Evaluation of Groundwater Quality of Aligarh City, (India): Using Statistical Techniques Approach

Examination of the idea of groundwater of a particular area has a phenomenal importance in both drinking and irrigational purposes. Water which is essential for all the living beings for their existence and metabolism plays a major role in the ecosystem. Unethical human involvement and exploitation of the groundwater resources leads to water quality degradation. Present examination has been directed and administered to analyze the chemistry of groundwater of the Aligarh city. This has been led by collecting the groundwater samples of the study area and subjecting the samples to the entire physicochemical investigation. Groundwater samples were collected from 45 different reviewing stations line missing during the year 2016 for the appraisal of groundwater nature of the study area. High coefficient of variance indicates variability of the physicochemical parameters and groundwater samples concentration. The clear measurable investigation was done close to Pearson correlation. From the connection examination, it is discovered that an incredibly strong relationship exists between electrical conductivity (EC) with hardness (0.82), magnesium (0.82) and sulfate (0.81) then again hardness is likewise showing correlation with calcium (0.86), magnesium (0.95) and sulfate (0.83). lead and cadmium fixation in the water samples was observed to be a part of the most extremely reasonable breaking point suggested by Bureau of Indian Standard (BIS 2012) and demonstrates 100% concentration in groundwater samples of the study area. Concentration of total dissolved solid (TDS), magnesium (Mg), sodium (Na), sulfate (So4), lead (Pb), nickel (Ni), chromium (Cr) and cadmium (Cd) are furthermore found beyond the maximum permissible limit endorsed by Bureau of Indian Standard (BIS 2012). This reveals water quality deterioration in Aligarh city which needs some treatment before consumption and needs to be protected from contamination. It is therefore suggested that a regular monitoring of groundwater is carried out.
