Numerous sorts of water contaminants, including pesticides, heavy metals, detergents, household wastes, and fertilisers, were produced as urbanisation and industrialisation advanced. The many sources dispersed these contaminants across the ecosystem.The physicochemical properties of water samples from a few ponds in and around Patna, Bihar, are examined in this study report.pH, electrical conductivity, calcium, phosphorus, total hardness, alkalinity, chloride, dissolved oxygen, temperature, free carbon dioxide, nitrate, and chloride were among the variables examined.The water parameters employed in the current experiment were obviously beyond the surface water contamination threshold, rendering them unusable for a number of applications. A modest attempt has been undertaken in this inquiry to determine how much the water quality has changed in relation to WHO water quality guidelines (WHO).
