizianagaram district of Andhra Pradesh, India. The samples were collected and analyzed for eleven different seasons such as August 2010, December 2010, April 2011, August 2011, December 2011, April 2012, August 2012, December 2012, April 2013, August 2013 and December 2013. All the physico- chemical parameters analyzed were compared with IS: 10500 standards and found to be well within the values prescribed. It was found that the quality of the water samples was rated as excellent with respect to the water quality index (WQI) calculations. The parameters such as SAR, RSC, %Na and Mg hazard were also found to well within the prescribed standard values. Inferring that the water is suitable and rated as Good for irrigation and agricultural purpose. From the ICP analysis report it was found that except Si all other metals analyzed were below detection limits.
