Groundwater is water that exists under the Earth's surface and fills all or part of the void spaces in soils and geologic strata. Subsurface water is another name for it. Precipitation provides the majority of ground water. Precipitation seeps into the soil zone beneath the ground surface. In both urban and rural locations, ground water is an important supply of drinking water. For more than half of the country's population, ground water is the only supply of drinking water, and for many rural towns and several large cities, it is the only source of drinking water. Ground water has been an important source of water for many countries' household, industrial, and irrigation sectors in recent years. Because of the greater interaction of groundwater with diverse elements in geologic strata, it contains higher quantities of dissolved components than surface water. The quality of groundwater is determined by a variety of hydrological, physical, chemical, and biological elements. The study area's mining growth necessitates the prudent use of natural resources within the boundaries of acceptable assimilative capacity. As a result, in the region, water quality and management measures have become increasingly crucial. pH, EC, TDS, Total Hardness, Chloride, total alkalinity, Iron, Fluoride, Sulphate, Calcium, Sodium, Magnesium, and Potassium are among the physico-chemical parameters that will be evaluated in this study. The investigation will also determine whether ground water is suitable for drinking and irrigation in the Tummalapalle area. Bore wells in and around Tummalapalli village, Vemula mandal, YSR district, Andhra Pradesh, yielded a total of 12 samples. The data clearly reveal that some quantities in each of the 12 samples fall within the WHO permitted limits. The remaining metrics, such as EC, total alkalinity, total hardness, magnesium, and sodium, exceed the WHO acceptable limit.
