Relation between water availability and human population of an area, by taking water pollution into account

Abstract

The population of a human settlement in an area depends on the water availability and water pollution of that area. The paper aims to explain the relationship among them with a new law and give a mathematical formula for calculating the relation. The range of physico-chemical parameters of the water bodies are temperature (14.8 °C-17 °C), pH (6.05-7.4), alkalinity (115.5 mg/L-122.5 mg/L), total hardness (40 mg/L-167 mg/L), chloride (23.5 mg/L-118 mg/L), DO (4.6 mg/L-17.2 mg/L), TDS (49 mg/L-580 mg/L). The study revealed that parameters of water samples from uninhabited areas were within the permissible limit given by BIS (2012) and WHO (2017). But the pH, DO and TDS values of the water samples from inhabited areas were not within the permissible limit.
