Statistical method (Paired t-test) of application to evaluate seasonal variation in concentration of pH in selected groundwater samples of Kolar District, Karnataka, India

Abstract

Water is one of the most unusual natural compounds found on earth, and it is also one of the most important components of life. Presently many current environmental issues (Greenhouse effect, global warming, climate change, acid rain and ozone layer depletion), natural process, variation in geology and anthropocentric activities impose and induces groundwater quality deterioration. The present study is undertaken to analyze, assess and compare the different physico–chemical and biological parameters, mainly more emphasis (concentrated) on pH concentration in groundwater of Kolar District for the period of two years. Range of pH varies from organism to organism. The pH optimum for many bacteria ranges from 3-8, for yeast 3-6, for molds 3-7, for plants 5-6, for animals 5-6 and for human being 6.5-7.5. With regard to statistical analyses (paired t-test and Independent t- test) the pH concentration values were greater than the significance level, hence there was no significant difference in concentration of pH compared to two different seasons of the year 2014 and 2015.
