ABSTRACT

 

In this study statistical techniques were applied to groundwater quality data to investigate seasonal variability of groundwater quality parameters in Aligarh city area, India. Groundwater samples were collected from 40 wells and analyzed for 20 water quality parameters in pre and post monsoon seasons during the year 2014. Our finding indicates that concentration of pH, total dissolved solids, Iron, Sulphate, Chloride, Alkalinity, Total hardness, Calcium, Magnesium, Copper, Manganese, Lead, Chromium and Cadmium were found above the standard limits prescribed by BIS. The results revealed that groundwater quality were distinctly different between two seasons. The study also indicates that a moderation in water quality was observed after the monsoon season which can be attributed to a possible dilution due to clear groundwater recharging effect of precipitation by monsoon.
