Kolar District, which has a tropical climate all year long, owes its prosperity and growth to the old tanks that once stood there. The most tanks in the State are 2980, which is the total number. Agriculture is the majority of peoples' jobs. Groundwater is the primary source of irrigation in the absence of surface water irrigation systems. The District has the most bore wells in the State-roughly 29936-as well. Only 748 mm of rain falls on average each year in the semi-arid District. Furthermore, the rain is more irregular and groundwater is largely exploited. The annual rainfall was only 521 mm in 2015 compared to 1,195.4 mm in 2005. Farmers began drilling bore wells in the early 2000s because there was no surface water and no effective way to replenish water aquifers. Water quality is crucial at the same time. As a result, a study on total hardness in groundwater samples was conducted. Samples were collected seasonally from fifty different bore wells scattered throughout the five different talukas of Kolar District, and total hardness as well as other parameters of groundwater samples were analyzed. The findings of the analysis revealed that only a small number of the samples had concentration levels that were greater than the acceptable limit and only a small number had concentration levels that were within the acceptable range. Consequently, it is advised that the water be adequately treated before consumption.
